Don’t forget the sign
The single most important component of our system is the alarm company sign that you post in your front yard. In survey after survey, burglars say they avoid homes with alarms – so just letting a thief know your home is secured (even if it’s not) can prompt them to move on. These are things a burglar won’t tell you.
Alarm systems aren’t the most reliable
That said, alarm systems are actually not very good at catching crooks. One study found that police were more likely to catch burglars in the act at locations that don’t have alarms — because when there’s no alarm, officers are usually responding to the report of an eyewitness, which is far more reliable. Why’s that? Because 80 to 95 percent of all alarms nationwide are false alarms. Many large police departments won’t even respond to your alarm unless it’s verified by sound, video, a private security guard, or an eyewitness. Your city may also fine you for repeat false alarms.
