Due to its beautiful appearance and good concealment performance, dome cameras are widely used in banks, hotels, office buildings, shopping malls, subways, elevator cars and other places that require monitoring, pay attention to beauty, and pay attention to concealment. Needless to say, installations are naturally also possible in ordinary indoor environments, depending on individual needs and camera functions.
All indoor places can choose to install dome cameras to meet the needs of monitoring. Functionally, if you don’t need 24-hour monitoring, use an ordinary hemisphere camera; if you need a 24-hour night-and-day monitoring mode, you can use an infrared hemisphere camera (if the monitoring environment is brightly lit 24 hours a day, then an ordinary hemisphere can Satisfaction; if the surveillance environment has a certain degree of auxiliary light source at night, it is also possible to use a low-light camera). As for the scope of monitoring, you only need to configure the size of the camera lens according to your needs.
In addition to the functional indicators of ordinary bullet cameras, the dome camera also has subjective advantages such as convenient installation, beautiful appearance, and good concealment. Although the installation and maintenance of the dome camera is simple, in order to exert the perfect performance of the camera, achieve the ideal camera effect, and meet the needs of users, it is also necessary to grasp some key and important requirements and standards in the process of construction wiring, installation and debugging. The relevant precautions are briefly described below.
（1）When designing and constructing wiring, a cable of suitable size should be laid according to the distance from the front-end camera to the monitoring center; if the line is too long, the cable used is too thin, and the line signal attenuation is too large, which cannot meet the needs of image transmission. As a result, the quality of the images viewed by the monitoring center is very poor; if the camera is powered by DC12V centralized power supply, the transmission loss of the voltage should also be considered, so as to avoid the insufficient power supply of the front-end camera and the camera cannot be used normally. In addition, when laying power cables and video cables, they should be routed through pipes, and the spacing should be more than 1 meter to prevent the power supply from interfering with signal transmission.
（2）The dome cameras are installed on the indoor ceiling (in special cases, special treatment should be done when installing outdoors), then during the installation process, you should pay attention to the material and load-bearing conditions of the ceiling, and try to avoid strong electricity and strong magnetic fields. Environment installation. For the ceiling made of aluminum alloy and gypsum board, during the installation process, thin wood or cardboard should be added to the top of the ceiling to fix the bottom plate screws of the camera, so that the camera can be fixed firmly and will not fall off easily. Otherwise, the camera will be replaced in the future maintenance process. It will damage the gypsum ceiling, and it will not be fixed firmly, which will cause damage and cause disgust from customers; if it is installed above the corridor outside the door of the building, you should also pay attention to whether there is water leakage in the ceiling, and whether the rain will shower in the rainy season. to the camera, etc.
