One thing I do when setting up a domicile for interior defense is install motion sensors on a light in every room but the bedroom(s) This puts the BG(s) in the light and the GG(s) in the dark, which is one of the few times it is good to be in the dark.
There are drawbacks to this, granted, in that you will be lit in each area, should you decide/need to clear the house by yourself. However, Gathering in the saferoom and waiting for the police to clear for you is still the safest way. Not as exciting, perhaps, but certainly wisest.
