An infrared motion detector is a device that is being commonly used in homes and shops these days to provide security. These devices work perfectly in enclosed settings and are relatively cheaper compared to other home security systems. What an infrared sensor basically does is that it measures the radiations released from the environment and any object that passes in front of the detector.
The passive infrared detection sensors (PIDs) are the most common type of infrared motion detectors used. The PID technology is featured in common area detectors, ceiling sensors as well as pet-immune detectors. Infrared point sensor is another popular type of detector. It comes with twin emitters and receivers and is used to detect flammable gases in a location. This type of detectors is more effective in small, enclosed areas where levels of gas may be hazardous.
An infrared detector system will typically feature a magnetic door, motion detectors and window contacts. The use of motion detectors in the package allows for a complete home security system. You can secure the perimeter when people are present in the house and activate the motion detector when leaving the house to ensure that the house is protected at all times.
Infrared sensor alarms are also being increasingly used in shops to inform staff when a customer enters the shop. The emitter transmits a beam to the receiver. If someone breaks this beam by passing in front of it, the alarm will be triggered. It is the infrared detectors featured in automatic doors found in shops that make all this possible. Automatic door detectors are more or less similar to home security detectors and make use of the same technology. Infrared detection technology is also being commonly used in motion detecting lights found in homes to set off an exterior light.
An infrared motion detector is capable of viewing through the glass, which makes it a perfect choice for home security as there is no need to install anything outdoors. Infrared sensors can be incorporated into any standard home security system. The alarm can’t be triggered involuntarily or by domestic pets passing through the range of the beams. The reason for this is that the detectors featuring the latest infrared technology are designed to be “pet-immune”. They will only detect major changes in the detection range and small changes will not trigger the alarm.
