I think he is asking if you have to have the camera's and the phone together during setup, or can someone who is in NM with the phone sign in to see the cameras in Indiana.
I have never used the cell game camera's but I assume you set up some type of profile within an app. He should be able to download the app and you can give him what ever log in information the cameras require and he could see the pics from them, that's purely a guess on my part though.
