I don’t pay for the home monitoring system, but I do have unlimited cam. I share my camera access with my spouse who has his own login as he also monitors his mothers cameras. He is not able to see anything on the monitoring screen in order to engage disarm/home/away. Since his mom and I are primary on on each of our accounts and we share with him is there not a way he can have access?
No, unfortunately guest accounts are extremely limited, to gain access to features like that you need to share a login.
Yes, in a trusted household you can share the same ID, giving you all the same abilities.
The issue seems to be that that he is guest on two accounts. I think the solution is to share a login for the spouses and have mom share her cams to that account. Spouses have full access to their cams and guest access to mom.
