20W Rugged COFDM HD Video Transmitter 10-15km NLOS Wireless Long Range AV Sender Encrypted
Video transmitter for mobile wireless communication HD video wireless unit is a new designed COFDM video FHD transmitter for gathering image, audio and data from front-end to command centre in emergency situation.
Designed in military-grade quality, it’s widely applied in tactical man-pack long distance wireless communication. With the features of latest COFDM technology, 20W high RF power, H.264 image compression, and full HD quality video definition, makes it enable to achieve long distance video and radio transmission even in the fast moving and harsh NLOS environment.
The HD COFDM wireless vidoe transmitter can also be designed for UAV, vehicle, boat point to point wireless long range communication.
Features:
* MPEG-4 /H.264 video compression, full HD video quality
* Military aluminum housing, black or green color option
* Mobile and NLOS (Non line-of-sight) transmission
* Strong security by AES user-defined encryption
* Low system latency
* Modular design, compact structure, OEM design
* Several wavebands available: VHF/UHF/L/ S
* Built-in very good heat radiation.
