When installing security monitoring equipment, the third consideration is whether the camera has night vision function. If the monitoring is installed in a relatively dark place, it is necessary to consider using a camera with infrared night vision function.
On-site monitoring and network monitoring When determining the installation of the monitoring system, you should consider whether network functions are required. That is to say, if you need to monitor and control the monitoring site at any time on the Internet, you need to choose a monitoring host with network functions. Avoid the installation is complete but there is no network transfer function.
A complete security monitoring equipment must have at least three parts: surveillance camera, pan/tilt, and decoder. The following is their installation method:
The installation method of surveillance camera:
1. In a strong electromagnetic interference environment, the installation of the surveillance camera should be isolated from the ground.
2. Under the condition of meeting the requirements of the field of view of the surveillance target, the installation height should not be lower than 2.5m indoors and 3.5m outdoors.
3. The surveillance camera in the elevator car should be installed on the left or right side above the car door, and can effectively monitor the facial features of the passengers in the elevator car.
4. Surveillance cameras and their supporting devices, such as lenses, camera shields, brackets, wipers, etc., should be firmly installed, flexible in operation, and should be protected from damage and coordinated with the surrounding environment.
5. The signal line and power line should be introduced separately, and the exposed part should be protected by a hose, which does not affect the rotation of the gimbal.
Installation of surveillance camera control equipment:
1. All cables in the control room should be set with cable troughs and cable entry holes according to the installation location of the equipment, arranged, bundled neatly, numbered, and have permanent signs
2. The installation position of the console and the cabinet (rack) should meet the design requirements, and the installation should be stable and firm, easy to operate and maintain. The clear distance from the back and side of the cabinet frame) to the wall should meet the maintenance requirements.
3. The installation of all control, display, recording and other terminal equipment of the surveillance camera should be stable and easy to operate. Among them, the monitor (screen) should avoid direct external light, and when it is unavoidable, measures should be taken to avoid light.
The equipment installed in the console and cabinet (rack) should have ventilation and heat dissipation measures, and the connection between the internal connector and the equipment should be firm.
PTZ and decoder installation:
1. According to the product technical conditions and system design requirements, check whether the rotation angle range of the gimbal meets the requirements.
2. The installation of the gimbal should be firm, and there is no shaking when rotating.
3. The decoder should be installed near the pan/tilt or in the ceiling (but there must be access holes).
