5W Long Range COFDM Transmitter , Waterproof Wireless Video Sender , Up To 80km
?
?
Introduction:
?
The Knapsack Digital Wireless Video Transmitter adopts the latest technologies of COFDM modulation and MPEG-2 image compression that enables good NLOS (Non line-of -sight) transmission with DVD quality video. The transmitter is compact size with power amplifier for longer-range transmission. This system has been widely used in many fields such as: Police Forces, First Responders, Security Services, Fire Services, Port Security, Homeland Security, Traffic Management, Police Technical Support Units, Special Forces, Military Command and Control Posts, Airport, Border Control, Major Incident Support.
