Zhongwei HD monitoring system IP address is not how to do
Also may also be connected to the camera cable disconnection (usually bad contact or broken network), or the camera power cord circuit (the same as above), check
Does the infrared surveillance camera automatically alarm when someone enters the monitoring range?
General camera is not the end of the low-end camera does not have this function, you can use the alarm to linkage, the alarm through the infrared detection of some people come in, will alarm. There is an automatic monitoring area of the camera can be, once someone appears in a certain area will be the alarm, similar to the road to shoot the kind of red light. Very sensitive, but the cost is relatively high. The best infrared camera can find 300 meters of people, but it is expensive.
What is the difference between a dome camera, a gun camera and a dome camera in security monitoring?
Hemisphere is generally installed ceiling, the bolt is installed on the wall, whether with infrared light, the size of the lens according to the actual situation and customer requirements to consider. The dome can be rotated 360 degrees, set the preset position can be automatically cruise, you can automatically zoom to the center of the scene picture auto focus, keep the image clear, you can also manually focus.

In some applications, the field of view can contain a very bright area, and the subject is included in the bright field surrounded by a picture of a bleak, no level. At this point because the AGC detects the signal level is not low, so the amplifier gain is very low, can not improve the brightness of the main screen, when the introduction of backlight compensation, the camera only the entire field of view of a sub-region, Area of the uniform signal level to determine the AGC circuit operating point.
