Great for home protection and safety,
Verified Purchase(What's this?)
This review is from: Skylink HA-434TL Wireless Long Range Household Alert & Alarm Home Garage Driveway Business Office Security Protection Indoor Outdoor Infrared Motion Detector Sensor Accessory (Tools & Home Improvement)
I bought with a bit of trepidation. A few reviews warned of losing settings after power outage. Not so! I followed the instructions and it works great. One on each side of the house, in two zones, even alerts which zones with lights and different beeps. It has four zones to use if you need them. The low price is a plus.
