All the wiring will be inside the house, probably run through the attic.
But about locks being complicated, I disagree completely, Check out Bosnian Bills Lock Lab on youtube, this guy has been able to pick through some very "complicated" locks in mere seconds, sometimes only by raking, when they're locks that aren't supposed to be able to be opened by raking.
I see your point, but you've got to see mine. That's Bosnian Bill with a Lockpicking show on the internet, not exactly your ordinary criminal or lock man, that's a celebrity lock picker. Buy a set of picks, It's not that easy.
We had permission to break a schlage with a carpenter's hammer and it took a lot of beating just to damage the lock. And that was a door handle lock. I think we bashed it for 15 minutes, shreded it, but it was still hanging in there jamming the handle hole. Made a ton of noise. You're right, it's easier to kick it. Could have taken the hinges in less than 1 minute, again noise issues.
The whole idea is to slow someone down multiple times and create obstacles and noise, each obstacle is a chance to give up and walk away or be discovered. If someone kicks through your door and you have more doors to kick through, that's a chance to retrieve a weapon, call the police and save your life. In reality, anybody determined can get into anything. Once worked on chaining a wrought iron welded security door to a truck in the front lawn (with permission).
If you had a dog sandwiched between two locking doors leading to the main part of the house, the dog will bark while they're working on that lock and alert you, plus they have to deal with the dog and break the second lock to get into the main house. Lots of time to wake you up and get help, lots of time for them to change their mind and go away.
Those Home Depot new york stop locks are a joke and give women a false sense of security. They fork under the door handle and wedge against the floor. My mother had them, until one day I was in a mood and impatient and shoulder bumped the door destroying the lock like it wasn't there, instead of walking around the house to the free door. It's only value is as a noise maker. Same with hotel door hasps, even so, they're kind of valuable as a noise maker.
I like weird's idea about the battery powered (backup) camera system, pretty solid.
