The owl sensor can be positioned inside or outside to alert an intrusion. 

The owl sensor activates by detecting movement that contains heat. The owl driveway alarm will activate when a person walks through the beam and when a car drives through the beam as it also produces heat.  The detection range set on low sensitivity is 10m  and at high sensitivity 15m.  The angle of the beam is 15°.

Three AAA 1.5V alkaline batteries are required and if the sensor is triggered twenty times a day the live of the batteries will be approximately eight-twelve months (batteries not included).
