Install outdoor security lights in shadowed areas, on garages and around house entrances to ensure good coverage. Position lights to illuminate darker areas around bushes and trees, and choose sodium or mercury vapor lighting. Bright incandescent light is less energy efficient and creates shadows for potential hiding places.
Motion detector lights are easy to install and save energy by turning on only when movement is detected by the sensor. Place these over doorways and garages for best security. Mount motion lights approximately 6 to 10 feet above the ground for optimal sensitivity. Homes in locations of heavy winds and passing animals can purchase a sensitivity adjuster to control the lighting.
