The full name of the infrared radiation is "active infrared intrusion detectors". Its basic structure includes the transmitting end, the receiving end, the beam intensity indicator, and the optical lens. The detection principle is to use the infrared rays emitted by the infrared light emitting diodes, and then perform focusing processing through the optical lens, so that the light is transmitted to a long distance, and the last light is received by the phototransistor at the receiving end. When an object obstructs the infrared radiation emitted from the transmitting end, an alarm will be issued because the receiving end cannot receive the infrared rays. Infrared is a kind of invisible light, and it will spread. After it is projected, a cone beam will be formed in the initial path. With the increase of the emission distance, the ideal intensity and the transmission distance will be inversely squared. When the object passes over its detection area, it interrupts the infrared beam and triggers an alarm. Traditional active infrared intrusion detectors, because they only have two beams, three beams, and four beams, are often used for outdoor wall alarms.
