What is anti-theft alarm system?

The anti-theft alarm system is a system that uses physical methods or electronic technology to automatically detect intrusion in the defense monitoring area, generate an alarm signal, and alert the on-duty personnel of the area where the alarm occurred, and display possible countermeasures. Anti-theft alarm system is an important facility to prevent robbery, theft and other accidents. In case of emergencies, the location of the incident can be accurately displayed in the security control center through sound and light alarm signals, so that emergency measures can be taken quickly. The anti-theft alarm system, together with the entrance and exit control system, closed-circuit television monitoring system, visitor intercom system and electronic patrol system, etc., constitute a security precaution system.

Anti-theft alarm system usually consists of three parts: detector (also called anti-theft alarm), transmission channel and alarm controller.

The alarm detector is composed of sensors and signal processing. It is a device composed of electronic and mechanical components used to detect intruders' intrusion. It is the key to the anti-theft alarm system, and the sensor is the core element of the alarm detector. The use of sensor devices with different principles can constitute alarm detection devices of different types, different uses and different detection purposes.
