In home security, IR sensors are commonly used for motion detection and cameras. Since IR technology is safe, reliable, and inexpensive, devices that use IR detection are known for also being safe, reliable, and inexpensive. Some companies may try to replace IR technology with more expensive detection technology, such as microwave sensors.
An infrared detector is a detector that reacts to infrared (IR) radiation. The two main types of detectors are thermal and photonic (photodetectors). The thermal effects of the incident IR radiation can be followed through many temperature dependent phenomena. Bolometers and microbolometers are based on changes in resistance. Thermocouples and thermopiles use the thermoelectric effect. Golay ...
