What is a Beam Sensor?
A beam sensor works when the emitter sends out a beam of light (most often a pulsed infrared, visible red, or laser) that diffuses in all directions, filling a detection area. The target then enters the area and deflects part of the beam back to the receiver.
If anything is detected it will signal an alarm.
