Why False Alarms Happen at Your Home—and How to Prevent Them

April 8, 2025

'}}

False alarms are an all-too-common issue for homeowners with monitored alarm systems. And when they go off, they can be disruptive, costly and cause unnecessary stress—especially if you’re not home when the alarm sounds. Some local police departments may even charge you repeat fees for false dispatches. For Northern Virginia homeowners who travel frequently or live part-time elsewhere, a Home Watch service is invaluable to check on your property when an alarm is triggered. In this post, we’ll look at why false alarms happen at your home and how to prevent them.

What Causes a False Alarm?

There are several reasons why your alarm system might trigger when there’s no real threat:

  • Faulty or Aging Sensors. Over time, motion detectors and contact sensors can become less reliable. A loose wire, corroded contact or worn battery can create false signals.
  • Bad Weather. Flooding, strong winds and heavy rain can affect outdoor sensors. Wind might rattle an unlocked window or blow debris in front of a motion sensor. Sudden downpours might cause a malfunction in older water detection systems.
  • Environmental Changes. Shadows moving across a room, headlights flashing through a window or a reflection from a passing car can trick motion detectors or cameras. This is especially common with systems that are overly sensitive or poorly positioned.
  • Animals or Insects. Insects crawling across a motion detector or small animals moving in the yard can trigger an alert. Spiders nesting near sensors is a surprisingly common issue.
  • User Error. You might forget to disarm the system, leave a door ajar or have a guest enter the home without the cost.

Other contributors that can trigger a false alarm include high humidity, chemical smells, improper insulation, dust and dirt.

Smart Solutions to Reduce False Alarms at Your Home

Reducing false alarms starts with a well-designed, layered security system.

  • Use Redundant Sensors. A system that includes both perimeter sensors (on doors and windows) and interior motion detectors is less likely to raise a false alarm. One sensor verifying the other adds a layer of confidence before the system alerts you.
  • Add Cameras. Security cameras—especially those with motion-activated recording—can help you or your monitoring service confirm whether an alert needs a response. Many systems allow for remote viewing in real time.
  • Incorporate Smart Home Technology: Newer systems use smart sensors that adjust based on ambient conditions like time of day, light levels and weather. They can distinguish between actual intrusions and normal environmental changes.
  • Do Routine Maintenance. Clean, test and replace sensors and batteries as needed.
  • Use a Home Watch Company. Your Home Watch company can include regular system checks as part of your service plan.
