Vehicle mounted COFDM Video Transmitter with 20W Output Power Long Range Digital Transmitter

COFDM Digital Transmitter Feature:

  • COFDM modulation, Stable transmission
  • MPEG-4/H.264 video compression, DVD video quality
  • Strong casing with built-in two cooling fans
  • Mobile and NLOS transmission
  • Great security by encryption of AES 128 bits
  • Low system latency
  • Modular design, compact structure, OEM design
  • Can be customized to add additional features, such as HD/HD-SDI, data port, Ethernet and etc.


This is a new arrival digital wireless video audio transmitter which adopts the latest technologies of COFDM modulation and H.265 image compression that enables good NLOS (Non-line-of -sight) transmission with DVD quality video. The transmitter is compact in size with a strong power amplifier for longer-range transmission. Good heat resistant with three cooling fans. Be safe with AES128/256bits. Work well in fast-moving transmission and obstruction environment.
