ADT Outdoor Camera is offline or unavailable

The checks in more detail

If it does not recover, power cycle it by unplugging the adapter for ten seconds, restart the router and then the gateway, giving the gateway about five minutes to come back, and check again. Move the gateway closer to the camera if you can. If these steps fail, reset the camera and enrol it again, and delete the old camera entry first. SafeWise's guide adds that removing and re-adding the camera in the system often restores the connection. Some causes are external: a power cut, an internet outage or a router that has changed its Wi-Fi settings will take every device offline, so check whether other devices are online.

A camera that goes offline at a fixed hour may be affected by a router that restarts or by interference. A camera behind a metal door or a new fence has a weaker signal. After heavy rain, check the outdoor outlet's GFCI. If the camera is online in the account but the app says offline, refresh or restart the app. Check that your internet plan and the monitoring service are active, since a lapsed service stops cameras showing. Keep a note of the times the camera goes offline, which helps the installer. If the camera is offline for days and no step helps, the camera may be faulty, and the installer should test it.

ADT installers record each camera's serial number and the zone it was enrolled under, so when an outdoor camera has been offline for days, the quickest route to a lasting fix may be to ring the company that monitors your system and ask them to check the camera's status from their side. They can see whether the camera last reported to the gateway, how long ago, and whether the account shows a fault, which turns guessing into a short list. Have the camera's model and serial number from its label ready, and the date it first went offline.
