COFDM Non line-of -sight Security Wireless Video & Data Transmission 1080P HD

HD Long Range Wireless Transmitter Introduction:

KP-HD20 is a new arrival digital wireless video audio transmitter which adopts the latest technologies of COFDM modulation and MPEG-4 image compression that enables good NLOS (Non line-of -sight) transmission with DVD quality video. The transmitter is compact size with strong power amplifier for longer-range transmission. Good heat resistant with two cooling fans. Be safety with AES128/256bits.Can work well in fast-moving transmission.


  • COFDM modulation, Stable transmission
  • Several wavebands available: VHF/L/ S
  • MPEG-4/H.264 video compression, DVD video quality
  • Military aluminum housing ,Strong casing with built-in two cooling fans
  • Mobile and NLOS(Non line-of-sight) 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 like HDMI/HD-SDI, data port, Ehernet and etc..
