I know very little about weaponry, plan on receiving handgun training early next year. But my first thought is so basic, you may have already considered it. Why not have cameras or monitor systems for corridors, entrances and main areas of the house such as bedrooms, living rooms and the surrounding perimeters of your home? There could be a monitor panel in your bedroom and elsewhere on a different storey
We could wire the entire house but, to my thinking, I’m late if I have to turn on a monitor, much less go to where that monitor is.
We do employ a monitor system that is backed up and redundant but, it’s not for a break in.
It is for monitoring while away and storing on site, as well offsite.
