Anti-theft alarm technology development status and prospects

From the point of view of geographical development, the alarm system was first promoted in coastal economically developed areas in China and then radiated to the Mainland. From the perspective of the development of the alarm system network, the alarm system has experienced telephone networking, network networking, GSM/GPRS, 3G/4G. networking. Judging from the technical development of the alarm system, it has experienced improvements and changes in the specialization, intelligence, integration, and ease of use. With the continuous improvement of the home market, how is the status of anti-theft alarm technology applied? What will happen to the future development trend?

Anti-theft alarm technology application status The current technical development of anti-theft alarm system mainly focuses on the following points:

The use of the production port is more stable and reliable, such as improving the performance of the product against damage, anti-lightning surge, anti-jamming, etc.; adding more functions to facilitate the installation and use, such as the adjustable frequency of the detector, the detection area can be set, and the anti-blocking , Anti-vandalism, wireless connection between the detector and the host, etc.; more convenient installation and debugging, wireless connection between the detector and the host, simplify installation and construction workload, and meet the needs of various home users.

Towards a more intelligent direction, such as adding regional management, voice reminding, deployment and removal of biometrics, automatic sending of MMS pictures by alarm, remote control, and other technologies; more networking methods, such as the expansion from a single telephone network to IP Networked networking, wireless GSM/GPRS networking, VPN dedicated line networking, etc.; through network encryption technology, data can be secured more securely, and master and slave backup functions between wired and wireless networks can be used to make the transmission of alarms faster. More reliable, more powerful integration and extensibility, command output of multiple alarm contents, linkage with other devices such as video surveillance, access control, etc. to realize coordination and unification between systems, making alarm security more automatic and intelligent, and further preventing security. improve.

Poor detection accuracy The detection accuracy of the anti-theft alarm system mainly depends on the front-end detector. Due to the limitations of detection technology, various detectors have their own insurmountable defects. For example, widely used passive infrared detectors, the detection principle is based on all objects. Different levels of infrared are emitted. The detector detects the movement of the infrared-emitting object, but when the temperature of the target to be detected is very close to the ambient temperature or the moving object wears a thermal insulation clothing, the passive infrared detector is basically in a state of failure. The probability of missed reports has greatly increased. Another example is a single microwave detector. Because of the strong penetration of microwaves, objects that move outside the wall often affect the detector, so its false alarm rate will be much higher. Active infrared detectors may also be affected by reflected light from the surrounding area, resulting in missing reports. Therefore, in order to eliminate false reports, in addition to constantly improving the quality of products and technology, there is also a way to install detectors with different detection technologies in places to be protected, such as vibration detectors, air pressure detectors, and microwave-infrared pairs. With the simultaneous use of detectors and sound intensity detectors, one of the techniques can make up for the defects in other detection techniques. Overlapping installations can be used to complement each other and eliminate missing reports.

Anti-theft alarm system development prospect The most basic function of the anti-theft alarm system is to defend the collective and individual's life and property safety, and achieve social stability and harmony. With the development of society and economic prosperity, with the improvement of people’s safety awareness, anti-theft alarm system products and their related products will inevitably spread to every family, and will be composed of family security through socialized and market-oriented management methods. Electronic systems or networks for prevention and anti-theft alarm handling.

Establishing and strengthening the construction of a social networking home burglar alarm system is the best way and important means to deal with the increasingly complex social situation, especially the tiers and comprehensive solutions to burglary and robbery cases, and weave the socialized prevention network. The actual needs for building a "Safe City" are an effective way to integrate policing security resources, improve the level of urban prevention and control, and promote the sustainable development of safety technology prevention and management work. The electronic alarm system and network management are the best form of human-technology integration for family prevention and control in the new era, which can effectively improve the scientific and technological content of family prevention and control and the technical content of socialized scientific management. China is the most populous country in the world. If it spreads to home users, whether it is the alarm host, detector or other equipment, or the security service operation center, its market has huge potential and it has great development prospects.
