Design your home to have a central room/hallway full of dummy doors that serve as traps for burglars. If someone tries to open a dummy door, they instantly regret it.
Add a few dummy doors to a strategic place in your home. All the doors should look equally real. None should be the obvious/logical choice.
If the real door is obvious (at the end of a hallway) it might be necessary to rearrange the walls. Move the real door to the right or left and make the obvious choice a dummy door.
The dummy doors obviously lead nowhere. They could be made to open so that the blank wall is revealed. They could also be locked or even glued shut.
The home owners would obviously never open the dummy doors. There could be all kinds of trap mechanisms behind them. Ranging from "home alone" style to professional security solutions. Here are a few ideas:
Eye level pepper spray
Loud alarm that the burglar can't shut off
An automated turret armed with a tranquilizer dart
Flashlights + camera that streams video into the cloud and alerts you or authorities or both
Opening a dummy door causes steel sliding doors to cover/lock all real exits. This would be feasible if the walls were made of concrete/bricks so that the burglar cannot crowbar his way out.
What else could be triggered with dummy doors?
