2. Passive Detection – Passive Infrared (PIR) technology continuously monitors movement within 25 feet of the sensor for any intrusions
3. Adjustable Alarm – Choose high volume alarm or low volume alarm and flash LED warning light. Notice privately when sensors notice guests arriving at your property or raise the volume to warn intruders to leave
4. Avoid false alarms – do not place the detector in an area where wind will activate the detector and try to keep the detector in a clear path to the receiver for best performance
5. Long-lasting power – alarm base: 3 “C” size 1.5V batteries or 6V DC power adapter (not included in supply); motion sensor: 1 9V battery each (not included) (for best performance , please use fresh, high-quality alkaline batteries.)
