ADT Outdoor Camera will not stay connected to Wi-Fi

The checks in more detail

An outdoor camera is usually far from the router, behind a wall, so check the signal at its position with a phone, and add an extender or a node nearer if it is weak. Brick, stucco, foil insulation and metal siding block Wi-Fi, so a camera on the other side of such a wall may need the access point moved. After a router or password change the camera must be told the new network, which usually means a reset and a new enrolment. Check that the router broadcasts a band the camera supports, and that the camera is not on a guest network.

Hidden networks and networks that require a web login do not work for cameras. Interference from microwaves, baby monitors and neighbors' networks can drop a 2.4 GHz link, so change the router's channel to 1, 6 or 11. Restart the router and the gateway, router first. Keep the camera's firmware current, which the system does on its own. If the camera works near the router and fails at its position, the cure is the signal. If it fails near the router too, the camera or its configuration is at fault, so reset and enrol again. The installer can also relocate the gateway.

Pulse cameras register with the system's gateway, and an outdoor camera that drops out may be struggling to reach the gateway and not the router at all. Zions Security's guidance for offline ADT cameras puts the gateway at the center: move the gateway nearer the camera if you can, power cycle the camera, and re-enrol it if it still fails. Keep a note of where the gateway sits, because an outdoor camera on the far side of a garage often needs the gateway moved a room closer. Check that the camera's LED is no longer blinking continuously after the move, which is ADT's sign that it has found its connection again.
