Does the infrared surveillance camera automatically alarm when someone enters the monitoring range?
This as long as your video recorder has this function can it? The general are brought, so you can find the above settings on the VCR
The camera itself does not work, through the acquisition card, or hard disk video recorder, you can detect the mobile body will alarm,
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.
