Heads up -- if you use ADT monitoring services through your landline, if your landline is cut or goes down they are no longer able to monitor it. Use wireless / cell phone towers when you sign up!! I learned this the hardway, after a storm cut out our landline I thought I was still secure but I wasn't and lost a lot of belongings. I suppose it's time to upgrade from landlines anyways by now but I was still paying a cheaper monthly fee for it so I hadn't upgraded.
