The layout is reasonable, neat, and the installation is firm. The technical requirements are as follows:

1. The wire used to install the surveillance camera should have a rated voltage greater than the working voltage of the circuit; the insulation of the wire should conform to the installation method of the circuit and the environmental conditions of the laying. The cross-sectional area of the wire should be able to meet the requirements of power supply and mechanical strength.

2. When installing the surveillance camera wiring, try to avoid the wires with joints. Unless it is impossible to use a connector, the connector of the camera must be crimped or welded, and the wire connection and branch should not be subjected to mechanical force. The wires in the tube should not have connectors under any circumstances. If necessary, put the connectors on the probe terminal of the junction box as much as possible.

3. Install the surveillance camera wiring in the building to be installed horizontally or vertically. The wiring should be protected by sleeves (plastic or iron water pipes, optional according to the technical requirements of indoor piping), and metal hoses can be used for ceiling wiring, but they need to be fixed and secure.

4. The signal line of the surveillance camera cannot be parallel to the high-power power line, let alone run in the same tube. If due to environmental constraints, the wires should be routed in parallel, and the distance should be more than 50cm.

5. The AC power supply for the alarm control box of the surveillance camera should be routed separately. The camera should not be placed in the same tube with the signal line and low-voltage DC power cord. The installation of the AC power cord should comply with electrical installation standards.

6. The wiring from the alarm control box of the surveillance camera to the ceiling is required to be managed in the wall or protected by iron pipes to improve the anti-destructive performance of the anti-theft system. Technical requirements for indoor piping of the camera

7. There are two types of wiring and tube wiring for the installation of surveillance cameras: open and dark. The piping of the camera is required to be horizontal and vertical, neat and beautiful. Concealed piping requires short, unobstructed, and few elbows.
