PIR motion detectors
PIR motion detectors are an essential component of any modern security system. These small electronic devices use passive infrared technology to detect changes in the heat signature of a room or outdoor area, indicating the presence of a person or animal. When activated, the detector sends a signal to an alarm system or other device, triggering an alert or action.
Motion detectors are commonly used in home and commercial security systems to monitor entryways, hallways, and other high-traffic areas. They are also popular in outdoor security systems, where they can detect intruders and trigger lights or cameras.
