Apart from the security system (which covers every door and window), I have deadbolts on the front and back door with a 1" drop. The backdoor is a double cylinder since the lock is near the window. All ground level windows have security laminates installed as well as glass breakage sensors. All sliding windows have two breaker bars installed. I have an extra heavy duty chain on the front door and the screen door is heavy duty welded with security weave and a deadbolt. I'm installing motion sensor exterior lights on the sides of the house to compliment the ones I have in the fore and aft.
After they get throught that, they get to meet Mr. Mossy 500 and his 00 Buck pals. ;-)
