Outdoor Long Range COFDM Wireless HD Video Transmitter for Vehicle FOB Reference Price
DS-HDT20W 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 longer-range transmission. Good heat resistant with two cooling fans. Be safety with AES128 bits. It works well in fast-moving transmission.
1.Inset high-powered amplifier and cooling fans.
2. Stable transmission with omni-directional antenna.
3. COFDM modulation and H.264 video compression.
4. Adjustable working frequency, LCD board displays the parameters
5. Great security by encryption of AES 128 bit
6. Rack mountable design, can be installed in a car or helicopter.
7. Good transmission with high definition image and stereo audio.
8. Stable transmission in NLOS(non line-of-sight)and high speed mobile condition.
9. The transmission range is 50-100km in NLOS and more than 100km in LOS(line-of-sight)condition.
