How GSM burglar alarm system works

May 21, 2018

To introduce the working principle of the GSM anti-theft alarm system, first of all to introduce the concept of GSM anti-theft alarm, GSM anti-theft alarm system using the global GSM short message data transmission mode and voice function into intelligent data remote transmission and control alarm. The system integrates smart home functions such as home, store and office space security, electrical appliances control, remote monitoring of private cars, etc. Since the GSM global wireless mobile communication network covers a wide area of signals, it has realized ultra-long-distance convenience with low price and high quality. Flexible smart wireless controls and alarms solve the limitations of wired alarms in fixed telephone or cable broadband networks. The GSM global wireless mobile communication network has spread throughout the world and is widely used in security devices, data monitoring, and remote monitoring systems in single-family, residential property, power, transportation, petroleum, coal, railway, municipal, and public security sectors.

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

Alarm detector is composed of sensors and signal processing. It is used to detect intruder intrusion. The device consisting of electronic and mechanical components is the key to the anti-theft alarm system. The sensor is the core component of the alarm detector. The use of different principles of the sensor components, can constitute different types, different uses, to achieve different detection purposes of the alarm detection device.

(1) Alarm detectors can be divided into infrared alarm detectors, microwave alarm detectors, passive infrared/microwave alarm detectors, glass broken alarm detectors, vibration alarm detectors, ultrasonic alarm detectors, laser alarm detection according to the working principle. , magnetic switch alarm detectors, switch alarm detectors, video motion detection alarms, sound detectors and many other types.

(2) Alarm detectors can be classified into active alarm detectors and passive alarm detectors according to their working methods.

(3) Alarm detectors can be classified into point-controlled alarm detectors, line-controlled alarm detectors, surface-controlled alarm detectors, and space-prevention alarm detectors according to different detection ranges.

In addition to the above distinction, there are other ways of dividing. In practical applications, different types of alarm detectors can be reasonably selected to meet different security requirements according to different usage conditions.

The alarm detector is used as a sensor detection device to detect the intruder's intrusion behavior and various abnormal conditions. There are many places where security precautions are required in various smart buildings and ordinary buildings. These sites also have various safety precautions and requirements depending on the actual situation. Therefore, a variety of alarm detectors are required to meet different security requirements.

According to the actual site environment and the user's security requirements, a reasonable selection and installation of various alarm detectors can better achieve the purpose of security. When choosing and installing an alarm detector is not appropriate, there may be loopholes in security precautions, failing to meet the strictness of security precautions and creating an opportunity for intruders, thus bringing undue losses to the security protection work.
