>>510484494 (OP)Preparation means just that.
You don't put locks on your doors and deadbolts, even bars on your windows and then leave a bunch of saws, crowbars, ladders and axes in an unlocked outside shed...
But, people do.
Have decent lighting on motion sensors - have cameras hard-wired (no wifi) to a screen and hard drive that overwrites itself every 24 hours.
Solid core doors, and sorry but fuck deadbolts.
Get picrel - they are called barricade brackets
I have something similar
Bar slides in from the side. Strike a balance between weight and strength and practicality. I used a 2x4 made of quarter sawn white oak reinforced with rebar
Sink the lag bolts into the wall studs well on either side of the door and jamb
Even if they use a chainsaw, they can't get through
You can put decorative bars or an iron grate on your windows - do not forget the 2nd floor if you have one. They can and will get up there if they have to.
You can put security doors inside the house as well, like the South Africans do.
No hedges or areas where they can conceal themselves - if you have to have plants, plant something like acacia bushes - even fully grown male African Lions won't fuck with that nasty shit
Plant them under your windows for maximum fuck you
Given enough time, they are going to get in - all they have is time
The goal is to make your place look so uninviting they fuck off to somewhere else and an easier target
Harsh world, but it's just the way things are
