In IR (InfraRed) detector is a circuit that receives an infrared input, either in an alarm or as a heat sensing device. In an alarm circuit, using an infrared beam rather than a laser has both advantages and disadvantages. Passive heat sensors rely on a general increase in temperature to identify a likely source, e.g. an animal, person, or vehicle engine.
