I use cameras, lights and pray.
Located with a fairway on one side and woods on another it's a lot of dark space around. Inside I have guns and an alarm with lots of motion, glass break and door sensors, and a small dog that barks and everyting.
Bad guys are getting bolder not smarter, just pay attention and pray nobody gets in your door, window, chimney cause if they do you are on your heels trying to take your ground back. Burgulars don't burgul alone 2 or more can carry more stuff so you may have to fight off more than 1, not something I have to think about dealing with while my family is in panic mode.
