Just learned this the hard way. I set the camera up last week and when I got up here on Saturday I unplugged it. Getting ready to leave today and plugged it back in; checked my phone app and it says the camera is not connected.
I don't have my laptop so I tried a Microsoft Surface RT that we leave up here and that will not run the setup software
I guess you are supposed to use the app to turn it off and hope your wife doesn't turn it on
