Engraving your property will allow you to trace your valuables, should they be stolen. Computers, tools, jewelry, and other valuables should be given individual identification numbers. If you don't own an engraving tool, contact your local Police Department. Most city level Police Departments allow residents to borrow engravers at will. If you haven't joined a neighborhood watch program, consider it now.
Most communities form some type of program, in which home owners look out for each other.
Basement windows are often overlooked. They may be small, but they're common points of entry for burglars. Lock all basement windows and keep them clean, so you can see out. If basement windows are located at the rear of the house, install additional lighting to the area. Ladders, pieces of wood, bricks, lattices, pipes, and TV antennas are tools to burglars.
