Here are a few possible reasons why a motion detector may cause an unwanted alarm at your business:
1. You recently installed new displays, balloons, or advertisements.
If you have displays hanging from the ceiling, they may spin when the air conditioning is on. This can cause the motion to trip when your system is armed.
Make sure your displays are not blocking the motion detector. This could prevent you from arming your system, or cause the device to not work properly in the event of an actual alarm.
2. Pests are triggering your motion detector.
Insects may walk across your motion detector, nest inside of it, or build a cobweb in front of it.
Rodents crossing in front of the device or chewing on wires may also cause false alarms.
