(ShareCast News) - AIM-listed security and surveillance company Digital Barriers has secured a $2.2m contract to provide its EdgeVis Live advanced wireless surveillance technology to a flagship US Federal law enforcement agency.The revenue associated with the contract is expected to be fully recognised in this financial year and lead to further material awards this year and in subsequent years.The EdgeVis Live surveillance technology offers users secure distribution of real-time video from anywhere to anywhere. It features end-to-end security, real world resilience and network optimisation that can stream usable, live video using 60% less bandwidth than standard technologies.Chief executive officer Zak Doffman said: "The size and nature of this contract, which is expected to lead to significant follow-on awards is testament to the strong position we now have in the US following the acquisition of Brimtek earlier this year."Selling Digital Barriers' technology using Brimtek's strength and reach in the US was the central strategic rationale behind the deal. The adoption of EdgeVis Live by the world's most aspirational customers perfectly illustrates the significant technical lead it enjoys over its competition."
