Add this passive infrared (PIR) motion sensor wherever you want to know if a person enters. The sensor uses "Double Twin Optics" technology - both optical and heat detectors - for extra resistance to false alarms and heightened sensitivity. Built with surface mount devices (SMD) for improved reliability and resistance to electromagnetic and RF interference. Three LEDs indicate status of the sensor: blinking for 2 minutes at startup. upper and lower sensor bank activation, and alarm. The vertical angle of detection can be adjusted internally, rather than mounting the entire sensor at an angle away from the wall. A tamper switch is built in to instantly trigger an alarm if anyone removes the front cover. Operates on 12 volts DC from a power adapter, sold separately.
