Take, for example, the distance of your home from the street. Sure, privacy is great, but should anything happen to your home while you're away, your neighbors aren't likely to know about it unless one of them has a key. A home that remains dark night after night sends the clear message that nobody's home. All of these things create stepping stones for potential burglars, who simply climb them, break a window, and enter your home in no time. Check the locks on your windows and doors.
Skilled intruders know that latches are easily broken.
Take a look at your garage door. If so, get them frosted to prevent a burglar from doing his own inventory of your belongings. Also make sure the door is secure and that it can't be shoved open. If you have a basement with exterior double doors, make sure they're made of heavy-duty steel. Wooden doors may be cut open, giving burglars free reign of your home.
