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

Introduction

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, H. 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, etc.) 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, public security, armed police, fire protection, water conservancy, electric power, maritime, customs, radio and television industries, the collocation with Fire fighting special robot is one of the most popular application at present.
