2W Video Radio Transmitter For NLOS Scenario
Product Description:
HMMAT01-UP is a new kind of 1080P broadcasting radio COFDM equipment that is designed for long distance video transmission for news gathering, television outside broadcasts and studio applicaiton.
The product supports both HD and SD cameras with low delay and V mount , one side for camera mounted and other side for Li-battery powered, convenient to be carried and installed.
Meanwhile being adopted the latest leading COFDM technology with H.264 compression, this system can perform video transmission in high-speed motion and NLOS(non line of sight)condition.
Product Sell Point:
1. Two-way voice communication
2. 40ms latency
3. COFDM modulation and H.264/H.265 image compression
4. Strong diffraction in non line of sight city transmission
5. HDMI,SDI,CVBS video input are available
