Most burglars don't break glass when people are home and usually won't choose the front door. A single cylinder deadbolt is best when there is no glass near the doorknob. The deadbolt should have at least a one inch throw bolt that goes into the frame of the door, any shorter and the thief could push the frame away from the lock. All deadbolts should be case hardened steel and make sure your door and frame is sturdy, adds Burke. A sliding glass door is the most vulnerable and can easily be lifted off the track.
Windows are also vulnerable.
Burke suggests carefully drilling holes in the window frame at an angle and inserting roofing nails in those holes so people can't open the windows past a certain point. This still allows homeowners to open the window at will, but keeps burglars at bay. A fence will also help keep intruders out. This is a psychological barrier rather than a physical one, since it eliminates what the thief sees as a clear route. Criminals also do not like to be seen, so motion detector lights are also recommended.
