What is electronic monitoring?
For monitoring camera wire, the rated voltage shall be greater than the working voltage of the line; the insulation of the wire shall comply with the installation mode of the line and the environmental conditions for laying. The cross sectional area of the conductor shall meet the requirements of power supply and mechanical strength.
The wiring shall be installed horizontally or vertically in the building. Wiring should be protected with casing (plastic or iron pipe, according to the technical requirements of indoor piping matching), the ceiling line can be used metal hose, but need to be fixed, safe and beautiful.
Wiring should be avoided as far as possible. In addition to the non connection, the camera must be joined by line or welding. The wire connection and the branch shall not be subjected to mechanical force. The wire worn in the pipe shall not be connected under any circumstances. If possible, place the joint on the terminal box and the probe terminal.
The signal line can not be parallel to the large power line, nor can it be worn in the same tube. If the environment is limited, parallel lines should be kept away from 50cm.5. alarm control box AC power should be alone line, the camera can not signal line and low-voltage DC power line in the same tube, AC power line installation should comply with electrical installation standards.
