NLOS МОБИЛЬНЫЙ / V системы передачи

"YTMW"Mobile A/V transmission device includes mini-receiver and mini-transmitter. The mini-transmitter is high power output, with transmitting antenna, digital modulation and A/V digital compress functions. This device is designed with compact structure, light weight and portability. It have the function of transmit one way video & 2 ways audio signal(1 way data transmission is optional).It is the ability to collect and transmit high-quality image on the scene. It supports transmission range up to 50KM under intervisibility conditions so you can use it to built up a hight quality A/V communication system in solider-solier,solider - base,vehicle-vehicle, vehicle - ship platform. Product Features With the technology of Multiband and direct frequency conversion With the technology of multi-bandwidth COFDM Modulation Multi-mode video compress: MPGE4 /MPEG2 compatibility High Receiver Threshold-signal Level: Sensitivity -103dBm(10-6 BER @4MHz Channel Breadth) AES Encrypting function: To avoid unlawfully receiving Manual key control 14dB Power output: 110mW 2.2W(It is convenient to change power, and reduce radiation) Manual key control 8 channel choosing:It is convenient to change frequency and avoid interfere.) High video quality: no mosaic, the last picture will be saved well.
