Intrusion alarms offer crime prevention and emergency notification in the event of a break in, but they are also a source of nuisance alarms. Have nuisance alarms caused police officers to become complacent? Years ago, I was a police officer in a major metropolitan city. My district alone (1 of 12) received over 40 alarms in an 8 hour shift, every day. Triple that number if a thunderstorm came through the city. Not one officer ran emergency traffic to an intrusion alarm, unless there was a call from the homeowner in despair, a 911 hang-up, or some other verification confirmed the need. Alarm calls would sit in queue for at least 15 minutes and then officers had 45 minutes to arrive onsite.
