Backpack COFDM Video Transceiver System YS-1008A

Apply: Police Forces, First Responders, Security Services, Fire Services, Port Security, Homeland Security, Traffic Management

Yishi Backpack CFODM Video Transceiver Sys(named YS-1008A): Digital Wireless Video Transceiver System(one TX and one RX) 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

The transmission range is 5-10km in NLOS(non line-of-sight)condition and 30-60km in LOS(line-of-sight)condition

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.
