150km UAV Video Link COFDM Digital HD AV Transmitter and Receiver H.265
Long range UAV video link Introduction:
DS-HDT20WG is a new arrival digital wireless video audio transmitter which adopts the latest technologies of COFDM modulation and H.265/H.264 image compression that enables good NLOS (Non line-of -sight) transmission with 1080P/I HD quality video.
The transmitter is with compact size and strong power amplifier for stable signal and long range transmission. Good heat resistant with three cooling fans. Be safety with AES128/256bits. Work well in fast-moving transmission and obstruction environment.
DS-HDT20WG supports RS232 signal and up to 150km wireless video link from drone/UAV to ground control station with high quality and stable image signal. It is also suitable for image transmission with the ground, and can be used in the fields of public security investigation, military operations, fire special robots, etc.
