The dome camera has the subjective advantages of convenient installation, beautiful appearance and good concealment, in addition to the indicators on the function of ordinary gun cameras. Although the installation and maintenance of the dome camera is simple, in order to display the perfect performance of the camera, achieve the ideal camera effect, and meet the needs of users, it also needs to grasp some key and important requirements and standards in the process of construction wiring, installation and debugging. The relevant notes are briefly described below.
1. When designing the construction and cabling, it is necessary to lay cables of appropriate size according to the distance from the front-end camera to the monitoring center; if the lines are too long and the cables used are too thin, the signal attenuation of the lines is too large to meet the requirements of image transmission. As a result, the quality of the image viewed by the monitoring center is very poor. If the camera uses a DC12V centralized power supply, the transmission loss of the voltage should also be taken into account so as to prevent the camera from being unable to operate normally due to insufficient power supply from the front camera. In addition, when laying power cables and video cables, they must be routed separately and at a distance of more than 1 meter to prevent transmission of power interference signals.
2. The dome cameras are installed by indoor ceilings (special circumstances require special treatment when installed outdoors). During the installation process, attention should be paid to the materials and load-bearing conditions of the ceiling, and strong electric fields and strong magnetic fields should be avoided as much as possible. Environmental installation. Aluminum alloy and gypsum board ceilings should be installed at the top of the ceiling with thin wood board or cardboard to fix the camera floor screws, so that the camera can be fixed firmly and will not easily fall off, otherwise, replace the camera in the future maintenance process It will damage the ceiling of the plaster material, and it will not be firmly fixed, which will cause damage and cause annoyance to customers. If it is installed above the corridor outside the building, you should also pay attention to whether there is water leakage in the ceiling, and whether rain will shower during the rainy season. To camera and other factors.
Dome camera installation operation guide!
In indoor areas, hemisphere cameras can be installed to meet the monitoring needs. Functionally speaking, if you do not need 24 hours of monitoring, use an ordinary dome camera; if you need 24-hour nighttime surveillance mode, you can use infrared dome camera (if the monitoring environment is 24 hours brightly lit, then the ordinary hemisphere can be Satisfaction; if the surveillance environment has a certain degree of auxiliary light at night, then low-light cameras can also be used). As far as the scope of monitoring is wide and narrow, you only need to configure the camera lens size according to your needs.
