I know people like to imagine of all the orwellian possibilities, but it could have some useful medical cases too. It would be great to put some kind of camera in my grandparent's home to automatically monitor their health. My grandfather fell in the middle of the night, passed out, and was not discovered until the next day. He was still alive, but injured, but it could have been serious.
