Simple understanding: basic structure of burglar alarm:

The burglar alarm system is an important facility to prevent accidents such as robbery and theft. In the event of an emergency, the location of the incident can be accurately displayed in the security control center through the sound and light alarm signal, so that emergency measures can be taken quickly. The anti-theft alarm system together with the entrance and exit control system, the closed-circuit television monitoring system, the visitor intercom system and the electronic patrol system constitute a security system.

The burglar alarm system usually consists of three parts: a detector (also called an alarm), a transmission channel, and an alarm controller.

The alarm detector is composed of sensors and signal processing. The device consisting of electronic and mechanical components for detecting intruder intrusion is the key to the anti-theft alarm system, and the sensor is the core component of the alarm detector. Sensors with different principles can be used to construct alarm detection devices of different types, different purposes and different detection purposes.
