cheap home securityA few years ago, you’d have to spend $1,000 or more on a professionally-installed home security system to protect your home and loved ones from prowlers and burglars. Today, however, a new generation of easy-to-install, reasonably priced home security devices are available to help homeowners beat the burglar.

During the next year one in four homes in the United States will be burglarized. Despite the threat of burglary, nine out of ten residences are not protected by home security systems.

Now that low-cost home security products are available, many homeowners are customizing and installing burglary prevention systems for their own specific needs. For less than $100, for example, a motion sensor can be installed to protect the perimeter of a home. The motion sensor detects the presence of heat in motion. When someone crosses its overlapping detection fields, the motion sensor instantly switches on an outdoor light to create the impression that someone is home, even when they aren’t.

Another interesting home security device also uses a motion sensor, but for a completely different purpose. When someone crosses the motion detection field, a signal is sent to an indoor alarm that begins barking to scare away potential intruders. The “barking dog security alarm system” retails for less than $60.
