When most elevators are not in use, the fluorescent lamps inside the car are energy-saving. If you need to monitor the cabinet for 24 hours, you can choose infrared dome cameras. Otherwise, you can select an ordinary dome camera (when someone enters the elevator car). The time light will turn on automatically). Because the elevator car is very short, it is inevitable to artificially destroy the equipment. At this time, users can choose explosion-proof dome cameras.
The elevator is a carrier with complicated environment. The motor outside the car and the power supply will generate huge interference signals when it is running. The disturbance of the monitored video signal is naturally a problem often encountered by the engineering companies. How to avoid it?
Firstly, from the equipment selection, the engineering contractor and the user should try to use the mature equipment on the market and the hemisphere camera with strong anti-interference ability for elevators. At the same time, use elevator-dedicated cables during wiring, taking care not to damage the cables. In the power consumption of the camera, the monitoring power interface reserved by the elevator is used as much as possible to prevent accidental leakage accidents. In normal mode, the interference problem cannot be solved, and anti-jamming measures can be taken in the transmission line.
At present, most elevator monitoring systems use the wired transmission mode of analog signals. The connection is displayed on the display platform of the monitoring room. There is no special requirement for the position of the display. The display is displayed in a conspicuous and easy-to-view position according to the user's requirements. You can.
Due to the small elevator space and crowded personnel, in the event of accidental rescue difficulties, when installing surveillance cameras, it is necessary to pay more attention to the strict operation procedures and installation specifications; it is impossible to randomly connect and unrelated cables, and the interfaces of the lines must comply with the specifications. Can not be arbitrarily overlap; use the product quality to be as reliable as possible (such as: cameras, transformers, cables, etc.), have relevant test reports and certificates. In this way, it can reduce the occurrence of various types of accidents.
In addition, the longer the video line, the greater the possibility of clutter signals interfering with the video, and the quality of the video signal transmission will be degraded; in some large industrial areas, where the need for centralized monitoring, this analog signal transmission The system will lose its function. At this time, engineers and users can use digital signal transmission mode to reduce signal interference and simplify wiring, or use wireless transmission to eliminate the cumbersome construction wiring.
