Infrared alarm, infrared alarm can be divided into two categories: active and passive. The active infrared alarm uses the alarm system to send out infrared rays actively. When the infrared ray hits an obstacle, it will bounce back and be received by the probe of the alarm system. If the probe detects that the infrared ray is stationary, it will continuously send out a red line to bounce back, so that the alarm system will not give an alarm. When a moving object touches the invisible red line, the probe will detect an abnormality and give an alarm.
