It wouldn't make sense to have security cameras on the inside of the house, so what will the cameras be replaced with?
probably webcams, or something of the sorts if not actual security cameras.
idk i'm probably wrong here since i don't really follow this series at all since fnaf 2 came out, but i'm just going to go out on a limb here and say the person the animatronics or whatever the hell kind of terminator demons they are now are hunting, is probably not mentally stable
this has more to do with setting up web/security cameras everywhere, but there was some woman who some guys found on those unsecured webcam things. she had like 3-5 webcams positioned around her house and some disturbing stuff set up, and she would just sit around in there most of the time. so it would kind of make sense to have the cameras sitting around everywhere
