Infrared radiation can get in touch with the outside world in time for accidents, and get assistance. Therefore, it has also been recognized by customers, and it is also a must for some cities as a safety precaution. In the development and production of anti-theft alarm products, infrared radiation is an important and basic component of the anti-theft alarm system. The full name of the infrared radiation is called “beam interception sensor”. The basic structure includes an aiming hole, a beam intensity indicator, a spherical lens, an LED indicator, and the like. This product is widely used in home, school, community, factory, petroleum, chemical and other fields.

The burglar alarm system is a series of more and more attention in the security industry today. He is closely related to people’s safety. Nowadays, with the improvement of people’s living standards, the development of a harmonious city and a safe city is paying more and more attention to the demand for burglar alarm.The equipment of the anti-theft alarm system is generally divided into: front-end detector and alarm controller. The alarm controller is a host (such as a computer host) that is used to process, including wired/wireless signal processing, system fault detection, power supply, signal input, signal output, and built-in dialer. An anti-theft alarm system alarm controller is essential. The front-end detector includes: a magnetic switch, a glass break detector, an infrared detector, an infrared/microwave dual-valve, and an emergency call button.

Taking advantage of the infrared radiation, the combination of superb technology and burglar alarm. The infrared radiation has no blind spots and dead angles, so that the intruders can touch the police without knowing it. Intruders can’t pass the stealth infrared defensive beam network with fast jump, crouching or other actions. When insects or small animals pass through the infrared defensive beam net, they can’t make mistakes because they can’t completely block the infrared defensive beam. Call the police.

The use of infrared radiation product features and its combination with anti-theft alarm products, coupled with the appearance of the design has a unique exterior design, high reliability and external glare protection, and portability, etc., more on the market competitive advantages.

When the object crosses its detection area, the infrared beam is interrupted and an alarm is triggered. The traditional active infrared intrusion detector is often used for outdoor wall alarms because it has only two beams, three beams, and four beam types. Active infrared intrusion detectors should choose the appropriate trigger response time: the response time is too short to cause unnecessary interference, such as flying birds, falling leaves and other false alarms; too long is easy to form a leak alarm. The national standard GB10408.4-2000 active infrared intrusion detector specifies ≥40ms as the alarm triggering time, in view of the application conditions of the traditional active infrared intrusion detector usually installed in the traditional modeling wall. For the installation conditions on the ground, it is necessary to run a high speed of 10m / s to determine the short shading time. If the width of the person is 20 cm, the short interruption time is 20 ms. The alarm is triggered by blocking of ≥20ms. The national standard GB10408.4-2000 active infrared intrusion detector shall not be alarmed if it is ≤20ms.
