Your motion detector keeps going off all the time. What can you do? It may seem like you can either shut it off and be completely unprotected, or you can find yourself responding to false alarms all the time. But there are some other solutions you might want to try first, before simply upgrading your tech.

1. First, Adjust Your Detector

Many motion detectors are going off simply because they haven’t been placed properly. You may need to adjust your detector by moving them around a bit. If your detector is in a wide open room, for instance, and is detecting things that are going on in the next room, you may want to angle it down so that its line of sight only encompasses the room. This is useful if there are areas in your home, inside, that you know things are going to be moving in (such as the family pet).


Motion detectors should usually be placed in strategic areas. For instance, hallways. You know that many people are going to try to enter through the front and back doors, so pointing a motion detector directly at these doors can help. On the other hand, you might have your pets in the kitchen.

2. Make Sure Your Detector is Working Properly

When was the last time you’ve changed the battery? Often motion detectors can go off because they have not been maintained or the batteries are dead. If your motion detector is going off for no reason at all, change the battery, clean it out, and then check it again. Your motion detector will likely to continue going off at intervals if it’s poorly powered.

Of course, motion detectors, like anything else, don’t have an infinite lifespan. Eventually a motion detector is going to need to be replaced. If your motion detector is more than five to ten years old, it’s possible that it has simply started to die, depending on how expensive and durable it was when you first purchased it.

3. Secure Everything in Your Home

Your motion detector might not be too sensitive, you might just have more things moving in your home than you think.

In fact, Guardian states that 70% of false alarms are caused by user error adding that open, unlocked, or loose-fitting doors/windows can also lead to false alarms. They’ve seen false alarms caused by everything from balloons to large bugs to rotating holiday decorations that move in front of motion detectors.


Before unplugging that motion detector, make sure you’ve checked:

  • To make sure there aren’t any flies buzzing around, or any cobwebs or spider webs near the detector itself; this can eventually build up and cause false positives.
  • Look for any decor that could be moving around, such as streamers that have been left up from a party, holiday decorations and lights, or house plants with broad leaves.
  • Check any doors and windows for movement during drafts and gusts, and close any doors and shutters properly before leaving the home.
  • Check your drapes, even if your windows aren’t open your drapes could still be moving when your HVAC system kicks on.

What if none of these three steps work? It is possible that your motion detector is simply faulty or old. Prior generations of motion detectors were notorious for false alarms and there was often very little that could be done about it. More advanced systems today can be setup to trigger only when they should. For more information about new motion detector technology, contact the experts at Protect America.
