There’s always a chance of a false alarm, either due to sensor malfunction or accidental alarm triggering. False alarms can waste precious resources for emergency responders—when responders have to check in on a false alarm, they’re not available to handle real emergencies.

In order to reduce instances of unnecessary dispatch of responders, many security companies use audio and video technology to verify if a break-in is in progress or if it was a false alarm. This ensures responders have the most accurate information.

There are also a few things you can do to reduce the chance of a false alarm. Keep your system well-maintained, replace any batteries or sensors that are malfunctioning, and make sure everyone in your household knows how to activate and deactivate the alarm and access the control panel. Keep motion detectors away from windows and air vents. Use a strong adhesive and sealant when installing door and window sensors.
