Set Up and Connect the ADT Motion Detector

Meet yet another tool in your arsenal to help you stay safe in your home: the ADT Motion Detector. When you use the motion detector, you can sleep better at night knowing you'll be alerted in the event of any strange movements throughout your home. Total protection and peace of mind, too.

Motion Detector

Afraid of things that go bump in the night? Set up your ADT Motion Detector and be alerted of unusual movements throughout your home.

Use the ADT Motion Detector in a high-traffic area where an intruder would be likely to pass within a 30-foot range, such as a living room or hallway.

  1. Take the ADT Motion Detector to the area where you intend to mount it. Make sure you are within 350 feet of the ADT Security Hub.

  2. Use the SmartThings app on your phone to select My Home, and then touch Add a Thing.

  3. Use the SmartThings app to scan the QR code on the front of the detector and then follow the on-screen instructions to complete setup.

    Note: You can also enter the code manually.

  4. Remove the tab on the detector marked Pull This Tab.

  5. Pick a location 6.5 to 7.5 feet above the floor and mount the detector on a flat wall or in a corner.


For best results, make sure:

  • There are no objects blocking the detector’s view and it’s in a stable location.

  • The detector is not aimed at stairs, furniture, or other surfaces where a pet might climb, or used in a room where large pets over 55 pounds may be present and could cause false alarms.

  • The detector is not placed near a source of heat that could cause false alarms, like a heating vent or fireplace.

    Make sure you test the coverage of the detector by pressing the Walk Test button on the side. For the next 10 minutes, the red LED will illuminate when it senses movement, allowing you to adjust the aim of the detector using a screwdriver so it covers the desired protection area.
