3 ZOOM ZOOM: In the movies, thieves outsmart surveillance cameras by “timing the cameras” and acting when they are focused in a different direction.

4 KICKING THE HABIT: More than half of all burglaries occur when thieves kick in doors. The Door Jamb Armor reinforces weak points by adding a jamb shield, which makes it almost impossible for a door to be kicked in. The new Low Profile Door Shield is about 60 percent smaller than a traditional shield. For more information, call 888-582-2294 or visit www.djarmor.com.
