> The Detroit Police Department no longer responds routinely to house alarms, because 98% of house alarms are false. Detroit Police officers will respond ONLY to house alarms that can be VERIFIED as not being false alarms ... DPD recognizes four different ways that an alarm can be automatically verified ... An alarm system sends one signal from a door, window, or other perimeter/exterior sensor AND sends one signal from some sensor inside a house. An alarm system sends three signals from one or more interior sensors. An alarm system sends an audio signal that lets a company monitor hear an intruder. An alarm system sends a visual signal that lets a company monitor see an intruder.
I think organized criminals would call off an operation if circumstances they haven’t predicted occur. Especially those that significantly increase the time or reduce the chances the operation will be successful.
One thing is having the inside doors lock. Another is encountering an armed individual. Finding non-portable hard to open safes, etc.
But then again, it’s mostly better to diversify where you keep your belongings so you don’t end up a victim of organized crime in the first place.

What deters non-small (organized?) burglars?
