joanne, that I am not sure of. I think just land, and that is what we have in Alabama, but I have heard they can now use some type cell arrangement. That is one reason we have not put in our TV Villa, yet. Will probably have installed though this Fall.
One of the things I also like is they even monitor your battery conditions in the devises. They will call you and tell you when they see one is low, so you don't even have to worry about that, as they will even change it for you. They pretty much take care of everything.
No permit etc is needed, as everything is inside. They do a great job of installing the devises also. We have the wireless which I highly recommend.
