motion detectors
Automated presence sensors
Motion detectors are devices that sense movement in a space, typically using infrared, ultrasonic, or microwave technology.
They trigger responses—lights switching on, alarms sounding, security cameras recording.
The motion detector lit up the driveway when we pulled in.
Common in home security systems and automatic lighting.
