The rated voltage of the wire used for monitoring camera should be greater than the operating voltage of the line; The insulation of the conductor shall conform to the installation mode of the line and the environmental conditions of laying. The cross-sectional area of the conductor shall meet the requirements of power supply and mechanical strength.
Avoid wire connections when distributing wires. Except where a joint is necessary, the joint of the camera must be pressed or welded. The joint of the wire and the branch should not be subjected to mechanical force. The conductor in the tube shall not have a joint under any circumstances. If necessary, place the joint on the probe terminal of the junction box.
Wiring shall be installed horizontally or vertically in the building. The wiring shall be protected by casing (plastic or iron pipe, according to the technical requirements of indoor wiring). The ceiling wiring can be wired with metal hose, but it needs to be fixed, secure and beautiful.
The signal line should not be parallel to the high-power power line, let alone in the same tube. If due to environmental constraints, the line should be run parallel, stay away from more than 50cm.
The AC power supply of the alarm control box should be wired separately, and the camera should not be connected to the signal line and the LOW-voltage DC power line in the same tube. The installation of the AC power line should meet the electrical installation standards.
The wiring of the alarm control box to the ceiling requires that casing should be inserted into the wall or protected with iron pipe, so as to improve the anti-damage performance of the anti-theft system.
There are two kinds of pipe wiring: light wiring and dark wiring. The open pipe of the camera should be horizontal and vertical, neat and beautiful.
Surveillance camera is a semiconductor imaging device, with high sensitivity, anti-glare, small distortion, small volume, long life, anti vibration and other advantages. Surveillance camera security system. At present, the generation of images is mainly from THE CCD camera, but also can take out the stored charge to change the voltage, which has the characteristics of anti-vibration and impact and is widely used.
Colour camera: Suitable for identifying details of scenes, such as clothing or colour of scenes. The color increases the amount of information, which is generally thought to be 10 times that of black and white cameras.
Black and white camera: suitable for areas with insufficient light lines and areas where lighting equipment cannot be installed at night. When only monitoring the position or movement of scenery, the resolution of black and white camera is usually higher than that of color camera.
