Installation process of surveillance cameras

1. The rated voltage of the wire used for surveillance cameras should be greater than the working voltage of the line; the insulation of the wire should comply with the installation method of the line and the environmental conditions of the laying. The cross-sectional area of ​​the wire should meet the requirements of power supply and mechanical strength.
2. When wiring, try to avoid wire joints. Except for the joints that must be used, the joints of the camera must be crimped or welded, and the wire connections and branches should not be subjected to mechanical forces. The wires in the pipe must not have joints under any circumstances. If necessary, the joints should be placed on the probe terminals of the junction box as much as possible.
3. The wiring should be installed horizontally or vertically in the building. The wiring should be protected by a casing (plastic or iron pipe, selected according to the technical requirements of indoor piping). Metal hoses can be used for ceiling wiring, but they must be fixed, stable and beautiful.
4. The signal line cannot be parallel to the high-power power line, let alone in the same pipe. If the environment limits the parallel wiring, it should be kept at least 50cm away.
5. The AC power supply of the alarm control box should be routed separately. The camera cannot be placed in the same pipe with the signal line and low-voltage DC power line. The installation of the AC power line should comply with the electrical installation standards.
6. The wiring from the alarm control box to the ceiling requires a set of management inside the wall or protected by an iron pipe to improve the anti-destruction performance of the anti-theft system.
7. There are two types of wire pipe wiring: open wiring and concealed wiring. The open pipe of the camera is required to be horizontal, vertical, neat and beautiful.
