Everyone knows that a wireless bridge is a device used to transmit signals, and is composed of a transmitting device and a receiving end. But the signal is a general term. It can contain many types of signals. Which signals can the wireless bridge transmit in the application? Let's take a look at it.
1, transmission of audio and video
A wireless bridge is a full-duplex device that not only transmits audio signals, but also enables two-way voice intercom. If the front-end network camera and the back-end network DVR have audio input and output ports, they can be directly transmitted through the wireless bridge without signal conversion. If the audio is transmitted separately, if it is not a network interface, it needs to be converted into a network interface, and then the front-end video signal is transmitted through the switch and then transmitted.
2, transfer data
In some special circumstances, to use wireless bridge to transmit data, the data interface must be converted into a network interface through hardware to transmit normally. The wireless bridge can realize two-way data transmission.
3, transmission network signal
In some places, we need to achieve wireless monitoring, but also need to achieve wireless coverage, then we do not need to separately increase the backbone transmission network signal equipment, we access the wireless monitoring video receiver through the switch, the front-end network signal Return it.
3, wireless bridge transmission switch
Generally, in power plants, reservoirs, pumping stations, etc., it is necessary to transmit the switch quantity of some equipment through the wireless bridge to remotely control the front-end equipment. At this time, we need to convert the switch quantity into a network signal and then pass the wireless network. Bridge to transmit.
5, wireless bridge transmission PTZ control signal
The pan/tilt in the network dome of the wireless monitoring system controls the direction of its rotation and movement in the remote by the control system. This PTZ control signal in the wireless monitoring system also needs to be transmitted through the wireless bridge, and reverse data transmission is also required. The use of a wireless bridge to transmit signals does not require separate transmission equipment to control, and the front-end signal can be connected to the wireless bridge to achieve remote pan/tilt control.
