Wireless Video Transmitter
Cofdm Video Transmitter
XK-V103TDS transmitter is a micro HD wireless 4-channels Video transmission system(with two-way voice) for Fire fighting special robot.. Based on COFDM modulation, H. 264 compression and AES encryption, with multi-channel video transmission function, support up to four channels of image transmission simultaneously. It supports two-way data transmission, not only can transmit front-end information to the back-end (such as robot status, site environment information, etc.), but also can transmit back-end commands to the front-end, such as remote control of robots and transmitters. XK-V103TDS transmitter supports non line-of-sight transmission, with long distance, strong anti-interference ability, low transmission bandwidth and small transmission delay; it can be widely used in army, public security, armed police, fire protection, water conservancy, electric power, maritime, customs, radio and television industries, the collocation with UGV/USV/Vehicle is one of the most popular application at present.
