i will once again beat my drum for defense in depth. Install passive measures to alert you of an intrude at your property perimeter. Harden your doors and windows. Exterior doors should be attached to reinforced frames.
Windows should be protected by landscaping. Holly bushes or some other thorny tough plant. In the desert we use a lot of cactus. I have used black berry bushes.
The windows themselves can be coated with a laminate similar to that used to tint car windows. The laminates will hold the glass in place should a BG attempt to break the window.
Motion detector lights above doors and windows will also deter the BGs. Audible alarms will also help deter the intruder.
these measures will allow you time to respond to the situation. You will not have to move to your position after the BG has kicked in the front door.
