As an indispensable part of the security system, the alarm system always stands at the forefront of the security industry with its unique space and environmental detection and prevention technology and the timeliness of protection. The anti-theft alarm system started in the late 1980s in China. It was a period of rapid development around 2000. Since then, the anti-theft alarm industry has continued to develop. With the continuous development of China's security industry, people's awareness of security continues to increase With the rapid growth of the civil market share, a new round of development has been ushered in the field of burglar alarm.
The development of the application and technical level of the alarm system and the continuous trend of future products will now be briefly explained.
1.Communication
Its main performance is in the network-type alarm system, domestic applications such as security service companies around the country, 110 alarm platform, major banks and so on. Until now, most of the original alarm networking system still used the PSTNdian telephone line to report the Jing method. The dian telephone system will have great disadvantages in application, such as cost or line problems.
With the development of Internet technology, the alarm system has gradually been digitized. The modern alarm center will be a networked and digital alarm center. The front-end alarm signal is transmitted to the alarm center through TCP / IP. The advantages are fast response time, large capacity, non-blocking, wide range and low cost. It can also realize remote management and inspection through the network. It is a digital alarm in the future. The first xuan of the center. You can also use GSM / GPRS and other methods, use ordinary SIM card to enable GPRS function, you can send alarm information through wireless mobile network.
The digital alarm system is also compatible with the traditional PSTNdian telephone line dialing jing mode, and can achieve mutual backup with TCP / IP, GSM / GPRS and other methods, and coexistence of multiple communication methods. Ensure the normal transmission of alarm messages.
2. Development of detection technology
The alarm system not only requires the stability and functionality of the control host, it is important to detect the front-end detection equipment, including various types of detectors, such as dual detectors, infrared detectors, glass break detectors, vibration detectors, etc. . In the alarm system, the detector plays the most important role. It is necessary to ensure that false alarms and false alarms are avoided.
In terms of technology, various manufacturers are also making technical updates, such as upgrading of microwave frequency bands, anti-radio frequency interference, anti-fluorescent interference, digital signal processing, and temperature compensation for passive infrared detection.
3. System integration
The security subsystems or other systems need to be set up in linkage with each other. The traditional method is to realize switching signal output through a relay module, which requires tedious wiring between hardware, and the linkage is fixed and cannot be changed. In the future, it will become a development trend through software integration. Various systems are concentrated on the integrated management platform through the network and other methods, and seamless communication, control, and output between various types are achieved through software communication. Users can realize various functions through only a friendly graphical interface, which reduces the hardware cost and avoids the connection between various types of complicated and messy systems.
4. Video review
In order to effectively avoid the occurrence of false alarms, the situation of the alarm scene can be settled as soon as the incident occurs. Generally, a video review function is adopted. Integrate a camera on the detector, capture the scene picture after the alarm, and realize the alarm video review function. In the future, the alarm system can directly support network cameras and use streaming media to implement alarm video review functions.
5. Stop at the event
Although our security technology has developed for many years and the technology is constantly updated, it cannot reverse the dilemma of passive defense. Even if the cameras and detectors found guilty behavior, they could only watch the suspect wantonly harm financial and physical security, and then he went away, but the system had no way, and the huge security system invested in the huge investment has become Expensive spectators. When Jing Fang arrived at the scene, the suspects had often fled, and they could only retrieve the video of the scene of the crime scene as an investigation clue, which required a lot of manpower and material resources, and the detection rate could not reach 100%, even if the suspect was arrested The corresponding punishment can only be given from a legal perspective, but most of the personal and property losses caused to the owner can no longer be compensated.
To this end, the industry has called for the birth of technical defense products that end criminal behavior. The anti-theft and smoke system is the first. Beijing Funitec Security Technology Co., Ltd. has a solid technical team and deep technical precipitation for such products. The product technology far exceeds Europe and the United States, and leads the technical vane of subdivided products.
