(NewsUSA) - Most people believe that their homes are secure, but the statistics suggest that many homes are not. In 2008, over 2 million homes were burglarized, resulting in nearly $4.6 billion in total losses. The average burglary victim lost about $2,097 in property.

Burglars, for the most part, like easy targets. The good news? Criminals do not want to be seen, so a well-lit home and yard could deter would-be burglars. Motion detector lights illuminate yards and driveways without wasting energy, because they don't turn on until they sense movement.

Some motion sensors can protect your home with improved reliability, more dependable area coverage and stable performance.

Passive Infrared technology (PIR) technology detects heat from moving objects and also side-to-side movement. Doppler radar technology reacts to actual motion -- not heat changes. Plus, it detects movement toward and away from the home -- straight-on coverage.

For the past two decades, motion sensor lighting has relied on PIR, which detects heat from moving objects, such as people, animals, and cars. Unfortunately, these sensors can be triggered by changes in the wind and temperature, as well as stray objects like branches or leaves. A well-bundled burglar, for example, approaching a traditional motion sensor or product might not be detected on a cold night.
