Ground robot two-way bidirectional wireless data video audio transmitter receiver four channel SDI input 2W PA with receiver

مقدمه

This transmitter is a micro HD wireless 4-channels Video transmission system(with two-way voice) for Fire fighting special robots. Based on COFDM modulation, اچ. 264 compression and AES encryption, with a 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, و غیره) but also can transmit back-end commands to the front-end, such as remote control of robots and transmitters. This transmitter supports non-line-of-sight transmission, with long distance, strong anti-interference ability, low transmission bandwidth, and low latency transmission delay; it can be widely used in the army, امنیت عمومی, پلیس مسلح, fire protection, حفظ آب, قدرت الکتریکی, maritime, آداب و رسوم, radio and television industries, the collocation with Fire fighting special robot is one of the most popular application at present.
