When I would set up a home for self defense, I would put motion sensor lights in every room except the master bedroom. I would train my clients to stay in the dark as much as possible. The motion sensors were aimed away from approach from the master bedroom, so moving from MB to unsecured areas would not trip them. Intruders would be tripping them, but habitants would not.
Of course, this was before the days of weapon-mounted searchlights, so I don't have experience with the method of "I see; you are blind" tactics.
Armed and Safe: Not just a theory
If it time to bury them, it is time to dig them up.
