DIAGNOSIS The solid red LED indicates the camera failed its boot sequence or cannot authenticate with your account. This is most often caused by corrupted firmware or a failed registration attempt.
FIX Perform a hard reset. Insert a paperclip into the small reset pinhole on the side of the camera. Hold for 30 seconds. Release. The camera LED will flash red, then blue. Delete the camera from your Blink app. Re-add it using the Add Device flow. Ensure you scan the QR code on the back of the camera or the included card.
IF THAT DIDN'T WORK The issue may be account-specific. Log out of the Blink app completely. Uninstall and reinstall the app. Log back in with your primary Amazon account credentials. Attempt to add the camera again.
HEADS UP After a hard reset, the camera will require a fresh firmware update. Keep it within 10 feet of the sync module and powered until the update completes. This can take up to 10 minutes.
