Burglars are busier than ever these days.

Government statistics show that three out of four American homes will be burglarized one or more times during a 20-year period.Households in urban and suburban areas run the highest risk of break-ins, according to Dynamark Security Centers, with rural homes a close second.

Most burglaries, 53 percent, occur at night, says Dynamark, and law enforcement agencies solve only 14 percent of the crimes annually.
