Interlogix Indoor Wireless PIR Motion Sensor, Pet Immune
The Interlogix DS924i protects your home or business by sensing moving objects indoors. Position the sensor away from heat sources and windows, looking in to the area it should protect. Using passive infrared (PIR) technology it will pick up moving objects across its path. In homes with pets, it is rated up to 40 lbs pet immune. We recommend using it in rooms that pets will not frequent to ensure false alarm reduction.
