One of the best ways to ensure that a burglar does not target your house for a break in is to make your entire block a highly secure area. This involves working with your neighbors so that everyone watches out for each other. Think of your block as a mini community, and you can rely on your neighbors to keep you safe just as much as they can rely on you.
Meet the people who live nearby, and get to know their names, what cars they have and exchange phone numbers. Keep a list of this contact information near a phone, so you can call anyone on your block should the need arise. Consider starting an official Neighborhood Watch Group and working with local law enforcement agencies to help watch over everyone in your neighborhood.
