The infrared radiation detectors consists of an active infrared transmitter and a passive infrared receiver, which can generate an alarm state when the infrared beam between the transmitter and the receiver is completely blocked or interrupted by a given percentage.

Alarm system universal infrared sensor.

Six advantages of infrared radiation in infrared radiation detectors:

1. The beam in the infrared band is used, and the human vision is invisible. It has a hidden defense method: the intruder can touch the police without knowing it.

2. The traditional active infrared intrusion detector has a low protection surface and is prone to dead zones or dead ends. Multi-beam long-distance infrared curtain wall products do not have blind spots and dead ends.

3. Complete defense ability: the intruder can not quickly jump (can achieve ≥ 20ms trigger alarm products have this function), crouching or other actions through the stealth infrared defense beam network protection range.

4. Good anti-interference characteristics: the use of blocking all infrared pulse coded beam as an alarm trigger condition, when insects, fallen leaves or small animals pass the infrared defensive beam network, because it can not completely block all infrared pulse coded beams, so a false alarm will occur.

5. Strict anti-destructive ability: When the power line or signal line of the infrared receiving end is cut, the alarm signal output circuit will automatically output the wireless alarm signal.

6. Can work all day. Infrared radiation detectors implement the national standard GB10408.4 – 2000 active infrared intrusion detector “4.1.7 detection distance b) outdoor use: the maximum beam distance of the active infrared intrusion detector should be the detection distance specified by the manufacturer 6 times or more” to prevent rain, fog, sputum, strong water vapor, strong sunlight from attenuating the beam, and resisting the gale (especially the side wind) blowing and causing the beam to shift and other adverse weather and meteorological conditions interference.

Infrared radiation detectors are mainly used in buildings such as fences and buildings with relatively long distances. Compared with infrared radiation barriers, they are more resistant to rain, dust and interference, and are mainly used in home security systems. In the villa and in the single house.
