Discussion on the installation skills and issues of the dome camera

Hemispherical camera installations are generally used in very important places such as banks, hotels, office buildings, shopping malls, subways, and elevator cars. Has a strong concealment. To this end, many people are troubled to install the dome camera. Today, Xiaobian brings you the hemisphere camera installation skills and matters. Thank you for your attention!

For indoor venues, hemispherical cameras can be installed to meet the monitoring needs. Functionally, if you don't need 24-hour monitoring, use a normal dome camera; if you need 24-hour night monitoring mode, you can use an infrared dome camera (if the monitoring environment is 24 hours, then the ordinary hemisphere can be Satisfied; if the surveillance environment has a certain level of auxiliary light at night, then a low-light camera can also be used). As for the wide range of surveillance, you only need to configure the size of the camera lens according to your needs.

In addition to the functions of the ordinary gun camera, the hemisphere camera has the subjective advantages of convenient installation, beautiful appearance and good concealment. Although the installation and maintenance of the dome camera is simple, in order to achieve the perfect performance of the camera, to achieve the desired camera effect, to meet the needs of users, it is also necessary to grasp some key and important requirements and standards during the construction wiring, installation and commissioning process. The relevant precautions are briefly described below.

1. When designing the construction wiring, lay the cable of the appropriate size and diameter according to the distance from the front camera to the monitoring center; if the line is too long and the cable is too thin, the line signal attenuation is too large, which can not meet the demand of image transmission. As a result, the quality of the image viewed by the monitoring center is very poor. If the camera is powered by dc12v, the transmission loss of the voltage should also be considered, so as to prevent the camera from being unable to operate normally due to insufficient power supply to the front camera. In addition, when laying the power cable and the video cable, the pipe wiring should be separately routed, and the spacing should be more than 1 meter to prevent the transmission of power interference signals.

2, the dome camera is installed by indoor ceiling (special circumstances need to be installed when the outdoor should be specially treated), then in the installation process should pay attention to the ceiling material and bearing capacity, try to avoid strong electricity and strong magnetic field Environmental installation. Ceilings made of aluminum alloy and gypsum board should be fixed with thin wood or cardboard on the top of the ceiling to fix the bottom plate screws of the camera. This will make the camera securely fast and will not fall off easily. Otherwise, the camera will be replaced during future maintenance. Will damage the ceiling of the gypsum material, and the fixing is not strong, resulting in damage, causing customer resentment; if it is installed above the doorway of the building, you should also pay attention to whether there is water leakage in the ceiling, whether the rain will drip during the rainy season. To the camera and other factors.
