Troubleshooting

Issues scanning the QR code

Make sure your mobile device operating system (OS) is up to date.
Make sure the camera lens on your mobile device is clean and free of debris.
Make sure the QR code on Glass Break Sensor is not damaged, dirty, or covered in debris. Wipe it with a damp cloth or paper towel if needed.
Make sure there is proper lighting in the room. If the room is dark, turn up the lights or move to a more well-lit area.
If the in-app QR scan continues to fail, use your mobile device's native camera to scan the QR code. This will open the Ring app with the QR code already scanned.
If these steps do not resolve the issue, contact Ring Customer Support.
