Strategically placed, motion activated floodlights can illuminate the driveway, entryways and other walkways around your home. Some insurance companies will even offer premium incentives for homeowners with this type of security lighting.

The basic mechanics of the motion detection sensor is fairly simple. The active sensor works by pulsing a stream of energy such as microwaves or sound that is sensitive to changes in the environment. Most lighting systems are of the passive variety designed to detect infrared energy. These passive systems known as passive infrared detectors can be calibrated to detect a person by picking up on the infrared energy they emit.

The motion sensor is sensitive to both motion and the amount of infrared energy that it is sensing. The electronics are designed to win a relatively fleet change in the amount of infrared energy it is sensing. This is why these sensing devices are triggered by a person or animal entertaining and not the boring unhurried change that occurs in the infrared energy in the nighttime environment.
