Duos to Provide Additional Two Years of Maintenance and Support for Existing, Long-Term Customer

JACKSONVILLE, FL / ACCESSWIRE / May 29, 2019 / Duos Technologies Group, Inc. ("Duos" or the "Company" or "our") (OTCQB: DUOT), through its operating subsidiary Duos Technologies, Inc., a provider of intelligent security and analytical technology solutions, has received an award renewing its maintenance and support agreement with a long-time customer of its Rail Inspection Portal (rip^®) technology. The contract specifies that Duos will provide an additional two years of service, extending the initial eight years that the Company has already been supporting this customer. The scope of work covered in the agreement requires uninterrupted software service, tech support and maintenance for the customer's portals, which currently perform a vital role in various inspections occurring at the US/Mexico border.

"Our premium software and tech support services are key to maintaining the high quality and functionality of our rail inspection portal technologies," said Gianni Arcaini, Duos Chairman and CEO. "The challenges that U.S. Customs and Border Protection faces day-to-day require guaranteed performance quality, making it critical that our inspection portals operate as intended. With this extension of our services, our Class 1 customer continues to recognize the value of our border security applications and re-affirms confidence in our abilities to maintain and support our installations. Going forward, we are continuing to make investments in our own infrastructure to ensure that our growing installed base of portals for railcar inspections is well supported into the future."

Separately, Duos is advancing its other capabilities for the rail transportation business and is expected to release a number of new technologies throughout 2019. Services supporting existing and planned new products include 24/7 support, preventative maintenance, inspection services and machine learning algorithms.
