I am the Queen of security cameras. They are all outside, but they sure are nice in my neighborhood. I don't know if I'd like one in the house, unless it was to keep track of a pet or a child, or a nanny/babysitter.
If you are thinking of buying one for home use (inside or out) don't buy one of those that you have to pay a monthly fee, unless you want 24/7 monitoring. Way too expensive and they come with 'contracts' that lock you into a year or more (just like some cell phones).
Good luck.
