2W/5W backpack COFDM wireless mobile video transmitter and receiver http://www.0086cctv.com/2w-5w-backpack-cofdm-wireless-mobile-video-transmitter-and-receiver
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.
Features:
■COFDM modulation, Stable transmission
■MPEG-2 video compression, DVD video quality
■Lithium battery for power supply
■Mobile and NLOS(Non line-of-sight) transmission
■Great security by encryption of AES 128 bit/ALLTECH Basic Scrambling
■Low system latency
■Modular design, compact structure, small cubage
■Several wavebands available: VHF/L/ S
■Strong casing with built-in cooling plates, waterproof and shockproof
■In LOS (line-of-sight)environment, the transmission range is up to 80km
Product Application:
The Knapsack Digital Wireless Video Transmission system is the ideal solution for first responders or military personnel entering hazardous environments. The first responder can carry the equipment on the back to enter accident ground and then the transmitter send the camera’s digital, compressed signals to the commanding center.
