A dowel or a pin to secure a glass door has been installed to prevent the door from being shoved aside or lifted off the track. The sliding door is locked every night and each time we leave the house. Every window in the house has a working key lock or is securley pinned. Windows are always locked, even when they are opened a few inches for ventilation. There are no dark areas around our house, garage, or yard at night that would hide prowlers.
Every outside door has a bright, working light to illuminate visitors.
Floodlights are used appropriately to ensure effective illumination. Our house number is clearly displayed so police and other emergency vehicles can find the house quickly. At least two light timers have been set to turn the lights on and off in a logical sequence, when we are away from home for an extended time period. A neighbor has been asked to tend the yard and watch our home when we are away. Gate latches, garage doors, and shed doors are locked after every use.
