This is a new arrival digital wireless video audio transmitter which adopts the latest technologies of
COFDM modulation and H.264 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
long range transmission. Good heat resistant with two cooling fans. Be safety with AES128/256bits.
Can work well in fast-moving transmission.
With 15W~25W rf power, the video transmitter can easily DS-HDT20W achieve 15~20km long range wireless video in urban area, and with 1920*1080P high quality broadcast standard image.
