Don’t set Your Motion Detector Off By Mistake!

PIR Motion DetectorOur motion detectors are really sensitive – which is a good thing. It assures you that your home is always protected. But if you are new to the system, it can be easy to trigger a false alarm. To help you avoid this, you should understand how a motion detector works. It uses passive infrared technology, which means you not only have to avoid movement while the sensor is armed  but light and temperature shifts as well.

  1. Pet immunity  The motion detector comes with pet immunity; however depending upon the size of your pet, you can increase or decrease the sensor’s sensitivity (to 33 or 55 pounds) Also make sure that when we mount the sensor, it is located so that pets can’t come within 6 feet of it by climbing on the furniture or other objects. (This makes a home with cats not a very good candidate for a motion detector)
  2. Bugs and insects The sensor has built in protection to prevent bugs from getting into the sensor and causing false alarms. This doesn’t stop a bug from crawling across the face of the sensor though and this can trigger an alarm.
  3. Reflected light Infrared energy can be reflected off any glossy surface such as mirrors, windows or floors with a glossy finish
  4. Windows Windows not only reflect infrared energy but they can also allow sunlight or light from cars to pass through the sensor
  5. HVAC Heating and air conditioning ducts should not be blowing air onto the sensor. The detector can’t see the air but it notes the change in temperature and this can cause a false alarm.
  6. Moving objects Anything that can sway or move because of an air current. Things like curtains, blinds, balloons, loose paper or other items that might be blown around by the heating and air conditioning ducts are an issue.
  7. Vibration Make sure that the sensor is mounted on a solid surface and does not vibrate. Vibration may not only cause the sensor to move a little but it can also cause the fields of view in the room to move triggering a false alarm.

These are the reasons why we will not install a motion detector in a garage!
