Our Corporate History

We were incorporated on May 31, 1994 in the State of Florida as Information Systems Associates, Inc. (the “Company”, “we”, “us”, “our”). Initially, our business operations consisted of consulting services for asset management of large corporate data centers and development and licensing of Information Technology (IT) asset management software. On April 1, 2015, we completed a reverse triangular merger, pursuant to an Agreement and Plan of Merger (the “Merger Agreement”) among Duos Technologies, Inc., a Florida corporation (“DTI”), the Company, and Duos Acquisition Corporation, a Florida corporation and wholly owned subsidiary of the Company (“Merger Sub”). Under the terms of the Merger Agreement, the Merger Sub merged with and into DTI, whereby DTI remained as the surviving corporation and a wholly-owned subsidiary of the Company (the “Merger”). On the same date, TrueVue 360, Inc., a Delaware corporation, became a wholly owned subsidiary of the Company. In connection with the Merger, on July 10, 2015, the Company effected a name change to Duos Technologies Group, Inc.

Overview

The Company, through its wholly owned subsidiary DTI, focuses on the design, development and turnkey delivery of proprietary “intelligent technologies” that enable our customers to derive measurable increases in return on investment for their business. Our technologies integrate with our customer’s existing business process and create actionable information to streamline mission critical operations. Our target market is the largest transportation, industrial and retail corporations representing over $100 billion in total available market. Our technologies have been verified by multiple government and private organizations including Johns Hopkins University Applied Physics Laboratory (JHU/APL), the Department of Homeland Security (DHS) and the Transportation Technology Center, Inc., a wholly owned subsidiary of the Association of American Railroads, and a transportation research and testing organization (TTCI). The Company has worked with these organizations over the past several years where we have supplied funded prototypes of our technologies to verify technology and operating parameters.

The Company provides a broad range of sophisticated intelligent technology solutions with an emphasis on security, inspection and operations for critical infrastructure within a variety of industries including transportation, retail, law enforcement, oil, gas and utilities sectors. In January 2019, the Company launched a dedicated Artificial Intelligence program truevue360™ through its subsidiary, TrueVue360, Inc., (“TrueVue360”) with the objective of focusing the Company’s advanced intelligent technologies in the areas of Artificial Intelligent, Deep Machine Learning and Advance Algorithms to further support our business growth.  Consequently, our business operations are now in three business units: intelligent technologies, AI/machine learning platforms and IT asset management.

Our proprietary applications include but are not limited to:

Intelligent Rail Inspection Portal (rip™)

§

A suite of sub-systems for the automated inspection of freight or transit railcars while in motion. The objective is to automatically detect anomalies such as open or missing hatches, open cargo doors, illegal riders hiding in cargo wells, and an expanding number of mechanical defects, all while the train is traveling through various strategic areas (i.e. border crossings or inspection areas). The anomalies are detected through a combination of visual inspections, utilizing the Company’s proprietary remote user interface which displays ultra-high definition images of a 360-degree view of each rail car, and by a growing number of the Company’s proprietary artificial intelligence (AI) based algorithms. The inspection portal is typically installed between two rail yards and the inspection takes place while the trains are at speed of up to 70 MPH.  A higher speed version is available but not deployed yet as the current market does not yet require the higher speed version. Detections are reported to the respective rail yards well ahead of the train arrival at the yard.

Vehicle Undercarriage Examiner (vue™)

§

A system that inspects the undercarriage of railcars (both freight and transit rail) traveling at speeds of up to 140 miles per hour. The original maximum speed of 70MPH has been superseded by further development work which was completed recently. The addition of algorithms for an increasing number of automated detection of anomalies is a continuing development, which once completed and successfully tested, may have a significant impact on our revenues. The next version upgrade is scheduled to be completed by the end of the second quarter of 2019.

Thermal Undercarriage Examiner

§

Under a development award from the TTCI (the technology evaluation arm of the American Association of Railroads (“AAR”)), the Company developed and deployed a prototype thermal undercarriage examiner during the latter part of 2018.  The system uses high-speed thermal imaging technology to inspect the thermal signature of undercarriage components, with the focus on locomotives. Thermal monitoring of component heat signatures while underway will provide indications of the overall operating health of the locomotive that are not possible to observe during static inspections. Initial system performance has been very encouraging, and the Company received several orders from various class-1 rail operators who will be evaluating the system on revenue tracks. The t-vue design is undergoing further design refinements and sensitivity adjustments and is expected to be deployed commercially by the end of the second quarter of 2019. This system is considered a breakthrough in detection technologies as it is capable of detecting anomalies of trains at speed which were not detectable with currently available technologies.

Multi-Layered Enterprise Command and Control Interface (centraco®)

§

Aggregator and central point for information consolidation, systems management and communications of our proprietary systems and third-party applications.

Tunnel and Bridge Security

§

A suite of intelligent technologies-based homeland security applications for the security of critical tunnels and bridges.

Virtual Security Shield

§

A suite of intelligent technologies-based homeland security applications for the security of critical areas and buffer zones. This application includes intrusion detection zone, Radio Frequency Identification (RFID) tracking and discriminating “Friend or Foe” modules (Friend or Foe refers to a Radio Frequency - based tagging system that validates individuals authorized to be in a specific area).

Facility Safety and Security

§

A suite of intelligent technologies-based homeland security applications for the “hardening” or safety and resilience of facilities against natural or man originated threats for the protection of critical facilities (energy, water, chemical facilities). The Company and most of its staff are CFATS (Chemical Facility Anti-Terrorism Standards) certified.

2

Remote Bridge Operation

§

Proprietary system for remote control of draw bridges.

Pantograph Inspection System

§

A system designed to inspect pantographs (structure connecting transit locomotives to high voltage power lines) for the detection of excessive depletion of carbon liners, which may cause power line ruptures.  The Company is in the process of upgrading these technologies to add 3-D capabilities and artificial intelligence-based automated detection capabilities.

Neural Network Modeling for detection algorithms

§

A neural network is a powerful computational data model, able to capture and represent complex input/output relationships. The neural network includes the development of an artificial system that could perform “intelligent” tasks like those performed by the human brain, including the acquisition of knowledge through deep learning, which is stored within inter-neuron connection strengths known as synaptic weights.

Automated Logistics Information Systems (alis®)

§

We have completed the development and commercially deployed a proprietary intelligent system to automate security gate operations at nine (9) distribution centers owned and operated by a national retail chain.  Leveraging our proprietary multi-layered Enterprise Command and Control Interface technology (centraco®), the automation of gatehouse operations provides significant improvements to efficiency of distribution center traffic flow, resulting in significant ROI to the customer.  The Company initiated marketing this new technology to enterprise-level owners of distribution centers throughout the United States and beyond.

Transit Rail Platform Analytics

§

We have completed our pilot (proof of concept) of our Platform Analytics tunnel and track intrusion technology concept deployed for the New York City Transit Authority (“NYCT”).  The technology is designed to automatically detect objects fouling tracks adjacent to transit passenger platforms and to alert incoming rail traffic to that effect. Field installation of the prototype has been completed and field testing employing our AI application has been conducted since mid-4^th quarter. The NYCT technology team is expected to complete comparative testing during the 2019 fiscal year.

Several new programs, technologies and initiatives are currently under development by the Company in its various business units and are in various stages of maturity.

Our Customers

DTI, our wholly owned subsidiary, operates our Intelligent Technologies Division which develops and implements an array of sophisticated, proprietary technology applications and turnkey engineered systems. Initially developed and deployed for homeland and border security, these applications have been or are currently used by 5 of North American’s 7 major freight rail operators (known as Class-1), such as Canadian National (CN), Union Pacific (UP), CSX, Burlington Northern Santa Fe (BNFS), Kansas City Southern (KCS), as well as Mexico’s largest freight rail operator, Ferromex. After achieving initial success in the transportation industry, the Company broadened its market reach, adapting its proprietary technologies to a suite of applications now servicing the commercial, industrial, utilities and government sectors. Our current major customers include Amtrak, BNSF, CN, Concho Oil, Conrail, CSX, Chicago Metra, Metrolink, Kansas City Southern de Mexico (KCSM), Ferromex, Kohl’s, Olin Chemical, TTCI and Union Pacific.

Additionally, our IT Asset Management (“ITAM”) division provides infrastructure and device audit services for large data centers. The ITAM division released a new software platform, dcVue which significantly automates the collection and audit of IT assets within data centers.  The new software was beta tested in late 2018 at a major customer and is scheduled to be released as a licensed product starting the second quarter of the 2019 fiscal year. The new software can be used both by the ITAM division for services and as a standalone product where clients desire to manage their own IT assets audits. The Company markets its ITAM services through strategic partners.

The ultimate goal is to provide our end users with improved situational awareness and overall efficiencies in operations by leveraging “smart” technology as a force multiplier. Our current core technology solutions are industry agnostic and suitable for adaptation to a wide range of applications and industries.

Market

Currently, our target market is North America and we expect to soon expand globally through strategic partnerships. The majority of our customers are Fortune 100 and 500 companies with a focus on the $60B North American Rail market, the $2B video analytics market and the $53B enterprise information systems market. The addition of our dedicated AI subsidiary expands our target market by $9.5 billion by 2022 (Source: IDC, Forrester and Think Equity estimates). We originally implemented our products in railcar security inspection with a focus on providing our customers with the capability of performing mission critical security inspections of inbound trains crossing US/Mexican borders from a centralized, remote location. The U.S. Customs and Border Protection (“CBP”) agency uses our systems at critical border rail crossings. Over the last three years we have developed new systems based on this original technology to greatly expand our business by offering mission critical mechanical and safety inspection systems with the goal of improving operational efficiency.  Many opportunities exist within this operating environment.  Our initial emphasis on freight carriers by providing mechanical inspection portals for the remote inspection of railcars while traveling at high speeds has had a significant positive impact on our revenue. Unlike trucks, barges and airlines; freight railroads operate almost exclusively on infrastructure that they own, build and maintain. According to the AAR article on Freight Railroad Capacity and Investment dated April 2016, from 1980 to 2015 freight railroads alone reinvested approximately $600 billion of their own funds in capital expenditures and maintenance projects related to locomotives, freight cars, tracks, bridges, tunnels and other infrastructure related equipment. The AAR further reports that more than 40 cents out of every revenue dollar is reinvested into a rail network.

According to AAR’s statistical railroad report, there are approximately 1.56 million freight cars and 26,574 locomotives in service operated on approximately 250,000 miles of active rail tracks throughout North America. Rail tracks are predominantly owned by the Class-I railroad industry which include:

The report further elaborates that profitability of rail operators is measured by their operating ratio, which is the rail operator’s operating expense as a percentage of revenue. According to AAR’s Annual Spending Data report, the labor cost to run and maintain trains represent a significant portion of their total operating expenses. Revenue is mostly affected by the average “velocity” of its rolling stock, which determines how much freight or how many passengers a rail operator can transport between destinations and the average speeds. Railroads implement their own speed limits within Federal Railroad Administration (FRA) guidelines. Average speed is impacted by many factors including, but not limited to:

·

Track curvatures and condition, signaling, and stoppages for inspections (security and mechanical);

·

Grade crossings; and

·

Physical condition of locomotives and railcars.

Freight trains are considered massive in size and weight. Thus, worn or broken parts can have a significantly negative impact on operations. Quicker detection can prevent costly car and track repairs, and derailments. Early detection has the potential to dramatically increase velocity and direct profitability.

Examples include inspections at rail border crossings by CBP agents, which can often lead to significant delays and mandated mechanical inspections. Under FRA regulations, each time a railcar departs a yard, terminal or industrial facility, it is required to be inspected by either a qualified mechanical inspector or a train crew member for specific defects that would adversely affect the safe operation of the train. There are currently over 70 mechanical and safety inspection criteria, therefore the inspection process typically takes between two and three hours (dwell time) during which each train is “grounded” in a maintenance yard. In addition, the current railcar inspection process is tedious, labor intensive, dangerous and in general, lacks the level of efficiency and objectivity that may be achievable using technology.

4

To effectively detect structural or mechanical defects, railcar inspectors today need to walk around the car and under current practice, they are unable to inspect undercarriage components. Because this process is so lengthy and hazardous, it is only utilized for pre-departure mechanical inspections. Otherwise, cars are only inspected with this level of scrutiny in shops before undergoing major repairs. In addition to the inherent safety and efficiency challenges of manual inspections, records of these inspections are generally not retained unless a billed repair is performed. Thus, the maintenance of railcar structural components is almost entirely reactive rather than predictive, making repairs and maintenance less efficient.

For many years, the rail industry, through the AAR and its subsidiary TTCI, has been evaluating the feasibility of using technology, and has most recently focused on the objective of performing remote mechanical inspections prior to a train arriving at a rail yard. In the first phase, car inspectors would remotely perform visual inspections of multiple train “consists”, a group of rail vehicles which are permanently or semi-permanently coupled together to form a unified set of equipment, from a regional inspection station and generate work orders for detected anomalies. These anomalies will be distributed to the respective yards prior to a train arriving at the yard facility. The time-consuming process of physical inspection would be significantly reduced, leading to a significant increase in average velocity and decreased labor cost. We believe this lends itself to the natural progression of automating the inspection process, taking inspectors from the physical inspection to the required actions for diagnosing and resolving issues.

We are currently in the process of converting the inspection process to a complete automated system that will inspect entire trains via an “intelligent system”. Our technology creates the platform to implementing a wayside inspection portal employing a combination of sensors capturing live images and sensor data, of each side, top and undercarriage of each locomotive and rail car. Software algorithms interpret the data to identify defects or anomalies. The industry expects to increase average speed and consequently overall return on investment due to the following:

1.

The safety risks associated with manual car inspection will be minimized through reduced exposure to potential yard hazards; and

2.

Reducing inspection time will increase yard efficiency and improve overall network capacity by also reducing the time needed to process inbound and outbound trains.

We believe that the evolution of automating the inspection processes is broadly advocated throughout the industry. In our experience, the freight rail companies are constantly seeking out innovative ways to increase capacity and improve efficiencies while increasing safety and security standards. A recently launched aggressive plan to automate the mechanical inspection process is at the core of our market opportunity.

Our Products and Systems - Technology Platforms

The Company’s technology architecture used in the majority of our solutions is comprised of two core technology platforms i.e. praesidium® and centraco®.

These proprietary software suites are distributed as licensed software and form the centerpiece of our engineered turnkey systems. Each integrated sub-system encompasses three major components:

1.

The data collectors, including specialized cameras integrated by the Company and other sensors that are specific to the customers’ requirements (third party supplied or pre-existing);

2.

 praesidium®, the analytics software suite which performs real-time analysis of the data generated by the Company; and

3.

centraco®, the multi-layered presentation interface which graphically depicts the data analyzed and identifies anomalies and provides actionable intelligence.

Since inception, we have developed and patented key software components that provide a significant competitive advantage in specialized solutions for our target markets. We believe an important factor in this development is that the Company’s intellectual property is “industry agnostic” and can be deployed to many different industries. The following technical descriptions of praesidium® and centraco® provide further insight.  In late 2018, we took the decision to expand our offerings and launch a new subsidiary, TrueVue360, with the aim of focusing on artificial intelligence (AI), deep machine learning and advanced algorithm development.  Many of these capabilities already existed within the Company’s R&D team and TrueVue360’s mission is to significantly expand and to further enhance those offerings into the market, both within our traditional market space as well as new markets.

praesidium® Intelligent Analytics Suite

praesidium® is an integrated suite of analytics applications which processes and analyzes data streams from a virtually unlimited number of conventional or specialized sensors and/or data points. Our algorithms compare analyzed data against user-defined criteria and rules in real time and automatically reports any exceptions, deviations and/or anomalies. This application suite also includes a broad range of conventional operational system components and sub-systems, including an embedded feature-rich video management engine and a proprietary Alarm Management Service (“AMS”). The AMS provides continuous monitoring of all connected devices, processes, equipment and sub-systems, and automatically communicates to centraco®, the Company’s enterprise information management suite if and when an issue, event or performance anomaly is detected. The processed information is instantly distributed simultaneously to an unlimited number of users in a visualized and correlated user interface using the centraco® command and control platform.

Our core modules are tailored to specific industry applications and the analytics engine(s) process any type of conventional sensor outputs, also adding “intelligence” to any third-party sensor technology. A key benefit is that the customer may often retain existing systems and we would integrate these into an overall solution.

Not a complete representation of the praesidium® modules.

As listed on the Safetyact.gov website, the praesidium® video analytics technology has received “Safety Act” designation from the US Department of Homeland Security. To our knowledge, we are one of only ten companies to have received this designation for video related solutions and praesidium® is the only video analytics application with this designation.

Over the years, our proprietary analytics suite has been expanded to meet a significant number of security objectives and environments, adaptable to a broad range of critical infrastructure target verticals, including but not limited to, commercial transportation (rail, air and seaports), retail, healthcare, utilities, oil, gas, chemical and government.

centraco® Enterprise Command and Control Suite

centraco® is an Enterprise Information Management (EIM) system. It was designed as a multi-layered command and control interface and to function as the central point and aggregator for information consolidation, connectivity and communications. The platform is browser based and completely agnostic to the interconnected sub-systems. It provides full LDAP (Lightweight Directory Access Protocol, also known as Active Directory) integration for seamless user credentialing and performs the following major functions:

Engineered Solutions

The Company has always delivered engineered solutions which translate into the ability to implement a practical solution to specific customer requirements. Often, software is developed where implementation is the responsibility of the customer. We believe that delivering and supporting turnkey working systems that provide measurable end solutions are the preferred business model for our customers. We also believe that any implementation must co-exist in an already functioning operation and that any solution must work within existing business practices. Due to this philosophy, over time, our code base has been expanded to integrate a myriad of third-party sensor technologies thereby creating complete engineered solutions that dovetail into existing environments and thus not forcing our customers to replace working legacy systems. These engineered solutions usually address more complex end-user requirements and are typically designed, developed, deployed and maintained by the Company in a direct relationship with the end-user on a turnkey basis.

The combination of our two platforms (praesidium® and centraco®), with its many variants, has and continues to deliver comprehensive “end-to-end” solutions, some of which already play a significant role in pro-active homeland security including cross border commercial rail transport.

More recently, we created several proprietary, turnkey systems and applications for commercial railways, the most significant being the following:

7

Intelligent Rail Inspection Portal (rip™)

This turnkey system was originally designed for rail security and inspection at rail border crossings. Under a Union Pacific (UP) funded pilot program the Company designed, developed and deployed an intelligent inspection portal to provide the CBP a tool that aids customs officers in the inspection of inbound and outbound railcars. The rip^™ system uses multiple proprietary technologies and sub-systems to remotely scan all railcars passing through the inspection portal, then displays stitched 360-degree views of the entire rail “consist”.

Users conduct a quick review of the pre-screened imagery and decide whether to refer specific areas of interest to field personnel for further (physical) inspection.

Panoramic View of Stitched Train Consists – Security Application

Using sensors and analytical algorithms, we pre-screen railcars and automatically detect and report anomalies and deviations from established norms. After successfully passing rigorous testing this system has now been adopted into the CBP standard concept of operation for southwestern rail border crossings and has been deployed at southwestern border locations, with a few remaining locations currently under negotiation. Similar systems have been deployed to two (undisclosed) locations in Mexico and are currently monitored by the Mexican subsidiary of Kansas City Southern (KCS).

Modified Application for Remote Mechanical Inspection at High Speed

Truck Springs Geometry – Simultaneously Measured on Opposing Sides of Car at High Speed

9

Automatic Detection of Missing Bolt at High Speed

The development and field-testing of the core application were completed successfully during the third quarter of the 2016 fiscal year. After an extensive Request for Proposal (“RFP”) process, we received a contract award in early 2016 to deploy our technology at a live site from CSX Transportation, one of North America’s Class I railroads. The award is a “real-time test run” in anticipation of adapting our technology as a process standard. We received a similar award from Ferromex, Mexico’s largest rail operator mid-year 2016. Both systems were completed, delivered, and the Ferromex system is currently in production.  In addition, CN, one of the largest North American freight carriers, ordered seven new rail inspection portals of which four are in operation and undergoing acceptance testing with the additional three expected to be deployed in the first six months of 2019.

Our rip™ application provides the following modules for automated analysis, detection and inspection:

·

Linear Panorama Generator;

·

Automated Detection of Open Doors;

·

Automated Detection of Open/Missing Hatches;

·

Train Rider Detection System (trids™);

·

Under Vehicle Inspection with Foreign Object Detection (vue™);

·

Gondola Car Inspection System;

·

Pantograph Inspection System (apis™); and

·

3D modeling using LIDAR technology for Transit platform intrusion detection (under development).

We were commissioned in 2018 to develop a further 10 algorithmic detection modules for automatic discovery of additional anomalies.  These are expected to be operational in 2019 and will be further enhanced using the truevue360 development platform.  

Utilizing the centraco® command and control platform as the system interface, the user accesses a variety of features enabling remote inspection, analysis and detection from the safety of remote command centers. Images containing detailed views of areas of concern, determined to be “potentially suspicious”, are automatically presented to a human operator for further inspection. Users conduct a quick review of the pre-screened imagery and decide whether to refer specific areas of interest to field personnel for further (physical) inspection and/or repair.

The system also resolves the particularly difficult process of inspecting railcar undercarriages by providing high resolution images of the entire undercarriage. The system is designed to help streamline the physical inspection process by narrowing the number of inspection targets down to cars with “potential” anomalies. Consequently, the detection sensitivity is intentionally set to err on the safe side to avoid false negatives. Our customers are in the process of awarding the development of a significant number of detection algorithms, which combined with our Inspection Portal technology, will eventually facilitate full automation of the mechanical inspection process. We believe we are well positioned to capture a significant portion of this phase of the automation process.

We also adapted our inspection portal technology to the retail industry and have recently deployed a complete gatehouse automation system with a national footprint for Kohl’s department stores to automate in and outbound traffic controls at their nine distribution centers. The systems were deployed in 2018 and are now operational.

We received an award from the New York City Transit (NYCT) to develop a pilot system using our intelligent technology to automatically detect intrusions to their passenger platform tracks. NYCT plans to deploy technology to their 470+ transit stations to minimize derailments caused by objects falling onto their tracks. We participated in multiple proof of concept trials during 2018 and we continue to further refine and develop our offerings and continue to work with NYCT’s governing agency, the Metropolitan Transportation Authority (MTA) to further progress this large potential contract.

We also received an award from a large regional bank with a national footprint for the implementation of headquarters and branch security at 19 locations using our intelligent technology platforms.  This project contributed to revenue during 2018 with the majority of revenues expected to be recorded in 2019.

IT Asset Management

Our IT Asset Management (ITAM) division is dedicated to the mission of developing, marketing and delivering software and professional services to the world’s largest data centers. The focus of its technology and knowledgebase evolved out of our core strength in collecting and analyzing data on assets resident within these large data centers. Over the next three years, the Company plans to further develop its software and service offerings, and market these solutions for the growing ITAM market place either as a standalone asset management solution or in conjunction with comprehensive Datacenter Infrastructure Management (DCIM) solutions from other vendors. Our ITAM offerings give the ability to bridge the gap between critical IT assets and facilities infrastructure.

Using proprietary patented methodology, the Company surveys and audits large data centers by physically identifying each piece of equipment and its location. By scanning all devices into our proprietary system and providing the client with a report detailing type, quantity and location of its IT assets, (racks, servers, network cards, power supplies, etc.), this system/service provides our clients with the ability to verify their own internal records.

In 2018 we released a new software platform, dcVue, a newly developed software application for use by the Company’s services professionals to do data collection and auditing at the largest data centers.  The product was in beta testing throughout the latter half of 2018 and is scheduled to be marketed as a licensed product starting in the second quarter of the 2019 fiscal year.

In line with the Company’s philosophy of integration with existing systems, the design of our process methodology and related software mean that we are able to work with almost any other DCIM provider. Specifically, the Company will focus on the asset management requirements of our clients and partners within specific geographic locations that will allow the Company to balance its investment requirements with income potential to develop a sustainable business in this division. The Company has selected this specific application of its technology to seek revenue opportunities that are readily available in an identified market. We generate profits from this division by maintaining a low level of “bench” staff and hire independent consultants as we are awarded business opportunities. We expect that this will generate revenues from software sales and maintenance starting in Q2 2019.

Specific Areas Of Competition

Since inception, we have implemented a strategy of diversification to mitigate the potential vulnerabilities experienced by companies with a narrow business scope. We believe many public companies in the micro- and nano-cap ecosystem suffer major challenges due to their lack of diversification, and their single product strategy has made many of these companies irrelevant in the market place.

During the past several years, we have made considerable investments in, and have successfully developed, our two core technology platforms, praesidium® and centraco®.

praesidium® is an open architecture, modular engine that manages an unlimited number of “back end” process and analytics frameworks. In addition to driving our own proprietary sensor and data analytics, this core technology also allows for the integration of an unlimited number of third-party technologies, systems and sub-systems. Third-party industry or task-specific processes are modularized and embedded into the praesidium® engine, thereby substantially expanding the functionality of such third-party system. While we believe most companies tailor their products and services to a specific industry, this core platform is “industry agnostic” which we believe will allow us to penetrate multiple industries. Our past and current concentration on specific target markets such as rail, retail, healthcare, utilities, chemical, gas, oil and government has enabled us to test the markets with our innovative technology solutions. Our praesidium® platform competes currently with the following sector specific companies:

11

(1)

We believe we are the first to develop the concept of an intelligent rail inspection portal used for comprehensive inspection of security threads and at this time we are unaware of any competitor in this sector. Recently, the AAR, through its technology research subsidiary TTCI, has engaged us to adapt our security portal technology to an automated mechanical inspection system. We are currently in stage 2 of 3 of this development. We believe our potential competitors in this area are currently focusing chiefly on the inspection of wheels, bearings, breaks and track alignment. We expect that any competitor interested in expanding their inspection technologies to the ones we have developed over the past four years would require at least 2-3 years of research and development before being able to produce similar systems for real time testing. We believe the testing cycle will take at least an additional 1-2 years for potential competition. The AAR/TTCI is currently conducting beta testing only with our systems. Similarly, the CBP (US Customs and Border Protection) and Union Pacific Railroad are using our systems as their only security inspection infrastructure at the US border.

centraco® is an open architecture aggregator and “fusion” engine which functions as a comprehensive “front end” user interface. This framework combines our proprietary modules with an unlimited number of 3rd-party technologies. In addition to a wide range of proprietary embedded features, such as video management (VMS), alarm management (AMS), LDAP network access credentialing and many more, centraco® intelligently manages unlimited types of data sources and allows control and monitoring of this wide array of sensors and data from a single unified interface. This platform includes both the traditional Physical Security Information Management (PSIM) systems, as well as, a full-scale Enterprise Information Management System (EIMS). We believe we are at an advantage because none of our competitors’ product offerings include both PSIM and EIMS, nor do any of the competing products allow for the integration of embedded engineered solutions. Our competitors in this area include:

We believe the PSIM market is rapidly expanding and we expect that capability requirements will substantially increase. Companies increasingly require expanded capabilities to justify the investment in their digital infrastructure for use by multiple corporate disciplines (security, building management, IT and network access control management).

Our Growth Strategy

Our strategy is to grow our business through a combination of organic growth of our applications and technology solutions, both within our existing geographic reach and through geographic expansion, as well as expansion through strategic acquisitions.

Organic Growth

Our organic growth strategy is to increase our market share through the expansion of our business development team and our research and development talent pool, which will enable us to significantly expand our current solution offerings with feature rich applications, and the development of new and enhanced technology solutions. We plan to augment such growth with strategic relationships both in the business development and research development arenas, reducing time to market with additional industry applications, expansion of existing offerings to meet customer requirements, as well as, potential geographical expansion into international territories.  The launch of our AI software systems through our TrueVue360 subsidiary is another building block of this strategy.

Strategic Acquisitions

Planned acquisition targets include sector specific technology companies with the objective of augmenting our current capabilities with feature-rich (third-party) solutions. The decision-making process includes, but is not limited to, weighing time, effort and approximate cost to develop certain technologies in-house, versus acquiring or merging with one or more entities that we believe have a proven record of successfully developing a technology sub-component. Additional criteria include evaluating the potential acquisition target’s customer base, stage of technology and merger or acquisition cost as compared to market conditions.

12

Manufacturing and Assembly

The Company streamlines its manufacturing by outsourcing component manufacturing to qualified fabricators. On-site installations are performed using a combination of in-house project managers/engineers and specialist sub-contractors as necessary. We maintain responsibility for the system implementation, servicing and tech support for our solutions. Our internal manufacturing operations consist primarily of materials procurement, assembly, testing and quality control of our engineers. If not manufactured internally, we generally rely on third party manufacturing partners to produce our hardware related components and hardware products and we may involve our internal manufacturing operations in the final assembly, testing and quality control processes for these components and products. We distribute most of our hardware products either from our facilities or partner facilities. Our manufacturing processes are based on standardization of components across product types, centralization of assembly and distribution centers, and a “build-to-order” methodology in which products generally are built only after customers have placed firm orders. For most of our hardware products, we have existing alternate sources of supply or such sources are readily available.

Research and Development

The Company’s R&D and software development teams design and develop all systems and software applications with a combination of full-time in-house software engineers and full-time contractors. Internal development allows us to maintain technical control over the design and development of our products. We have several United States and foreign patents and patent-pending applications that relate to various aspects of our products and technology. Rapid technological advances in hardware and software development, evolving standards in computer hardware and software technology, and changing customer requirements characterize the markets in which we compete. We plan to continue to dedicate significant resources to research and development efforts, including software development, to maintain and improve our current product and services offerings.  In late 2018, we increased our expenditures on R&D staffing in anticipation of the launch of our AI software systems through TrueVue360.

Government Regulations

The Company has been working with various agencies of the federal government for more than 10-years including the Department of Homeland Security (“DHS”). Our video analytics are DHS “Safety Act” certified, and the majority of our staff is Chemical Facility Anti-Terrorism Standards (CFATS) certified. The Company’s Homeland Security solutions include sophisticated remote systems that combine and synchronize a myriad of sensing technologies, wireless communications, and innovative intelligent sensor applications.

Intellectual Property

Our business is significantly based on the creation, acquisition, use and protection of intellectual property. Some of this intellectual property is in the form of software code, patented technology and trade secrets that we use to develop our technologies, solutions and products. We have developed a broad portfolio of intellectual property that covers our application software as well as the sensor and data acquisition process of our security and inspection analytics platforms. During 2018 we were granted a new patent for our Linear Speed Sensor and as of December 31, 2018, we now have 10 patents and 20 trademarks issued or granted by the United States Patent and Trademark Office (USPTO) and we have 1 pending patent application with the USPTO.

We protect our intellectual property rights by relying on federal, state and common law rights, as well as contractual restrictions. We control access to our proprietary technology by entering into confidentiality and invention assignment agreements with our employees and contractors, and confidentiality agreements with third parties. We also actively engage in monitoring activities with respect to infringing uses of our intellectual property by third parties.

In addition to these contractual arrangements, we also rely on a combination of trade secret, copyright, trademark, trade dress, domain name and patents to protect our products and other intellectual property. We typically own the copyright to our software code, as well as the brand or title name trademark under which our products are marketed. We pursue the registration of our domain names, trademarks, and service marks in the United States and in locations outside the United States.

As discussed in the risk factors section herein, we may face allegations by third parties, including our competitors and non-practicing entities, that we have infringed their trademarks, copyrights, patents and other intellectual property rights.

13

Employees

We have a current staff of 55 employees, the majority of which work in the Jacksonville area, none of which are subject to a collective bargaining agreement. We have not experienced any work stoppages and we consider our relationship with our employees to be good.

RISK FACTORS

Investing in our securities involves a great deal of risk. Careful consideration should be made of the following factors as well as other information included in this prospectus before deciding to purchase our securities. There are many risks that affect our business and results of operations, some of which are beyond our control. Our business, financial condition or operating results could be materially harmed by any of these risks. This could cause the trading price of our securities to decline, and you may lose all or part of your investment. Additional risks that we do not yet know of or that we currently think are immaterial may also affect our business and results of operations.

Risks Related to Our Company and Business

Our auditor has expressed substantial doubt regarding our ability to continue as a going concern.

We had a net loss of $1,580,887 for the year ended December 31, 2018. During the same period, cash used in operations was $345,287. The accumulated deficit as of December 31, 2018 was $30,269,833. Although our financial condition has improved substantially, our auditor has expressed substantial doubt regarding our ability to continue as a going concern. Management is unable to predict if and when we will be able to consistently generate positive cash flow. Our plan regarding these matters is to focus our efforts on continued substantial revenue growth through investments in sales and marketing and project execution staff. Although these investments are expected to allow us the ability to cover our current cash flow requirements and meet our obligations as they become due, there can be no assurances that these investments will generate the additional revenues needed to cover our obligations.

The nature of the technology management platforms utilized by us are complex and highly integrated, and if we fail to successfully manage releases or integrate new solutions, it could harm our revenues, operating income, and reputation.

The technology platforms developed and designed by us accommodate integrated applications that include our own developed technology and third-party technology, thereby substantially increasing their functionality. By enabling such system interoperability, our communications platform both reduces implementation and ongoing costs, and improves overall management efficiencies.

Due to this complexity and the condensed development cycles under which we operate, we may experience errors in our software, corruption or loss of our data, or unexpected performance issues from time to time. For example, our solutions may face interoperability difficulties with software operating systems or programs being used by our customers, or new releases, upgrades, fixes or the integration of acquired technologies may have unanticipated consequences on the operation and performance of our other solutions. If we encounter integration challenges or discover errors in our solutions late in our development cycle, it may cause us to delay our launch dates. Any major integration or interoperability issues or launch delays could have a material adverse effect on our revenues, operating income and reputation.

Our products and services may fail to keep pace with rapidly changing technology and evolving industry standards.

The market in which we operate is characterized by rapid, and sometimes disruptive, technological developments, evolving industry standards, frequent new product introductions and enhancements and changes in customer requirements. In addition, both traditional and new competitors are investing heavily in our market areas and competing for customers. As next-generation video analytics technology continues to evolve, we must keep pace in order to maintain or expand our market position. We recently introduced a significant number of new product offerings and are increasingly focused on new, high value safety and security-based surveillance products, as a revenue driver. If we are not able to successfully add staff resources with sufficient technical skills to develop and bring these new products to market in a timely manner, achieve market acceptance of our products and services or identify new market opportunities for our products and services, our business and results of operations may be materially and adversely affected.

The market opportunity for our products and services may not develop in the ways that we anticipate.

The demand for our products and services can change quickly and in ways that we may not anticipate because the market in which we operate is characterized by rapid, and sometimes disruptive, technological developments, evolving industry standards, frequent new product introductions and enhancements, changes in customer requirements and a limited ability to accurately forecast future customer orders. Our operating results may be adversely affected if the market opportunity for our products and services does not develop in the ways that we anticipate or if other technologies become more accepted or standard in our industry or disrupt our technology platforms.

23

Our revenues are dependent on general economic conditions and the willingness of enterprises to invest in technology.

We believe that enterprises continue to be cautious about sustained economic growth and have tried to maintain or improve profitability through cost control and constrained spending. While our core technologies are designed to address cost reduction, other factors may cause delaying or rejecting capital projects, including the implementation of our products and services. In addition, certain industries in which we operate are under financial pressure to reduce capital investment which may make it more difficult for us to close large contracts in the immediate future. We believe there is a growing market trend toward more customers exploring operating expense models as opposed to capital expense models for procuring technology. We believe the market trend toward operating expense models will continue as customers seek ways of reducing their overhead and other costs. All of the foregoing may result in continued pressure on our ability to increase our revenue and may potentially create competitive pricing pressures and price erosion. If these or other conditions limit our ability to grow revenue or cause our revenue to decline our operating results may be materially and adversely affected.

We could be vulnerable to security breaches if certain third-parties attempt to gain access through our systems because of unknown weaknesses in our clients’ infrastructures.

Our systems operate inside client network infrastructure, which typically reside behind an ASA or other form of firewall. Communication between us and our clients are highly encrypted and generally take place through virtual private network (VPN) connections. We also use ASA equipment to protect our own network infrastructure. In addition, although our systems are LDAP/Active Directory compatible and include additional security layers we cannot be assured that any of our or our client’s systems are 100% secure. Any breach of these systems could be damaging to our reputation and lead to a loss of confidence in our offerings. Such loss of confidence could impact future sales or revenues from existing systems.

Some of our competitors are larger and have greater financial and other resources than we do.

Some of our product offerings compete and will compete with other similar products from our competitors. These competitive products could be marketed by well-established, successful companies that possess greater financial, marketing, distributional, personnel and other resources than we possess. In certain instances, competitors with greater financial resources also may be able to enter a market in direct competition with us offering attractive marketing tools to encourage the sale of products that compete with our products or present cost features that our target end users may find attractive.

We have a history of losses and our growth plans expect to incur losses and negative operating cash flows in the future.

Our accumulated deficit was approximately $30 million as of December 31, 2018. Our operating losses may continue as we continue to expend resources to further develop and enhance our technology offering, to complete prototyping for proof-of-concept, obtain regulatory clearances or approvals as required, expand our business development activities and finance capabilities and conduct further research and development. We also expect to experience negative cash flow in the short-term until our revenues and margins increase at a rate greater than our expenses which will continue to grow as we invest in additional resources for development and sales.

Our inability to protect our intellectual property could impair our competitive advantage, reduce our revenue, and increase our costs.

Our success and ability to compete depend in part on our ability to maintain the proprietary aspects of our technologies and products. We rely on a combination of trade secrets, patents, copyrights, trademarks, confidentiality agreements, and other contractual provisions to protect our intellectual property, but these measures may provide only limited protection. We customarily enter into written confidentiality and non-disclosure agreements with our employees, consultants, customers, manufacturers, and other recipients of information about our technologies and products and assignment of invention agreements with our employees and consultants. We may not always be able to enforce these agreements and may fail to enter into any such agreement in every instance when appropriate. We license from third party’s certain technology used in and for our products. These third-party licenses are granted with restrictions; therefore, such third-party technology may not remain available to us on terms beneficial to us. Our failure to enforce and protect our intellectual property rights or obtain from third parties the right to use necessary technology could have a material adverse effect on our business, operating results, and financial condition. In addition, the laws of some foreign countries do not protect proprietary rights as fully as do the laws of the United States.

24

Patents may not issue from the patent applications that we have filed or may file in the future. Our issued patents may be challenged, invalidated, or circumvented, and claims of our patents may not be of sufficient scope or strength, or issued in the proper geographic regions, to provide meaningful protection or any commercial advantage. We have registered certain of our trademarks in the United States and other countries. We cannot assure you that we will obtain registrations of principal or other trademarks in key markets in the future. Failure to obtain registrations could compromise our ability to protect fully our trademarks and brands and could increase the risk of challenge from third parties to our use of our trademarks and brands.

We may be required to incur expenses and divert management attention and resources in defending intellectual property litigation against us.

We cannot be certain that our technologies and products do not and will not infringe on issued patents or other proprietary rights of others. While we are not currently subject to any infringement claim, any future claim, with or without merit, could result in significant litigation costs and diversion of resources, including the attention of management, and could require us to enter into royalty and licensing agreements, any of which could have a material adverse effect on our business. We may not be able to obtain such licenses on commercially reasonable terms, if at all, or the terms of any offered licenses may be unacceptable to us. If forced to cease using such technology, we may be unable to develop or obtain alternate technology. Accordingly, an adverse determination in a judicial or administrative proceeding, or failure to obtain necessary licenses, could prevent us from manufacturing, using, or selling certain of our products, which could have a material adverse effect on our business, operating results, and financial condition.

Furthermore, parties making such claims could secure a judgment awarding substantial damages, as well as injunctive or other equitable relief, which could effectively block our ability to make, use, or sell our products in the United States or abroad. Such a judgment could have a material adverse effect on our business, operating results, and financial condition. In addition, we are obligated under certain agreements to indemnify the other party in connection with infringement by us of the proprietary rights of third parties. In the event that we are required to indemnify parties under these agreements, it could have a material adverse effect on our business, financial condition, and results of operations.

We may incur expenses and divert management resources in prosecuting others for their unauthorized use of our intellectual property rights.

Other companies, including our competitors, may develop technologies that are similar or superior to our technologies, duplicate our technologies, or design around our patents, and may have or obtain patents or other proprietary rights that would prevent, limit, or interfere with our ability to make, use, or sell our products. Although we do not have foreign operations at this time, we may compete for contracts in non-US countries from time to time. Effective intellectual property protection may be unavailable, or limited, in some foreign countries in which we may do business, such as China. Unauthorized parties may attempt to copy or otherwise use aspects of our technologies and products that we regard as proprietary. Our means of protecting our proprietary rights in the United States or abroad may not be adequate or competitors may independently develop similar technologies. If our intellectual property protection is insufficient to protect our intellectual property rights, we could face increased competition in the market for our technologies and products.

Should any of our competitors file patent applications or obtain patents that claim inventions also claimed by us, we may choose to participate in an interference proceeding to determine the right to a patent for these inventions, because our business would be harmed if we fail to enforce and protect our intellectual property rights. Even if the outcome is favorable, this proceeding could result in substantial cost to us and disrupt our business.

In the future, we also may need to file lawsuits to enforce our intellectual property rights, to protect our trade secrets, or to determine the validity and scope of the proprietary rights of others. This litigation, whether successful or unsuccessful, could result in substantial costs and diversion of resources, which could have a material adverse effect on our business, financial condition, and results of operations.

25

If we are unable to apply technology effectively in driving value for our clients through technology-based solutions or gain internal efficiencies and effective internal controls through the application of technology and related tools, our operating results, client relationships, growth and compliance programs could be adversely affected.

Our future success depends, in part, on our ability to anticipate and respond effectively to the threat and opportunity presented by digital disruption and developments in technology. These may include new software applications or related services based on artificial intelligence, machine learning, or robotics. We may be exposed to competitive risks related to the adoption and application of new technologies by established market participants (for example, through disintermediation) or new entrants, start-up companies and others. These new entrants are focused on using technology and innovation, including artificial intelligence to simplify and improve the client experience, increase efficiencies, alter business models and effect other potentially disruptive changes in the industries in which we operate. We must also develop and implement technology solutions and technical expertise among our employees that anticipate and keep pace with rapid and continuing changes in technology, industry standards, client preferences and internal control standards. We may not be successful in anticipating or responding to these developments on a timely and cost-effective basis and our ideas may not be accepted in the marketplace. Additionally, the effort to gain technological expertise and develop new technologies in our business requires us to incur significant expenses. If we cannot offer new technologies as quickly as our competitors, or if our competitors develop more cost-effective technologies or product offerings, we could experience a material adverse effect on our operating results, client relationships, growth and compliance programs.

We are dependent on information technology networks and systems to securely process, transmit and store electronic information and to communicate among our locations around the world and with our people, clients, partners and vendors. As the breadth and complexity of this infrastructure continues to grow, including as a result of the use of mobile technologies, social media and cloud-based services, the risk of security breaches and cyberattacks increases. Such breaches could lead to shutdowns or disruptions of or damage to our systems and those of our clients, alliance partners and vendors, and unauthorized disclosure of sensitive or confidential information, including personal data. In the past, we have experienced data security breaches resulting from unauthorized access to our and our service providers’ systems, which to date have not had a material impact on our operations; however, there is no assurance that such impacts will not be material in the future.

In providing services and solutions to clients, we often manage, utilize and store sensitive or confidential client data, including personal data, and we expect these activities to increase, including through the use of artificial intelligence, the internet of things and analytics. Unauthorized disclosure of sensitive or confidential client data, whether through systems failure, employee negligence, fraud, misappropriation, or other intentional or unintentional acts, could damage our reputation, cause us to lose clients and could result in significant financial exposure. Similarly, unauthorized access to our or through our or our service providers’ information systems or those we develop for our clients, whether by our employees or third parties, including a cyberattack by computer programmers, hackers, members of organized crime and/or state-sponsored organizations, who continuously develop and deploy viruses, ransomware or other malicious software programs or social engineering attacks, could result in negative publicity, significant remediation costs, legal liability, damage to our reputation and government sanctions and could have a material adverse effect on our results of operations. Cybersecurity threats are constantly expanding and evolving, thereby increasing the difficulty of detecting and defending against them and maintaining effective security measures and protocols.

We depend on key personnel who would be difficult to replace, and our business plan will likely be harmed if we lose their services or cannot hire additional qualified personnel.

Our success depends substantially on the efforts and abilities of our senior management and certain key personnel. The competition for qualified management and key personnel, especially engineers, is intense. Although we maintain non-competition and non-disclosure covenants with all our key personnel, we do not have employment agreements with most of them. The loss of services of one or more of our key employees, or the inability to hire, train, and retain key personnel, especially engineers and technical support personnel, could delay the development and sale of our products, disrupt our business, and interfere with our ability to execute our business plan.

Due to our dependence on a limited number of customers, we are subject to a concentration of credit risk.

As of December 31, 2018, two customers accounted for 92% of our accounts receivable. In the case of insolvency by one of our significant customers, accounts receivable with respect to that customer might not be collectible, might not be fully collectible, or might be collectible over longer than normal terms, each of which could adversely affect our financial position. Additionally, our two largest customers accounted for approximately 83% of our total revenues for the year ended December 31, 2018. This concentration of credit risk makes us more vulnerable economically. The loss of any of these customers could materially reduce our revenues and net income, which could have a material adverse effect on our business.

26

Potential strategic alliances may not achieve their objectives, and the failure to do so could impede our growth.

We may enter into strategic alliances. Among other matters, we continually explore strategic alliances designed to enhance or complement our technology or to work in conjunction with our technology; to provide necessary know-how, components, or supplies; to attract additional customers; and to develop, introduce, and distribute products utilizing our technology. Any strategic alliances may not achieve their intended objectives, and parties to our strategic alliances may not perform as contemplated. The failure of these alliances may impede our ability to introduce new products.

The Company owes the IRS penalty payments in connection with the delinquent payment of payroll taxes.

As of the date hereof, the Company has paid its payroll taxes in full and the Company had appealed the IRS penalty payments for a reduction which was under review. The IRS has since responded, and the Company will be required to repay the penalties in connection with the delinquent payroll taxes. At December 31, 2018, the payroll taxes payable balance of $317,573 includes accrued late fees in the amount of $123,572. The Company is making monthly payments in the amount of $15,000 to pay down the accrued late fees.

Risks Related to Our Common Stock

There is currently not an active liquid trading market for the Company’s common stock.

Our common stock is quoted on the OTC Markets QB tier under the symbol “DUOT”. However, there is currently no regular active trading market in our common stock. Although there are periodic volume spikes from time to time, we cannot give an assurance that a consistent, active trading market will develop in the short term. If an active market for our common stock develops, there is a significant risk that our stock price may fluctuate in the future in response to any of the following factors, some of which are beyond our control:

Our common stock is subject to the “penny stock” rules of the Securities and Exchange Commission, which may make it more difficult for stockholders to sell our common stock.

The Securities and Exchange Commission has adopted Rule 15g-9 which establishes the definition of a “penny stock,” for the purposes relevant to us, as any equity security that has a market price of less than $5.00 per share, subject to certain exceptions. For any transaction involving a penny stock, unless exempt, the rules require that a broker or dealer approve a person’s account for transactions in penny stocks, and the broker or dealer receive from the investor a written agreement to the transaction, setting forth the identity and quantity of the penny stock to be purchased.

In order to approve a person’s account for transactions in penny stocks, the broker or dealer must obtain financial information and investment experience objectives of the person and make a reasonable determination that the transactions in penny stocks are suitable for that person and the person has sufficient knowledge and experience in financial matters to be capable of evaluating the risks of transactions in penny stocks.

The broker or dealer must also deliver, prior to any transaction in a penny stock, a disclosure schedule prescribed by the SEC relating to the penny stock market, which, in highlight form sets forth the basis on which the broker or dealer made the suitability determination, and that the broker or dealer received a signed, written agreement from the investor prior to the transaction.

Generally, brokers may be less willing to execute transactions in securities subject to the “penny stock” rules. This may make it more difficult for investors to dispose of the Company’s common stock if and when such shares are eligible for sale and may cause a decline in the market value of its stock.

27

Disclosure also has to be made about the risks of investing in penny stocks in both public offerings and in secondary trading and about the commissions payable to both the broker-dealer and the registered representative, current quotations for the securities and the rights and remedies available to an investor in cases of fraud in penny stock transactions. Finally, monthly statements have to be sent disclosing recent price information for the penny stock held in the account and information on the limited market in penny stock.

You may experience dilution of your ownership interest due to future issuance of our securities.

We are in a capital-intensive business and we may not have sufficient funds to finance the growth of our business or to support our projected capital expenditures. As a result, we may require additional funds from future equity or debt financings, including potential sales of preferred shares or convertible debt, to complete the development of new projects and pay the general and administrative costs of our business. We may in the future issue our previously authorized and unissued securities, resulting in the dilution of the ownership interests of holders of our common stock. We are currently authorized to issue 500,000,000 shares of common stock and 10,000,000 shares of preferred stock. We may also issue additional shares of common stock or other securities that are convertible into or exercisable for common stock in future public offerings or private placements for capital raising purposes or for other business purposes. The future issuance of a substantial number of common stock into the public market, or the perception that such issuance could occur, could adversely affect the prevailing market price of our common shares. A decline in the price of our common stock could make it more difficult to raise funds through future offerings of our common stock or securities convertible into common stock.

Our Board of Directors may issue and fix the terms of shares of our Preferred Stock without stockholder approval, which could adversely affect the voting power of holders of our Common Stock or any change in control of our Company.

Our Articles of Incorporation authorize the issuance of up to 10,000,000 shares of "blank check" preferred stock, $0.001 par value per share, with such designation rights and preferences as may be determined from time to time by the Board of Directors. Our Board of Directors is empowered, without shareholder approval, to issue shares of preferred stock with dividend, liquidation, conversion, voting or other rights which could adversely affect the voting power or other rights of the holders of our Common Stock. In the event of such issuances, the preferred stock could be used, under certain circumstances, as a method of discouraging, delaying or preventing a change in control of our company. 

We do not expect to pay dividends and investors should not buy our Common Stock expecting to receive dividends.

We do not anticipate that we will declare or pay any dividends in the foreseeable future. Consequently, you will only realize an economic gain on your investment in our common stock if the price appreciates. You should not purchase our common stock expecting to receive cash dividends. Since we do not pay dividends, and if we are not successful in establishing an orderly trading market for our shares, then you may not have any manner to liquidate or receive any payment on your investment. Therefore, our failure to pay dividends may cause you to not see any return on your investment even if we are successful in our business operations. In addition, because we do not pay dividends we may have trouble raising additional funds which could affect our ability to expand our business operations.

Our operating results are likely to fluctuate from period to period.

We anticipate that there may be fluctuations in our future operating results. Potential causes of future fluctuations in our operating results may include:

Our business, financial condition and results of operations could be materially adversely affected by various risks, including, but not limited to the principal risks noted below.

28

The requirements of the Sarbanes-Oxley Act of 2002 and other U.S. securities laws impose substantial costs and may drain our resources and distract our management.

We are subject to certain of the requirements of the Sarbanes-Oxley Act of 2002 in the U.S., as well as the reporting requirements under the Exchange Act. The Exchange Act requires, among other things, filing of annual reports on Form 10-K, quarterly reports on Form 10-Q and periodic reports on Form 8-K following the happening of certain material events, with respect to our business and financial condition. The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal controls over financial reporting.

Our internal control over financial reporting is a process designed under the supervision of our Chief Executive Officer, Chief Financial Officer and Chief Accounting Officer to provide reasonable assurance regarding the reliability of financial reporting and the preparation of our consolidated financial statements for external purposes in accordance with generally accepted accounting principles, or GAAP. Internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that receipts and expenditures are being made only in accordance with authorizations of our management and directors; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements.

We are subject to the Florida anti-takeover provisions, which may prevent you from exercising a vote on business combinations, mergers or otherwise.

As a Florida corporation, we are subject to certain anti-takeover provisions that apply to public corporations under Florida law. Pursuant to Section 607.0901 of the Florida Business Corporation Act, or the Florida Act, a publicly held Florida corporation may not engage in a broad range of business combinations or other extraordinary corporate transactions with an interested shareholder without the approval of the holders of two-thirds of the voting shares of the corporation (excluding shares held by the interested shareholder), unless the:

An interested shareholder is defined as a person who together with affiliates and associates beneficially owns more than 10% of a corporation’s outstanding voting shares. We have not made an election in our amended Articles of Incorporation to opt out of Section 607.0901.

In addition, we are subject to Section 607.0902 of the Florida Act which prohibits the voting of shares in a publicly held Florida corporation that are acquired in a control share acquisition unless (i) our board of directors approved such acquisition prior to its consummation or (ii) after such acquisition, in lieu of prior approval by our board of directors, the holders of a majority of the corporation’s voting shares, exclusive of shares owned by officers of the corporation, employee directors or the acquiring party, approve the granting of voting rights as to the shares acquired in the control share acquisition. A control share acquisition is defined as an acquisition that immediately thereafter entitles the acquiring party to 20% or more of the total voting power in an election of directors.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus contains forward-looking statements. Forward-looking statements give our current expectations or forecasts of future events. You can identify these statements by the fact that they do not relate strictly to historical or current facts. Forward-looking statements involve risks and uncertainties and include statements regarding, among other things, our projected revenue growth and profitability, our growth strategies and opportunity, anticipated trends in our market and our anticipated needs for working capital. They are generally identifiable by use of the words “may,” “will,” “should,” “anticipate,” “estimate,” “plans,” “potential,” “projects,” “continuing,” “ongoing,” “expects,” “management believes,” “we believe,” “we intend” or the negative of these words or other variations on these words or comparable terminology. These statements may be found under the sections entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Business,” as well as in this prospectus generally. In particular, these include statements relating to future actions, prospective products, market acceptance, future performance or results of current and anticipated products, sales efforts, expenses, and the outcome of contingencies such as legal proceedings and financial results.

Examples of forward-looking statements in this prospectus include, but are not limited to, our expectations regarding our business strategy, business prospects, operating results, operating expenses, working capital, liquidity and capital expenditure requirements. Important assumptions relating to the forward-looking statements include, among others, assumptions regarding demand for our products, the cost, terms and availability of components, pricing levels, the timing and cost of capital expenditures, competitive conditions and general economic conditions. These statements are based on our management’s expectations, beliefs and assumptions concerning future events affecting us, which in turn are based on currently available information. These assumptions could prove inaccurate. Although we believe that the estimates and projections reflected in the forward-looking statements are reasonable, our expectations may prove to be incorrect.

Important factors that could cause actual results to differ materially from the results and events anticipated or implied by such forward-looking statements include, but are not limited to:

We operate in a very competitive and rapidly changing environment. New risks emerge from time to time. It is not possible for us to predict all of those risks, nor can we assess the impact of all of those risks on our business or the extent to which any factor may cause actual results to differ materially from those contained in any forward-looking statement. The forward-looking statements in this prospectus are based on assumptions management believes are reasonable. However, due to the uncertainties associated with forward-looking statements, you should not place undue reliance on any forward-looking statements. Further, forward-looking statements speak only as of the date they are made, and unless required by law, we expressly disclaim any obligation or undertaking to publicly update any of them in light of new information, future events, or otherwise.

We have agreed to bear the expenses relating to the registration of the common stock for the Selling Stockholders.

31

DETERMINATION OF OFFERING PRICE

The selling stockholder will offer common stock at the prevailing market prices or privately negotiated prices.  The offering price of our common stock does not necessarily bear any relationship to our book value, assets, past operating results, financial condition or any other established criteria of value.  Our common stock may not trade at the market prices in excess of the offering prices for common stock in any public market will be determined in the marketplace and may be influenced by many factors, including the depth and liquidity. You should not assume or expect that our shares of common stock will trade at or above the exercise prices or the educed exercise price of the Warrants in any given time period.

DILUTION

Not applicable. The shares registered under the registration statement of which this prospectus forms a part are not being offered for purchase. The shares are being registered on behalf of the selling stockholders.

32

SELLING SECURITY HOLDERS

The common stock being offered by the Selling Stockholders are those previously issued to the Selling Stockholders, and those issuable to the Selling Stockholders, upon exercise of the warrants and conversion of the Series B Preferred Stock. We are registering the shares of common stock in order to permit the Selling Stockholders to offer the shares for resale from time to time. Except for the ownership of the shares of Series B Preferred Stock, common stock and the warrants, the Selling Stockholders have not had any material relationship with us within the past three years.

The table below lists the Selling Stockholders and other information regarding the beneficial ownership of the shares of common stock by each of the Selling Stockholders. The second column lists the number of shares of common stock beneficially owned by each Selling Stockholder, based on its ownership of the shares of preferred stock, common stock and warrants, as of the date hereof, assuming conversion of the Series B Preferred Stock and exercise of the warrants held by the Selling Stockholders on such date, without regard to any limitations on conversions or exercises. The third column lists the shares of common stock being offered by this prospectus by the Selling Stockholders.

In accordance with the terms of a registration rights agreement with the Selling Stockholders, this prospectus generally covers the resale of the sum of (i) the number of shares of common stock issued to the Selling Stockholders in the Private Offering (ii) the maximum number of shares of common stock issuable upon conversion of the related preferred stock, determined as if the outstanding shares of preferred stock were converted in full as of the trading day immediately preceding the date this registration statement was initially filed with the SEC, and (iii) the maximum number of shares of common stock issuable upon exercise of the related warrants, determined as if the outstanding warrants were exercised in full as of the trading day immediately preceding the date this registration statement was initially filed with the SEC, each as of the trading day immediately preceding the applicable date of determination and all subject to adjustment as provided in the registration right agreement, without regard to any limitations on the exercise of the warrants or the conversion of the preferred stock. The fourth column assumes the sale of all of the shares offered by the Selling Stockholders pursuant to this prospectus.

Under the terms of the warrants and the Series B Preferred Certificate of Designation, a Selling Stockholder may not exercise the warrants or convert the Series B Preferred Stock to the extent such exercise or conversion would cause such Selling Stockholder, together with its affiliates and attribution parties, to beneficially own a number of shares of common stock which would exceed 9.99% of our then outstanding common stock following such exercise or conversion, excluding for purposes of such determination shares of common stock issuable upon exercise of the warrants which have not been exercised and shares of common stock issuable upon conversion of the preferred stock which has not been converted. The number of shares in the second column does not reflect this limitation. The Selling Stockholders may sell all, some or none of their shares in this offering. See “Plan of Distribution.”

PLAN OF DISTRIBUTION

Each Selling Stockholder of the securities and any of their pledgees, assignees and successors-in-interest may, from time to time, sell any or all of their securities covered hereby on the principal Trading Market or any other stock exchange, market or trading facility on which the securities are traded or in private transactions. These sales may be at fixed or negotiated prices. A Selling Stockholder may use any one or more of the following methods when selling securities:

The Selling Stockholders may also sell securities under Rule 144 or any other exemption from registration under the Securities Act of 1933, as amended (the “Securities Act”), if available, rather than under this prospectus.

Broker-dealers engaged by the Selling Stockholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the Selling Stockholders (or, if any broker-dealer acts as agent for the purchaser of securities, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this prospectus, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with FINRA Rule 2440; and in the case of a principal transaction a markup or markdown in compliance with FINRA IM- 2440.

In connection with the sale of the securities or interests therein, the Selling Stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the securities in the course of hedging the positions they assume. The Selling Stockholders may also sell securities short and deliver these securities to close out their short positions, or loan or pledge the securities to broker-dealers that in turn may sell these securities. The Selling Stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or create one or more derivative securities which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The Selling Stockholders and any broker-dealers or agents that are involved in selling the securities may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the securities purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. Each Selling Stockholder has informed the Company that it does not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the securities.

The Company is required to pay certain fees and expenses incurred by the Company incident to the registration of the securities. The Company has agreed to indemnify the Selling Stockholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.

We agreed to keep this prospectus effective until the earlier of (i) the date on which the securities may be resold by the Selling Stockholders without registration and without regard to any volume or manner-of-sale limitations by reason of Rule 144, without the requirement for the Company to be in compliance with the current public information under Rule 144 under the Securities Act or any other rule of similar effect or (ii) all of the securities have been sold pursuant to this prospectus or Rule 144 under the Securities Act or any other rule of similar effect. The resale securities will be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the resale securities covered hereby may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

37

Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the resale securities may not simultaneously engage in market making activities with respect to the common stock for the applicable restricted period, as defined in Regulation M, prior to the commencement of the distribution. In addition, the Selling Stockholders will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of the common stock by the Selling Stockholders or any other person. We will make copies of this prospectus available to the Selling Stockholders and have informed them of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act).

MANAGEMENT’S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS

This Registration Statement on Form S-1 and other reports filed by the Company from time to time with the SEC (collectively, the “Filings”) contain or may contain forward-looking statements and information that are based upon beliefs of, and information currently available to, the Company’s management as well as estimates and assumptions made by Company’s management. Readers are cautioned not to place undue reliance on these forward-looking statements, which are only predictions and speak only as of the date hereof. When used in the Filings, the words “anticipate,” “believe,” “estimate,” “expect,” “future,” “intend,” “plan,” or the negative of these terms and similar expressions as they relate to the Company or the Company’s management identify forward-looking statements. Such statements reflect the current view of the Company with respect to future events and are subject to risks, uncertainties, assumptions, and other factors, including the risks relating to the Company’s business, industry, and the Company’s operations and results of operations. Should one or more of these risks or uncertainties materialize, or should the underlying assumptions prove incorrect, actual results may differ significantly from those anticipated, believed, estimated, expected, intended, or planned.

Although the Company believes that the expectations reflected in the forward-looking statements are reasonable, the Company cannot guarantee future results, levels of activity, performance, or achievements. Except as required by applicable law, including the securities laws of the United States, the Company does not intend to update any of the forward-looking statements to conform these statements to actual results.

Our financial statements are prepared in accordance with accounting principles generally accepted in the United States (“GAAP”). These accounting principles require us to make certain estimates, judgments and assumptions. We believe that the estimates, judgments and assumptions upon which we rely are reasonable based upon information available to us at the time that these estimates, judgments and assumptions are made. These estimates, judgments and assumptions can affect the reported amounts of assets and liabilities as of the date of the financial statements as well as the reported amounts of revenues and expenses during the periods presented. Our financial statements would be affected to the extent there are material differences between these estimates and actual results. In many cases, the accounting treatment of a particular transaction is specifically dictated by GAAP and does not require management’s judgment in its application. There are also areas in which management’s judgment in selecting any available alternative would not produce a materially different result. The following discussion should be read in conjunction with our financial statements and notes thereto appearing elsewhere in this Registration Statement on Form S-1.

Our Company

We intend for this discussion to provide information that will assist in understanding our financial statements, the changes in certain key items in those financial statements, and the primary factors that accounted for those changes, as well as how certain accounting principles affect our financial statements.

Our Company

Duos Technologies Group, Inc. was incorporated in Florida on May 31, 1994 (the “Company”) under the original name of Information Systems Associates, Inc. (“ISA”). Initially, our business operations consisted of consulting services for asset management of large corporate data centers and the development and licensing of information technology (“IT”) asset management software. In late 2014, ISA entered negotiations with Duos Technologies, Inc. (“duostech”), for the purposes of executing a reverse triangular merger. This transaction was completed on April 1, 2015, whereby duostech became a wholly owned subsidiary of the Company.  duostech was incorporated under the laws of Florida on November 30, 1990 for design, development and deployment of proprietary technology applications and turn-key engineered systems. The Company, based in Jacksonville, Florida, employs approximately 50 people and is a technology and software applications company with a strong portfolio of intellectual property. The Company’s core competencies, including advanced intelligent technologies, are delivered through its proprietary integrated enterprise command and control platform, centraco®.

Plan of Operation

The Company, through its operating subsidiary duostech, is primarily engaged in the design and deployment of advanced, artificial intelligence driven intelligent technologies systems. The Company converges traditional security measures with information technologies to create “actionable intelligence.”

The Company’s growth strategy includes expansion of its technology base through organic development efforts, strategic partnerships, and through strategic acquisitions. The Company provides its broad range of technology solutions with an emphasis on mission critical security, inspection and operations within the rail transportation, commercial, petrochemical, government, and banking sectors. The Company also offers professional and consulting services for large data centers.

Specifically, based upon the current and anticipated business growth, the Company is investing in resources to focus on execution within its target markets, including but not limited to rail, distribution centers and security. We continue to evaluate key requirements within those markets and add development resources to allow us to compete for additional projects to drive additional revenue growth.

Further, the Company is broadening its offerings in the IT asset management (“ITAM”) space for large data centers. During the quarter ended June 30, 2018, the Company announced its new dcVue software platform which is the basis for expanded offerings into this market area. The dcVue offering is a new software platform that replaces the Company’s On-Site Physical Inventory (OSPI) system that was commercially marketed from 2010 until 2015. OSPI was used by Duos’ ITAM auditing teams until early this year and has now been replaced by dcVue. dcVue is based upon the Company’s OSPI patent which was awarded in 2010. The Company will be making dcVue available for license to our customers later this year as a licensed software product. We intend to further develop our ITAM offerings for large data centers with the objective of offering existing Company technologies for data and video analytics. The Company implemented a new plan to expand and focus its sales efforts through the addition of strategic partners.

Prospects and Outlook

Over the past several years, we have made substantial investments in product research and development and achieved significant milestones in the development of our technology and turnkey solutions. We have made significant progress in penetrating the market with our proprietary technology solutions, specifically in the rail industry which is currently undergoing a major shift in maintenance strategies. We believe that this shift will be a significant motivating factor for the industry’s use of our technologies.

Our business success in the immediate future will largely depend on the increased penetration into our target markets for our proprietary intelligent analytical technology solutions.

Notwithstanding the above, no assurance can be provided that our product offerings will generate the market acceptance and orders that we contemplate.

Results of Operations

The following discussion should be read in conjunction with the consolidated financial statements included in this report.

For the year ended December 31, 2018 compared to December 31, 2017

The following table sets forth a modified version of our Consolidated Statements of Operations that is used in the following discussions of our results of operations:

Revenues

The significant increase in overall revenues is driven by the current strength of the projects portion of our business currently being undertaken. The Company’s stable capital structure enables us to more aggressively pursue large projects requiring the ability to deploy major resources. The significant increase in project revenues was also accompanied by an increase in maintenance and technical support.  This revenue source has been in transition for the past year as older legacy systems are replaced by the next generation of technology systems which are currently being installed. There is typically a lag of approximately 6 months installation of a new system until the recurring revenue is recognized. The Company continues to replace the declining revenues from one customer with new, long term recurring revenue from new customers which will be coming on-line in the next several months. The maintenance and technical support revenues are driven by successful completion on projects and represent services and support for those installations. The expectation is that revenues from this area will be flat for the first half of 2019 and then begin to grow based on the success of multiple installations in 2018.

The ITAM division experienced a significant reduction in revenues for 2018. This was the result of the conclusion of a large project late in 2017 and delays in starting a new project that was anticipated to begin earlier in 2018. The new project is now expected to begin in the second quarter of 2019. The ITAM division also released a new version of its software which is anticipated to broaden market acceptance of its offerings and we anticipate a positive impact on revenues anticipated in 2019.

41

Cost of Revenues

Cost of revenues on projects increased at a slower rate than the increase in revenues. The overall gross margin was positively impacted during the period compared to the equivalent period in 2017 due to tighter cost controls on production of systems and the efficiencies gained through the implementation of projects at the Operations and Engineering Center prior to customer deployment.  Cost of Revenues decreased by 11% on maintenance and technical support which is a positive trend against an increase in revenues and we expect this trend to continue as economies of scale begin to have a positive impact.  The Company also completed certain field work at the request of two major clients which increased revenue but at a margin that is less than in the normal course of business.  The effect of this is anticipated to be minimal going forward.

Gross Profit

Gross Profit was $5,204,223 or 43% of revenues compared to $1,590,036 or 41% of revenues for the twelve months ended December 31, 2018 and 2017, respectively. The overall increase in gross profit of 227% was mainly the result of the increase in project revenues and the positive effect of significant revenue increases from new projects. It should be noted that the accounting treatment was changed to the ASC 606 reporting standard and that the results compared with the previous year are not strictly comparable. As previously discussed, the implementation of ASC 606 covering revenue from contracts with customers, has a temporary impact on overall gross margin as certain costs are recognized ahead of revenues. Also, during the year, certain project revenue related to the management of construction requested by two customers were treated as a pass through and have between a 10% and a 25% gross margin. This has a negative overall effect on the typical project gross margin for an aggregate of our revenue sources of at least 50%. Despite these factors, the Company recorded an overall increase in Gross Margin for the year compared to the prior year which is a positive trend. Management anticipates the overall gross margins for the business to continue to improve in the coming year excluding the impact of “one-off” lower margin revenues related to field construction work requested by the customer and not in the ordinary course of business.

Operating Expenses

42

Operating expenses were higher by 35% for the year reflecting the increase in resources related to the significant increase in revenues for the period. Selling and marketing expenses and research and development both increased with the Company’s investment in resources to grow the business. The Company also began investing in its resources for the development of the new truevue360™ AI platform.  The 39% increase in salaries, wages and contract labor is due to a planned increase in the number of employees and additional contract expenses related to an overall significant increase in revenues.  This rate of increase is expected to slow in 2019. Professional fees were 38% lower due to a reduction in expenses related to legal fees and prudent management of expenses by management. Other G&A costs increased but were in line with the additional staff expenses and the growth of the Company. It is anticipated that overall operating expenses will grow at a slower rate than the revenue increases.

Loss From Operations

The losses from operations for the years ended, December 31, 2018 and 2017 were $1,569,904 and $3,443,493, respectively. This is a 54% reduction in loss as the Company moves toward breakeven and profitability.

Interest Expense

Interest expense for the years ended December 31, 2018 and 2017 were $17,180 and $4,519,035 respectively. The significant decrease in interest expense was primarily due to the Company’s non-cash debt expenses related to certain financing actions prior to completing the capital raise at the end of November 2017. In addition to being non-cash, the expenses were driven by interest expense related to certain warrants which required accounting as derivatives. Some of these extraordinary costs were offset by an overall non-cash gain recorded due to the valuations recorded in those derivative instruments. The affected warrants were cancelled and retired at the end of 2017 and will have no impact on the Company’s financial results going forward.

Other Income

Other income for the years ending December 31, 2018 and 2017 was $6,197 and $1,719 respectively.

Net Loss

The net loss for the years ended December 31, 2018 and 2017 was $1,580,887 and $5,152,477 respectively. The $3,571,590 decrease in net loss is primarily attributable to the increase in revenue and less than proportionate increase cost of revenue in 2018. Net loss applicable to Common Stock was $1,580,887 in 2018 versus $5,170,237 in 2017, a decrease of $3,589,350. Most of the difference between Operating Losses and Net Losses were non-cash in nature. Additionally, the loss in 2017 included a charge for Series A Preferred Stock Dividends of $17,760. Net loss per common share was $0.08 and $1.43 for the years ended December 31, 2018 and 2017, respectively.

Liquidity and Capital Resources

As of December 31, 2018, the Company has a cash balance of $1,209,301.

Cash Flows

The following table sets forth the major components of our statements of cash flows data for the periods presented:

Net cash used in operating activities for the years ended December 31, 2018 and 2017 were $345,287 and $3,562,306 respectively. The decrease in net cash used in operations for the year ended December 31, 2018 was almost exclusively due to a more than $2 million increase in contract liabilities.

43

Net cash used in investing activities for the years ended December 31, 2018 and 2017 were $285,678 and $41,709, respectively representing an increase in investments in software development and lab equipment during 2018.

Net cash used in financing activities for the year ended December 31, 2018 was $101,552 and cash flows provided in the year ended December 31, 2017 was $5,371,457. Cash flows used in financing activities during 2018 were primarily attributable to repayments of existing notes and short-term credit facilities. Cash flows provided by financing activities during 2017 were primarily attributable to proceeds from the issuance of common stock, offset by repayments of existing notes and short-term credit facilities.

Previously, we have funded our operations primarily through the sale of our equity (or equity linked) and debt securities. During 2018, we have funded our operations through revenues generated and cash received from ongoing project execution and associated maintenance revenues. As of April 5, 2019, we had cash on hand of approximately $1,451,000. We have approximately $135,000 in monthly lease and other mandatory payments, not including payroll and ordinary expenses which are due monthly.

On a long-term basis, our liquidity is dependent on continuation and expansion of operations and receipt of revenues. Our current capital and revenues are sufficient to fund such expansion although we are dependent on timely payments by our customers for projects and work in process.

Demand for the products and services will be dependent on, among other things, market acceptance of our products and services, the technology market in general, and general economic conditions, which are cyclical in nature. In as much as a major portion of our activities is the receipt of revenues from the sales of our products and services, our business operations may be adversely affected by our competitors and prolonged recession periods although these are not considered to be a factor at present.

Going Concern and Liquidity

Under Accounting Standards Update, or ASU, 2014-15, Presentation of Financial Statements—Going Concern (Subtopic 205-40) (“ASC 205-40”), the Company has the responsibility to evaluate whether conditions and/or events raise substantial doubt about its ability to meet its future financial obligations as they become due within one year after the date that the financial statements are issued. As required by ASC 205-40, this evaluation shall initially not take into consideration the potential mitigating effects of plans that have not been fully implemented as of the date the financial statements are issued. Management has assessed the Company’s ability to continue as a going concern in accordance with the requirement of ASC 205-40.

As reflected in the accompanying consolidated financial statements, the Company had a negative working capital of $469,081 and an accumulated deficit of $30,269,833 at December 31, 2018. During the same period in 2017, the Company had a positive working capital of $550,332 and an accumulated deficit of $28,688,946.

The Company’s consolidated financial statements are prepared assuming the Company can continue as a going concern, which contemplates continuity of operations through realization of assets, and the settling of liabilities in the normal course of business. While our auditor has expressed substantial doubt regarding our ability to continue as a going concern, management’s assessment is that with the current cash on hand, business backlog and expected orders, and anticipated cash raised from warrant exercises, that the Company will continue as  Going Concern for at least 12 months from the date of this report. Our plan regarding these matters is to closely monitor our progress against our documented pro-forma financial plan, manage expenses accordingly to allow us the ability to cover our current cash flow requirements and meet our obligations as they become due. If this is insufficient due to unforeseen circumstances, there can be no assurances that financing will be available or if available, that such financing will be available under favorable terms.

Management believes that the Company has reached the point where anticipated profitable operations from current backlog in the final quarter of the year will allow continuation as a going concern for a period of at least twelve months from the date these financial statements have been issued. The ability to recognize revenue and ultimately cash receipts is contingent upon, but not limited to, acceptable performance of the delivered services. If the Company is unable to complete on some of its revenue producing opportunities in the near term, the ability to continue as a going concern based on management’s assessment may be impacted.

Off Balance Sheet Arrangements

We have no-off balance sheet contractual arrangements, as that term is defined in Item 303(a)(4) of Regulation S-K.

Critical Accounting Policies and Estimates

The discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with generally accepted accounting principles in the United States. The preparation of these financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates. The most significant estimates in the accompanying consolidated financial statements include the allowance on accounts receivable, valuation of deferred tax assets, valuation of intangible and other long-lived assets, estimates of net contract revenues and the total estimated costs to determine progress toward contract completion, valuation of derivatives, valuation of warrants issued with debt, valuation of beneficial conversion features in convertible debt and valuation of stock-based awards. We base our estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates.

We have identified the accounting policies below as critical to our business operations and the understanding of our results of operations.

Revenue Recognition and Contract Accounting

The Company generates revenue from three sources: (1) Project Revenue; (2) Maintenance and Technical Support and (3) IT Asset Management (consulting and auditing).

Project Revenue

The Company constructs intelligent technology systems consisting of materials and labor under customer contracts. Revenues and related costs on project revenue are recognized based on ASC 606-10-25-27, where control of a good or service transfers over time if the entity’s performance does not create an asset with an alternative use to the entity and the entity has an enforceable right to payment for performance completed to date including a profit margin or reasonable return on capital. Control is deemed to pass to the customer instantaneously as the goods are manufactured and revenue is recognized accordingly.

In addition, the Company has adopted ASC 606-10-55-21 such that if the cost incurred is not proportionate to the progress in satisfying the performance obligation, we adjust the input method to recognize revenue only to the extent of the cost incurred. Therefore, the Company will recognize revenue at an equal amount to the cost of the goods to satisfy the performance obligation. To accurately reflect revenue recognition based on the input method, the Company has adopted the implementation guidance as set out in ASC 606-10-55-187 through 192.

Under this method, contract revenues are recognized over the performance period of the contract in direct proportion to the costs incurred. Costs include direct material, direct labor, subcontract labor and other allocable indirect costs. All un-allocable indirect costs and corporate general and administrative costs are also charged to the periods as incurred. Any recognized revenues that have not been billed to a customer are recorded as an asset in “contract assets”. Any billings of customers more than recognized revenues are recorded as a liability in “contract liabilities”. However, in the event a loss on a contract is foreseen, the Company will recognize the loss when such loss is determined.

Maintenance and Technical Support

Maintenance and technical support services are provided on both an as-needed and extended-term basis and may include providing both parts and labor.  Maintenance and technical support provided outside of a maintenance contract are on an as-requested basis, and revenue is recognized as the services are provided.  Revenue for maintenance and technical support provided on an extended-term basis is recognized ratably over the term of the contract.

For sales arrangements that do not involve multiple elements such as professional services, which are of short-term duration, revenues are recognized when services are completed.

45

IT Asset Management Services

The Company recognizes revenue from its IT asset management business in accordance with the Securities and Exchange Commission (the “SEC”) Staff Accounting Bulletin No. 104, "Revenue Recognition" and Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 985-605-25 which addresses Revenue Recognition for the software industry. The general criteria for revenue recognition under ASC 985-605 for our Company, which sells software licenses, which do not require any significant modification or customization, is that revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred, the fee is fixed or determinable and collectability is probable.

The Company’s IT asset management business generates revenues from three sources: (1) Professional Services (consulting and auditing); (2) Software licensing with optional hardware sales and (3) Customer Service (training and maintenance support).

For sales arrangements that do not involve multiple elements: 

(1)

Revenues for professional services, which are of short-term duration, are recognized when services are completed;

(2)

For all periods reflected in this report, software license sales have been one-time sales of a perpetual license to use our software product and the customer also has the option to purchase third party manufactured handheld devices from us if they purchase our software license. Accordingly, the revenue is recognized upon delivery of the software and delivery of the hardware, as applicable, to the customer;

(3)

Training sales are one-time upfront short-term training sessions and are recognized after the service has been performed; and

(4)

Maintenance/support is an optional product sold to our software license customers under one-year contracts. Accordingly, maintenance payments received upfront are deferred and recognized over the contract term.

Multiple Elements

Arrangements with customers may involve multiple elements including project revenue and maintenance services in our Intelligent Technology Systems business. Maintenance will occur after the project is completed and may be provided on an extended-term basis or on an as-needed basis. In our IT Asset Management business, multiple elements may include any of the above four sources. Training and maintenance on software products may occur after the software product sale while other services may occur before or after the software product sale and may not relate to the software product. Revenue recognition for multiple element arrangement is as follows:

Each element is accounted for separately when each element has value to the customer on a standalone basis and there is Company specific objective evidence of selling price of each deliverable. For revenue arrangements with multiple deliverables, the Company allocates the total customer arrangement to the separate units of accounting based on their relative selling prices as determined by the price of the items when sold separately. Once the selling price is allocated, the revenue for each element is recognized using the applicable criteria under GAAP as discussed above for elements sold in non-multiple element arrangements. A delivered item or items that do not qualify as a separate unit of accounting within the arrangement are combined with the other applicable undelivered items within the arrangement. The allocation of arrangement consideration and the recognition of revenue is then determined for those combined deliverables as a single unit of accounting. The Company sells its various services and software and hardware products at established prices on a standalone basis which provides Company specific objective evidence of selling price for purposes of multiple element relative selling price allocation. The Company only sells maintenance services or spare parts based on its established rates after it has completed a system integration project for a customer. The customer is not required to purchase maintenance services. All elements in multiple element arrangements with Company customers qualify as separate units of account for revenue recognition purposes.

Accounts Receivable

Accounts receivable are stated at estimated net realizable value. Accounts receivable are comprised of balances due from customers net of estimated allowances for uncollectible accounts. In determining the collections on the account, historical trends are evaluated, and specific customer issues are reviewed to arrive at appropriate allowances. The Company reviews its accounts to estimate losses resulting from the inability of its customers to make required payments. Any required allowance is based on specific analysis of past due accounts and also considers historical trends of write-offs. Past due status is based on how recently payments have been received from customers.

46

Long-Lived Assets

The Company evaluates the recoverability of its property, equipment, and other long-lived assets in accordance with FASB ASC 360-10-35-15 “Impairment or Disposal of Long-Lived Assets”, which requires recognition of impairment of long-lived assets in the event the net book value of such assets exceed the estimated future undiscounted cash flows attributable to such assets or the business to which such intangible assets relate. This guidance requires that long-lived assets and certain identifiable intangibles be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell.

BUSINESS

Our Corporate History

We were incorporated on May 31, 1994 in the State of Florida as Information Systems Associates, Inc. (the “Company”, “we”, “us”, “our”). Initially, our business operations consisted of consulting services for asset management of large corporate data centers and development and licensing of Information Technology (IT) asset management software. On April 1, 2015, we completed a reverse triangular merger, pursuant to an Agreement and Plan of Merger (the “Merger Agreement”) among Duos Technologies, Inc., a Florida corporation (“DTI”), the Company, and Duos Acquisition Corporation, a Florida corporation and wholly owned subsidiary of the Company (“Merger Sub”). Under the terms of the Merger Agreement, the Merger Sub merged with and into DTI, whereby DTI remained as the surviving corporation and a wholly-owned subsidiary of the Company (the “Merger”). On the same date, TrueVue 360, Inc., a Delaware corporation, became a wholly owned subsidiary of the Company. In connection with the Merger, on July 10, 2015, the Company effected a name change to Duos Technologies Group, Inc.

Overview

The Company, through its wholly owned subsidiary DTI, focuses on the design, development and turnkey delivery of proprietary “intelligent technologies” that enable our customers to derive measurable increases in return on investment for their business. Our technologies integrate with our customer’s existing business process and create actionable information to streamline mission critical operations. Our target market is the largest transportation, industrial and retail corporations representing over $100 billion in total available market. Our technologies have been verified by multiple government and private organizations including Johns Hopkins University Applied Physics Laboratory (JHU/APL), the Department of Homeland Security (DHS) and the Transportation Technology Center, Inc., a wholly owned subsidiary of the Association of American Railroads, and a transportation research and testing organization (TTCI). The Company has worked with these organizations over the past several years where we have supplied funded prototypes of our technologies to verify technology and operating parameters.

The Company provides a broad range of sophisticated intelligent technology solutions with an emphasis on security, inspection and operations for critical infrastructure within a variety of industries including transportation, retail, law enforcement, oil, gas and utilities sectors. In January 2019, the Company launched a dedicated Artificial Intelligence program truevue360™ through its subsidiary, TrueVue360, Inc., (“TrueVue360”) with the objective of focusing the Company’s advanced intelligent technologies in the areas of Artificial Intelligent, Deep Machine Learning and Advance Algorithms to further support our business growth.  Consequently, our business operations are now in three business units: intelligent technologies, AI/machine learning platforms and IT asset management.

Our proprietary applications include but are not limited to:

Intelligent Rail Inspection Portal (rip™)

§

A suite of sub-systems for the automated inspection of freight or transit railcars while in motion. The objective is to automatically detect anomalies such as open or missing hatches, open cargo doors, illegal riders hiding in cargo wells, and an expanding number of mechanical defects, all while the train is traveling through various strategic areas (i.e. border crossings or inspection areas). The anomalies are detected through a combination of visual inspections, utilizing the Company’s proprietary remote user interface which displays ultra-high definition images of a 360-degree view of each rail car, and by a growing number of the Company’s proprietary artificial intelligence (AI) based algorithms. The inspection portal is typically installed between two rail yards and the inspection takes place while the trains are at speed of up to 70 MPH.  A higher speed version is available but not deployed yet as the current market does not yet require the higher speed version. Detections are reported to the respective rail yards well ahead of the train arrival at the yard.

Vehicle Undercarriage Examiner (vue™)

§

A system that inspects the undercarriage of railcars (both freight and transit rail) traveling at speeds of up to 140 miles per hour. The original maximum speed of 70MPH has been superseded by further development work which was completed recently. The addition of algorithms for an increasing number of automated detection of anomalies is a continuing development, which once completed and successfully tested, may have a significant impact on our revenues. The next version upgrade is scheduled to be completed by the end of the second quarter of 2019.

48

Thermal Undercarriage Examiner

§

Under a development award from the TTCI (the technology evaluation arm of the American Association of Railroads (“AAR”)), the Company developed and deployed a prototype thermal undercarriage examiner during the latter part of 2018.  The system uses high-speed thermal imaging technology to inspect the thermal signature of undercarriage components, with the focus on locomotives. Thermal monitoring of component heat signatures while underway will provide indications of the overall operating health of the locomotive that are not possible to observe during static inspections. Initial system performance has been very encouraging, and the Company received several orders from various class-1 rail operators who will be evaluating the system on revenue tracks. The t-vue design is undergoing further design refinements and sensitivity adjustments and is expected to be deployed commercially by the end of the second quarter of 2019. This system is considered a breakthrough in detection technologies as it is capable of detecting anomalies of trains at speed which were not detectable with currently available technologies.

Multi-Layered Enterprise Command and Control Interface (centraco®)

§

Aggregator and central point for information consolidation, systems management and communications of our proprietary systems and third-party applications.

Tunnel and Bridge Security

§

A suite of intelligent technologies-based homeland security applications for the security of critical tunnels and bridges.

Virtual Security Shield

§

A suite of intelligent technologies-based homeland security applications for the security of critical areas and buffer zones. This application includes intrusion detection zone, Radio Frequency Identification (RFID) tracking and discriminating “Friend or Foe” modules (Friend or Foe refers to a Radio Frequency - based tagging system that validates individuals authorized to be in a specific area).

Facility Safety and Security

§

A suite of intelligent technologies-based homeland security applications for the “hardening” or safety and resilience of facilities against natural or man originated threats for the protection of critical facilities (energy, water, chemical facilities). The Company and most of its staff are CFATS (Chemical Facility Anti-Terrorism Standards) certified.

Remote Bridge Operation

§

Proprietary system for remote control of draw bridges.

Pantograph Inspection System

§

A system designed to inspect pantographs (structure connecting transit locomotives to high voltage power lines) for the detection of excessive depletion of carbon liners, which may cause power line ruptures.  The Company is in the process of upgrading these technologies to add 3-D capabilities and artificial intelligence-based automated detection capabilities.
