Analog Surveillance System Uses Wireless Bridge How to Transmit
Many construction sites have built a complete set of analog wireless monitoring systems, but they also want to transmit the entire surveillance system image to another place via wireless. If it is a normal environment and no shelter, it can be transmitted directly using analog wireless transmission equipment. However, due to the proximity of railways or other facilities, it is still recommended to use wireless bridges for transmission. Because the simulated equipment is susceptible to interference.
Taking a construction site as an example, there are nine analog cameras at the front end, which are connected to the site monitoring room by optical fibers. Now I want to transmit these 9 video signals to another monitoring room. I have separated the railways by trains. Railways have various sources of interference, so it is not practical to use analog wireless transmission equipment directly, and it can only be implemented in the form of a wireless bridge. A distance of no more than one kilometer can be used to transmit with the LA-5830F wireless bridge in Lai'an. Signals must be converted. The signal from the optical transceiver is connected to two 4-way encoders and one 1-way encoder. Then use the switch to concentrate the signal from the encoder and then use a LA-5830F wireless bridge to transmit the signal. In the new monitoring room, a LA-5830F wireless bridge was used to receive the signals from the old monitoring room, and then connected to the switch. The signals coming out of the switch were converted into analog signals by 9 single-channel decoders. After connecting to the DVR, store it and display it on the wall.
After such transmission, there is no need to destroy the original monitoring system, and no wiring is required, which will not affect the environment. Using a 5.8G-band wireless bridge can effectively avoid some common interferences. The entire transmission is also very stable, convenient and simple. However, attention should be paid to the following: As there is a road between the old monitoring room and the new monitoring room, there may be a train passing through. Therefore, the altitude must be set higher than the height of the train to avoid the obstruction.
