ADT Doorbell Camera shared users or family members cannot control it

The checks in more detail

If the option to add users is missing, you are probably not the primary holder, so ask them to add the person. A mistyped address or an expired invitation stops it arriving, so send a new one and check the spam folder. Permissions decide what they see. A user without video permission cannot open the doorbell camera, and a user with limited rights may see only status. Ask the primary holder to check the user's permissions. Notifications are set per person: each user chooses which alerts to receive in the app, such as doorbell presses and motion, and must allow notifications in the phone's settings.

A person who receives nothing may have turned alerts off, or may have signed in with the wrong account. Live view needs the doorbell to be online and the phone to have a good connection, so test the doorbell on the primary holder's phone first. Some features depend on the ADT plan: recorded clips and the length of history are tied to the service level, so a user cannot see clips that the plan does not record. For a visitor who needs only temporary access, a PIN for the panel is simpler than an account. Never share the primary login; use additional users, which can be removed.

If the invitation fails repeatedly, remove the user and add again, update the app and contact ADT support with the account details, avoiding posting invitations publicly. For a visiting relative who stays a few days, a time-limited arrangement is safer than a permanent account: add them as a user for the visit and remove them afterwards, and write the removal in your calendar so that it is not forgotten. If the doorbell is set up to alert only the primary holder, think about who should receive the alerts when you are away, and add a second person for that purpose, since an alert that nobody sees does no good.
