A wired PIR (Passive Infrared) motion sensor is a security device designed to detect motion within a defined area by sensing changes in infrared radiation, typically emitted by humans or animals. These sensors work by detecting the heat signatures of moving objects, which are then translated into electrical signals. The wired aspect of the sensor means it is physically connected to a central alarm or security system via wiring, ensuring a stable and continuous connection. Wired PIR motion sensors are commonly used in home and commercial security systems to monitor entrances, hallways, or large open spaces. When motion is detected, the sensor triggers an alert or alarm to notify the user or activate other security devices like cameras or lights. The reliability and low maintenance of wired sensors make them a popular choice for static installations where wiring is feasible. They are often highly accurate, minimizing false alarms, and are ideal for environments where ongoing security surveillance is essential.
