A comprehensive security system includes a series of systems such as anti-theft alarm system, video surveillance system, access system, intercom system, and electronic patrol system, etc. The anti-theft alarm system plays a very important role in the entire security system.

The security industry has developed very rapidly in recent years, and as an important member of the security system, the anti-theft alarm system has also been rapidly developing, with continuous improvement in performance and an increasing number of users. What is an anti-theft alarm system?

1 The function of anti-theft alarm system

The anti-theft alarm system is a security protection system that uses physical methods or electronic technology to automatically detect intrusion behavior occurring within the security monitoring area. Once an intrusion behavior occurs, it will generate an alarm signal in the first time, reminding security personnel of the location where the alarm occurred. After an emergency occurs, the alarm location can be accurately displayed in the alarm monitoring center through sound and light alarm signals, making it easy to quickly take emergency measures.

2 Working mode of anti-theft alarm system

The anti-theft alarm system utilizes various functional detectors to provide overall protection for the surrounding area, space, environment, and people in the protected area. Once outsiders enter or dangerous situations occur, they can promptly alarm to minimize user losses. Specifically, it is achieved by using principles such as infrared detection, temperature sensing, smoke sensing, and magnetic switch closure to send an alarm signal to the anti-theft alarm control panel, achieving a fully enclosed prevention effect on household doors, windows, and balconies.

3 Composition of anti-theft alarm system

A simple anti-theft alarm system consists of an anti-theft alarm control panel, a keypad, a remote control, some detectors, etc.

The core of the anti-theft alarm system is the anti-theft alarm control panel. The anti-theft alarm control panel is mainly used to receive alarm signals from detectors and provide timely feedback. When an alarm occurs, the anti-theft alarm control panel will generate a high decibel alarm sound and automatically dial the alarm number or send the alarm signal to the alarm monitoring center after receiving the alarm signal. If an anti-theft alarm control panel with taking photo function is installed, it can also take photos of the on-site situation and send them to the user’s computer or phone via email and multimedia message.

Detectors are also an important component of anti-theft alarm systems. PIR motion sensors use infrared detectors. They are devices composed of sensors and signal processing, used to detect intruder intrusion behavior. They are composed of electronic and mechanical components and are the key components of anti-theft alarm systems, and sensors are the core components of PIR motion sensors.

If sensor components with different principles are used, different types, purposes, and detection purposes of alarm detection devices can be formed. For example, door contacts installed on doors and windows, smoke detectors and gas detectors installed on kitchen, etc., need to be selected according to the different needs of users.

The reason why detectors can achieve different effects mainly depends on the intelligent analysis software inside the detector. Technicians write different programs to make the detector have different functions, thereby meeting the needs of different users. Another advantage of this is that it can reduce false alarms. The principle is to use software programs to identify possible situations that may cause false alarms or missed alarms, such as hot air flow, wind, etc. Quantify interference signals such as small animals, and then program them into software to identify various false alarms, thereby reducing false alarms.

With the continuous development of technology, anti-theft alarm systems are gradually moving towards networking and intelligence. The network alarm system integrates simple single anti-theft alarm systems through PSTN, mobile network (4G), broadband (TCP/IP), and other methods, achieving multi-point and multi-level alarm modes. At the same time, the anti-theft alarm system is also linked with video surveillance systems, access systems, intercom systems, etc., forming a unified security platform.

As an important member of the security system, the anti-theft alarm system plays an important role in ensuring the safety of users’ lives and property. However, with the continuous improvement of user needs, only by continuously developing high-tech anti-theft alarm systems can we meet their needs.
