For houses with lots of windows and bigger pets, one of the more ubiquitous sensors is the acoustic glass break sensor. You only need to jam that one for a few seconds to get in.
- vonmoltke 12y agoI have two of those; in fact, my house has all "perimeter" sensors and no motion. What you describe only works if the sensor is non-latching. A latching sensor will trigger the alarm as soon as it reconnects. AFAIK, most glass breaks are capable of latching, though most are not set up to do so. Changing the setting is trivial. Alarm companies have put quite a bit of thought over the decades into anti-tamper measures. I suspect the reason the "hole" described in the article exists is because someone felt the other AT measures would cover it adequately enough for typical usage.
- blueskin_ 12y agoIt's possible to configure most motion sensors to not detect pets by adjusting the height they scan at and/or their sensitivity (most say they won't detect pets under a certain weight). Not to mention that if there is any evidence of a large dog (cats being too small to trigger any decent motion sensor), a "Beware of Dog" sign is just as much a deterrent to break-ins as an active alarm.
