1. Most of the monitoring and cabling for elevators use the method of bundling with other cables. However, since AC signals in other cables will leak out through the transmission cable, video cables will also be equivalent to an "antenna" if they are bundled in parallel over long distances. , This interference signal will be coupled into the video signal, video interference phenomenon.
2. Half of the elevators are used for extensions. The high-rise elevators can reach more than 100 meters. The self-weight of a 100-meter cable is nearly 100 kilograms. As the elevator moves up and down, the cable must be worn out for a long time. Therefore, there will be problems such as signal deterioration.
3. The interference of the power supply in the elevator is also very important. To use a clean power supply to prevent power interference, it is best to use centralized power supply in the equipment room to avoid power interference. Interference from the power supply into the video signal is also the most difficult problem to solve.
Some customers will choose to replace the video cable to deal with the problem in 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 Lai'an Technology has launched an elevator wireless video transmission system that solves the problem of elevator cables being disturbed, has a long service life, and is very stable. It has flexible deployment, simple maintenance, low interference, and beautiful appearance. Easy to install. At the same time, the wireless audio and video transmission method effectively avoids the loss of monitoring pictures and audio due to the failure of elevators with the cable, and fundamentally improves a series of problems faced by elevator monitoring.
Shenzhen Lian Technology Elevator Wireless Video Surveillance Solution brings innovative elevator wireless monitoring experience to users. It has been successfully implemented in the elevator construction of residential districts and buildings in many regions in China. It has stable, reliable, clear and smooth monitoring images. Has won the user's high recognition.
Recommended wireless monitoring equipment: analog wireless monitoring system using LA-PY680, digital wireless monitoring system using LA-5840 or LA-2415N wireless network bridge to achieve.
