Avoid false alarms while you're away from home with the Next Digital Wireless Pet Immune Motion Detector. Designed for home owners with dogs, cats and other critters, this PIR (Passive Infrared) Motion Detector lets Gizmo and Sassy roam freely without setting off your home security alarm.

This is cutting-edge technology, built for convenience. With Visonic's True Motion Recognition and Target Specific Imaging optical system, this Powercode motion sensor will only recognize human body movements, understanding and avoiding pets that weigh up to 85 lbs.

With FM Digital Signal Processing, this reliable motion detector is compatible with the PowerMax alarm system as well as all Visonic Powercode wireless panels and receivers. This is the alarm industry's best detection accuracy motion detector. The built-in anti-collision Powercode technology ensures that signals transmitted at the same time are acknowledged by the receiver- so basically, when you add this device to your alarm system, your wires won't get crossed and efficiency is high.

Catered to the pet lover who also yearns for a strong home security system, the Next Motion Detector is one of the most favored additions to Visonic Alarm Systems.
