I actually have TWO of these hooked up to my system. One on each corner/entrance to the property. One works fine, the second is constantly on. I researched this online and believe it has an air leak and perceives wind/temperature changes as movement. It is obvious that these detectors have no thermal compensation and are not sealed. I will try to seal it with silicone and then tape the sides of the lens together to minimize false alarms. I don't like the "draft" and wish Orbit used detectors with adjustable sensitivity and better housings.
