Ive always been paranoid of home invasion kick your door in type incidents. I keep the steel door bars at every outside door in the house. It wedges under the doorknob to the floor. I figured the average door being kicked in would open first kick. The bar will at least change that to 2 or 3 kicks and give me the extra 4 seconds to grab my weapon and point it at the door. They are less than 20 buxs a piece. 2 seconds could be all it takes. Doors with windows also make me paranoid. I know that most modern houses have a back door with full windows. But the motion activated flood lights are great. Get the really bright floodlights that blind the person
. ANyways, theres my 2 cents worth. Stay safe
