Solar-powered Driveway Alert
Solar-powered driveway alert eliminates worry about dead batteries
This weatherproof, wireless sensor system detects vehicles pulling
into your driveway to alert you of visitors before they come to the
door. Completely solar-powered sensors mount in line of sight of one
another, which creates a dual-beam barrier. Requires a positive break
of both beams to activate an alert – no false triggers due to wind, sun or small animals. 50-ft. range from sensor to sensor; 1,000-ft. range from sensor to indoor receiver. Indoor receiver features four unique tones and accommodates up to 32 pairs of sensors for use on multiple driveways or entrances. Imported.
