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 was a little leary, but this item turned out to be great! I like the sensor switch in the back, had to put one of them on low (our hot water heater was setting it off) but once i set it on low I didnt have a problem at all... wide range for motion detectiond, and picks up motion up to 50 ft away! (so be sure to aim it carefully) took a few tries to get the aim right, but once I got it, it worked fabulous!
