IP explosion-proof intercom adopts TCP/IP technology, which transmits audio signals in the form of data packets in Lan and wide area network. It is a hands-free intercom system with pure digital transmission. It solves the problems existing in the traditional intercom system, such as limited transmission distance and easy interference. A set of intercom microphone is installed in the center of the IP explosion-proof horn data center. Install multiple intercom explosion-proof intercom terminals and explosion-proof horn loudspeaker at the explosion-proof point. Two-way communication between command center and explosion-proof intercom terminal. At the same time, the command center can send voice commands to explosion-proof horn speakers.
