Infrared detection alarm working principle: After installing the detector in the area to be protected (such as the living room, bedroom, kitchen, hallway, warehouse, store, etc.), if the thief enters the prevention area, the detector will detect the human body infrared. And immediately emit a digitally encoded alarm signal, which is received by an infrared alarm installed within one kilometer, immediately emits a harsh alarm sound, scares the thief, reminds the owner, the owner can follow the alarm light on the panel of the infrared alarm , confirm the alarm location, go to catch thieves.The machine also has an automatic memory alarm time function. If the owner is not at home, then when you go home, you can know when the thief is visiting the home.
Infrared detection alarm?is?divided into active and passive. The active infrared detection alarm is an alarm that actively emits infrared rays. When the infrared rays hit an obstacle, they will bounce back and be received by the probe of the alarm. If the probe is detected, the infrared light is still, that is, the red line is continuously emitted and rebounds continuously, then the alarm will not alarm. When a moving object violates this invisible red line, the probe will detect an abnormality and will alarm.
Infrared is a band in the electromagnetic spectrum that is between the microwave band and the visible band. Electromagnetic waves with wavelengths longer than 0.78 μm up to 100 μm belong to the infrared band. Since its wavelength is longer than the red light wavelength in visible light, it is located outside the visible red spectrum, so it is called infrared. Infrared light can also be called infrared light or non-visible light.
Infrared detection alarm use infrared sensors to detect the presence of foreign matter. When an object is found to be moving, the infrared alarm will immediately sound an alarm. Infrared alarms are relatively high-tech products. Many places for storing valuables will be equipped with such infrared alarms. With this kind of infrared alarm, everyone will be more at ease.
