Security monitoring How to wire the installation of engineering camera
During the installation of security monitoring project video camera The image generation in the security system is currently mainly from the camera. The installation safety of cameras in the security monitoring project has always been concerned, especially in the wiring. Then, how to wire the indoor installation of the surveillance camera in the surveillance project?
1. The rated voltage of the wire for the monitoring camera shall be greater than the working voltage of the line; The insulation of the conductor shall comply with the installation method and laying environmental conditions of the line. The cross-sectional area of the conductor shall meet the requirements of power supply and mechanical strength.
2. When wiring the monitoring camera, try to avoid any connector on the wire. Unless it is impossible to use a connector, the camera connector must be crimped or welded, and the wire connection and branch shall not be subject to mechanical force. Under no circumstances should there be any connector for the empty wire in the pipe. If necessary, the connector should be placed on the terminal of the probe in the junction box as far as possible.
3. The wiring of the surveillance camera shall be installed horizontally or vertically in the building. The wiring shall be protected by casing, and the ceiling wiring can use metal hose, but it shall be fixed securely and beautifully.
4. The signal line of the security monitoring camera cannot be parallel to the high-power power line, nor can it be threaded in the same pipe. If parallel wiring is required due to environmental constraints, it should be kept away from more than 50cm.
5. The AC power supply of the alarm control box of the monitoring camera shall be routed separately. The camera cannot be threaded in the same pipe with the signal line and low-voltage DC power line. The installation of the AC power line shall comply with the electrical installation standards.
6. The wiring from the alarm control box of the surveillance camera to the ceiling shall be jacketed into the wall or protected with iron pipes to improve the vandal resistance of the anti-theft system.
7. Technical requirements for indoor piping of surveillance camera: there are two types of camera conduit wiring: open and concealed. The exposed piping of camera shall be horizontal and vertical, neat and beautiful. The concealed piping shall be short, smooth and with few elbows.
