Wireless bridges are used in wireless monitoring to implement communication between two or more networks. A wireless bridge is an ad hoc network that does not require the use of outside networks to transmit signals. Then everyone knows that the interface of the wireless bridge is RJ45, but in some special environments or places need to transmit audio, data, network signals, digital signals, PTZ control signals, etc., then the use of Levin technology wireless bridge to transmit other How can we achieve this signal?
1, wireless bridge to transmit audio wireless bridge is a full-duplex equipment, then we can not only use Shenzhen Lai-an technology wireless bridge to transmit audio signals, but also to achieve two-way voice intercom. If your front-end IP camera and back-end network DVR have audio input and output ports, they can be transmitted directly through the wireless bridge without the need for signal conversion. If the audio is transmitted separately, then look at what interface your audio device is. 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 after being centralized. This type of situation is generally most common in audio broadcast systems in parks.
2, wireless bridge to data transmission In some special circumstances, we have to use Shenzhen Lai-an technology wireless bridge to transmit data, then we must through the hardware to data interface into a network interface to normal transmission, wireless bridge can be achieved Bidirectional data transmission.
3. Using wireless bridges to transmit network signals In some venues, we need to implement wireless monitoring and also need to achieve wireless coverage. At this time, we do not need to separately increase the backbone transmission network signal equipment, we access through the switch Shenzhen Lian Technology wireless surveillance video receiver, the front-end network signal can be returned.
4, wireless bridge transmission switch is generally in power plants, reservoirs, pumping stations and other places need to pass wireless bridges to switch the amount of certain equipment, to remotely control the front-end equipment, then we need to switch the switch with hardware After the network signal, it is transmitted through the Shenzhen Leian Technology Wireless Bridge.
5, wireless bridge transmission PTZ control signal Wireless monitoring system in the network ball machine in the PTZ is through the control system in the remote can control its rotation and movement direction. PTZ rotation speed is an important indicator of the level of PTZ. The horizontal and vertical directions of the pan tilt are driven by two different motors. Therefore, the pan/tilt rotation speed is also divided into horizontal rotation speed and vertical rotation speed. Due to the load, the torque of the vertical motor when starting and running is greater than the torque in the horizontal direction. In addition to the actual monitoring, the requirement for the horizontal rotation speed is higher than the vertical rotation speed. Therefore, in general, the vertical speed of the PTZ is lower than Horizontal speed.
How to control the pan/tilt to rotate horizontally or vertically? This needs to be achieved through the PTZ control system. In Shenzhen Lean Technology Wireless Monitoring System, the pan-tilt control signal also needs to be transmitted through the wireless bridge, and it also needs reverse data transmission. In the analog wireless monitoring system, it is necessary to add a PTZ control receiver at the front end, and a PTZ control transmitter at the back end to implement PTZ control. The use of wireless bridges to transmit signals eliminates the need for separate transmission equipment to control the signals. Connecting the front-end signals to the wireless bridge enables remote pan-tilt control.
