I have a motion sensor on front porch that sets off a chime in my upstairs office. I have 3 surveillance cams on front of house (3 in back) with the monitor feed in my upstairs office, so I know who is out there. I have 2 way audio on one camera but as a rule, I do not acknowledge anyone at the door. I have the front door bell disconnected.
All of the louvers are closed across the front of the house. The back of my house faces south, so tons of sun through back windows. My car is always in the garage and windows are tinted so it is impossible to know if anyone is home. I have a sticker on the front door that says:
We only answer the door to people we know.
(That will keep a potential burglar guessing).
I have a killer audio system and blast music all times of day and night. It is mostly on below ground level and office on third floor, both on backside of house. So nobody can hear it outside. (I block my fireplace flue which would otherwise be a “speaker” directly to the outside). Access to back of house by car is impossible, since it is a valley.
I do not have a house landline phone on purpose. If somebody on front porch “calls me”, I can be “anywhere” I choose to tell them. Entering my property at night from back or front will light you up like a prison yard (if you manage to get over the fence, which is unlikely) lol. My friends all know to call before coming over. UPS/FedEx/Postal all know the drill with packages. All windows in back are treated with thermo tint. I can see out, nobody can see in so I can stand in front of windows dressed/naked, whatever.
Oh, I live alone. (except nights when I get “lucky”, lol).
Life is good…
