The infrared alarm uses the transmitter to launch infrared rays, and the receiver receives infrared to work.A infrared alarm line is formed between the transmitter and the receiver. Under normal circumstances, the transmitter launch infrared rays, and the receiver receives a stable light signal.And once the alarm prevention is invaded, the infrared beams emitted by the transmitter are blocked, and the receiving machine receives no longer a stable light signal, but a certain degree of changes.To the alarm controller so that they will send a alarm signal.
Infrared alarm repair
For this kind of problem, youd better find a professionals to repair you to repair you, so as not to buy it because of a small loss.The following is a reference method for you: infrared against shooting is a very simple anti -theft product, bad possibility components, power supply parts, relay parts.Of course, this thing has a life span.
Infrared alarm anti -theft
The infrared alarm is divided into two types: active and passive.The active infrared alarm is to actively emit infrared the alarm. When the infrared rays meet the obstacles, they will rebound back and receive the probe of the alarm.If the probe is monitored, the infrared rays are restless, that is, the red line is constantly emitting the red line, and the alarm will not call the police.When a moving object violates this invisible red line, the probe will detect abnormalities and report to the police.The passive alarm is less function, that is, the emission of infrared.Physics tells us that when the temperature of an object is 0K, infrared rays will be emitted, and in other words, any object can emit infrared.The subsequent principles, passive alarms are the same as active.
Infrared alarm installation
Many users do not know how to install the products in a fixed location. In fact, the products have a instructions.
