Infrared Perimeter Protector Alarm System - Wireless Outdoor Security Motion Detector for Home & Business Protection | Ideal for Backyard, Garage & Property Security

This device is a tripline-activated early warning intrusion detector which alerts the observer while the intruder remains unaware that he has activated the alarm signal. Utilizing infrared light technology, its 940nm signal is invisible to the naked eye yet very visible to night vision scopes and low-light cameras.

It produces a unique pulse rate that easily distinguishes it from nearby ambient light sources. The signal can be seen up to one mile away with 3rd generation night vision viewers. Easy to operate and weather-resistant.
