I bought this device for use in our gazebo. Idea: If there someone breaks, makes the inevitable noise and then I get them on the phone wind of it. That is the theory. In practice, however, the device proves it as much too sensitive. What works effortlessly to Enable / Disable via SMS. Even the preview of a call works perfectly. But the device is "hot", so it reacts at noises around> 45dB. Throws So the neighbor's lawn mower or raging outside a stronger storm, can already take care of the alarm. Impractical when every minute the phone rings and a (mis) will report the alarm. Unfortunately, there is also no way to adjust the sensitivity. The only option: a provisional "soundproofing" build around it, so that the sound is not as strong penetrates the micro. We'll see if it succeeds.
