I would also get to know your neighbors. Who car or truck is who's, where they live and what they do. I technically live in a subdivision with 30 homes or so, so my situation might differ, but knowing my neighbors is part of my home security. The guy across the street is usually home, and if we have a house fire, I've told my young kids to go there first and if a Prius so much as parks in my driveway he tends to ask me about it later.
