On the basis of the widely
application of surveillance cameras and the installation of security
monitoring equipment, why are there frequent incidents of theft in life. It
was known that it was because the monitoring had a dead angle after the investigation.
The thief deliberately avoided the surveillance area and entered the
surveillance blind zone for theft. But the Cctv Camera did not monitor the
theft. So when people face a variety of complex environments and the
monitoring device has a dead angle, is there any way to avoid
risks?
The general security camera type
includes a network ip camera and PTZ IP camera. The back end is generally
equipped with a HD NVR as a video storage management device, and an analog HD
camera has a DVR configured at its back end. Security camera are typically
equipped with fixed lens, varifocal lens, and motorized zoom lens
IP camera. At present, the market is mainly divided into bullet
cameras, dome cameras and 360-degree panoramic high-speed cameras. Among
them, the bullet camera is more common, suitable for indoor and outdoor video
surveillance; the dome camera is generally used indoors and the volume is
small; the 360 degree panoramic security dome camera is generally suitable
for large outdoor environments, such as streets, squares and stations. Wall
mounting or ceiling mounting is available depending on the installation
environment or monitoring requirements.
Surveillance Camera Installation Method: 1. In the case of
strong electromagnetic interference, the surveillance camera installation
should be insulated from the ground. 2.Under the condition of meeting the
requirements of the monitoring target field of view, the first consideration
is the installation location, in order to enable the camera to avoid
interference from the surrounding environment, to achieve a better video
capture and survival effect. When installing indoors, we should ensure that
the height of the equipment is not less than 2.5 meters, and in the outdoor
environment, we should also place the monitoring equipment at a height of
more than 3 meters from the ground. Make sure the camera is not maliciously
damaged. 3. Regarding the installation of the elevator security camera, the
first thing to consider is the interference problem, followed by the wiring
problem, and the third need to consider the power supply. From our daily
experience, the camera in the elevator car should generally be installed
diagonally on the upper left or upper right of the elevator car door. The
lens is generally fixed lens 2.8mm, and can effectively monitor the facial
features of the occupants in the elevator car. 4, surveillance camera and its
supporting devices, such as lens, camera shields, brackets, wipers, etc., the
installation should be firm, the operation should be flexible, should pay
attention to anti-destruction, the camera installation should be coordinated
with the surrounding environment. 5. The camera signal cable and power cable
should be introduced separately. The exposed part of the cable is protected
by a hose and does not affect the rotation of the tripod head.
