How Do Motion Detectors Work?

It is common for home and office security set ups to include motion sensors to detect any unexpected movement or changes in infrared energy. Once a motion sensor has been triggered by an unauthorised figure, the detector will communicate with the alarm system to notify appropriate response services of a possible intruder. It’s true that motion detectors play a key role in an effective security system, but how do motion detectors work? Keep reading to find out.

 

Passive Infrared Motion Detectors
Passive Infra-Red (PIR) technology enables sensors to detect movements within the confines of a specific area. Through the recognition of changes in infrared energy, PIR detectors have the ability to sense heat levels from humans and animals. PIR sensors are set up to ignore slight changes in infrared energy to account for energy changes due to natural temperature fluctuations, and changes with your space’s natural lighting. If the PIR detects that there is an immediate change to the level of infrared energy within the confines of the space being monitored, an alert is sent to trigger the alarm system.

 

Dual-Tech Motion Sensors
Dual-tech motion technologies offer a solution in which combines PIR and microwave sensors. In combining the two types of sensors, your security set up will be enhanced, decreasing any chances of false alarms. Your security system will only be notified of a possible intrusion, only if both sensors detect an unknown occupancy.
