Secondly, the installation of surveillance equipment needs to determine the number of cameras to be installed, and to determine the scope of surveillance and image quality of each camera. First decide to monitor the number of cameras, and then according to the specific situation to determine the camera's lens monitoring range: it must be clear that the distance from the camera to the monitoring point and the need to monitor the area, as for the clarity, we believe that: 480 TV lines of the camera has been sufficient.
Third: whether to have night vision. If your monitoring equipment is installed in corridors, foyers, aisles, warehouses and other dark places, you can consider the infrared night vision function of the camera, it should be noted that the infrared camera in addition to professional night vision or special order, infrared cameras also need to be on-site with lighting to assist the five fingers of the conditions of the infrared distance will be exponentially shortened. Site if the garden lawn, infrared effect is worse.
Fourth: is the direct wiring or wireless transmission to install. In addition to the expensive price, the wireless network does save the camera installation trouble and unattractive, but need to pay attention to the distance and obstacles. In principle, the cement building materials will shorten the wireless transmission distance, metal materials will completely block the wireless signal, transmitter (at the camera end) and receiver (at the host end) to avoid interference away from other electrical appliances, such as the use of wireless networks, we must have a burden of more than two times the price of the monitoring equipment. We recommend using wired transmission for installation unless necessary.
Fifth: site monitoring and network monitoring you to determine the monitoring system installation, to consider whether the need for network functionality, that is, if you need to monitor the site at any time in the Internet monitoring and control, you need to choose the network function of the monitoring host. Avoid the installation but no network transmission function.
Surveillance camera installation method:
1) In order to meet the requirements of the monitoring target field of view range of conditions, its installation height: indoor off the ground should not be less than 2.5m; outdoor off the ground should not be less than 3.5m.
2) Surveillance cameras and their supporting devices, such as lenses, camera guards, brackets, windshield wipers, etc., the installation should be firm, the operation should be flexible, should be careful to prevent damage, and with the surrounding environment. Attention to anti-vandalism, and coordination with the surrounding environment.
3) In a strong electromagnetic interference environment, the monitoring camera installation should be isolated from the ground insulation.
4) Signal lines and power lines should be introduced separately, the exposed part of the hose protection, and does not affect the rotation of the head.
5) The monitoring camera in the elevator compartment should be installed on the left or right side of the compartment above the door, and can effectively monitor the facial features of the elevator compartment occupants.
The installation of the head and decoder:
1) The installation of the head should be firm, and there is no shaking when rotating.
2) According to the technical conditions of the product and system design requirements, check whether the rotation angle range of the head meets the requirements.
3) The decoder should be installed near the head or in the ceiling (but there must be access holes).
Surveillance camera control equipment installation:
1) Console, cabinet (rack) installation location should meet the design requirements, the installation should be stable and solid, easy to operate and maintain. (Cabinet rack) back, side net distance from the wall should meet the maintenance requirements.
2) Surveillance cameras, all control, display, recording and other terminal equipment installation should be smooth, easy to operate. One of the monitor (screen) should avoid direct external light, when unavoidable, light avoidance measures should be taken. In the console, cabinet (rack) installed in the equipment should be ventilated cooling measures, internal connectors and equipment should be firmly connected. 3) control room all cables should be set according to the equipment installation location of the cable groove and into the hole, arranged, bundled neatly, numbered, and have a permanent sign
