The traditional elevator video surveillance system uses a wired transmission method, and often encounters the following problems when implementing elevator video surveillance:
1. Most of the elevator monitoring and wiring are bundled with other cables, but because the AC signals in other cables will leak out through the transmission cable, when the video cable and its long distance are bundled in parallel, they are equivalent to an "antenna". In this way, the interference signal will be coupled into the video signal, and a video interference phenomenon will occur.
2. Half of the elevators are used for extension. High-rise elevators can reach more than 100 meters. The weight of a 100-meter cable is nearly 100 kilograms. As the elevator moves up and down, the cable must be lost for a long time. Therefore, problems such as signal degradation may occur.
3. The interference of the power supply in the elevator is also very important. Use a clean power supply to prevent power supply interference. It is best to use a centralized power supply in the machine room to avoid power supply interference. The interference from the power supply into the video signal is also the most difficult interference problem.
Some customers will choose to replace the video cable to deal with the above problems. The cable will be replaced every time, which not only wastes labor costs, but also the stability of the video surveillance system is very poor.
In recent years, Shenzhen Laian Technology has launched an elevator wireless video transmission system, which solves the problem of elevator cable interference, and has a long service life and very good stability. It has flexible deployment, simple maintenance, low interference, and beautiful appearance. For easy installation. At the same time, the wireless audio and video transmission method effectively avoids the loss of monitoring pictures and audio caused by the elevator cable failure, which fundamentally improves a series of problems that elevator monitoring faces.
Shenzhen Laian Technology Elevator Wireless Video Surveillance Solution brings innovative elevator wireless monitoring experience to users. It has been successfully implemented in the construction of elevators in residential districts and buildings in many regions in China. Its stable, reliable, clear and smooth monitoring screen, Has won high recognition from users.
Recommended wireless monitoring equipment are: Analog wireless monitoring system using LA-PY680, digital wireless monitoring system using LA-5840 or LA-2415N wireless bridge to achieve.
