Digital video has become an indispensable tool for remote surveillance applications; wireless technology has enabled video surveillance to be deployed across wide areas without the costs associated with physical connectivity. Municipalities, public safety organizations and transportation agencies rely heavily on real-time video monitoring for security, traffic management and emergency operations.
Video surveillance networks can span hundreds of square miles and use hundreds of networked video cameras. It is, thus, essential for the wireless network supporting these cameras — the backhaul network in particular — to have sufficient capacity and lowest latency to carry the aggregated camera traffic to the various video surveillance centers and monitoring agencies.
Capacity needs can add up fast, as high quality video cameras can each generate 0.5 - 3 Mbps of traffic, depending on image resolution, frame rate, video compression type, number of monitoring and recording hours, and whether cameras operate continuously or are event-driven. The backhaul capacity needed to transport traffic from 10 locations with 5 cameras each to a monitoring control center could be as much as 150 Mbps of unidirectional traffic.
The Exalt microwave radio portfolio, including the new ExtendAir line, features a wide range of models and capabilities designed to meet the backhaul requirements of video surveillance applications of every type:
