The bad boys of Detroit, the Police Department (not Isiah Thomas, Vinnie Johnson, Bill Laimbeer, Joe Dumars, etc.), was putting in a lot of man power and money behind answering false burglar alarms. They have decided not to put as many resources behind burglar alarm responses any more.
According to Detroit Police Chief Ralph Godbee, 98% of all of the alarms that they handle end up being false. On August 22nd, the police department is going to start requiring alarm companies to verify alarms before responding.
The city of Detroit is not the first company to stop responding to burglar alarms without verification. Thirty other cities in the U.S. and Canada adopted this policy since 1991.
To verify that a crime is taking place, call the police. If an alarm goes off and someone lives in a gated community with security guards, then it becomes the responsibility of the building management to check on the alarms. Video surveillance is another way for burglar alarm companies to monitor whether a crime is actually taking place.
