Do you often encounter similar problems during the installation process? Irregular monitoring installations may lead to these problems, so here are the factors that you should pay attention to while installing a surveillance system.
Installation Position Selection
The position selected should be suitable for the installation, use, and maintenance of the camera as follows judgment basis:
- The camera installation position should be away from any high-voltage cables.
- The camera installation position should not be easily affected by external interference or damage with a stable and firm mounting bracket.
- The installation position should prevent the camera from blocking by road signs or branches.
- The installation location should avoid low-lying areas to prevent equipment from being submerged
- Outdoor cameras should be equipped with lightning protection equipment and with nearby grounding devices.
- The signal transmission line must maintain a distance of at least 450mm from high-voltage equipment or cables.
- Wires with different electricity power levels cannot be bundled and routed within the same pipe.
- Route the outdoor wiring along and under the eaves if possible.
- For open areas, pipes must be steel sealed and routed in a buried way, also grounded at one point. Overhead wiring is prohibited.
- When the installation adopts an L-shaped pole, the crossbar should take a certain upward angle to prevent rainwater from pouring down to the top of the camera due to the poor sealing of the crossbar.
- Pay attention to the waterproof treatment of the wiring joint and terminal to prevent abnormal imaging due to corrosion. The outlet of a wall-mounted camera with side wiring has to be facedown, also place the power adapter in a distribution box.
- While installing a dome camera, avoid transporting by the output cable of the portable dome camera to prevent loosening of the waterproof part and deterioration of the waterproof performance. While installing a threaded bracket, do not connect the wire before the rotating installation to prevent stranded wires, cables damage, and abnormal signal.
Lightning protection and grounding
- To maximize the lifetime of equipment, the camera, pole, front-end chassis, and others equipment should be grounded.
- If the camera is installed on a concrete pole or wall, it needs to be earthed nearby; if the camera is installed and well-connected on a metal pole, it can be earthed indirectly via the metal pole.
- Install additional high-power lightning protection equipment and lightning rods in severe thunder storming or high-voltages induced areas such as high-voltage substations
Having said so many precautions, we are going to explain specific actual scenes and situations that installers may encounter during installation in the next article. Stay tuned!
