COFDM NLOS Mobile Audio and Video Transmitter and Receiver
Description:
ST-6000TBH COFDM NLOS Mobile A/V Transmission System 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 50km
