Radar speed signs provide positive visual enforcement of the designated speed limit. These signs have been proven to be effective, particularly with today’s highly visual, often distracted drivers. Usually installed in areas where speeding vehicles are in close proximity to pedestrians. The Solar Radar speed limit sign utilizes ultra-bright, high quality and long-life LED technology to provide an animated enforcement of the designated speed limit. The minimal current draw of the system is simply and effectively powered using solar energy. A Bluetooth APP (android) allows control over the full dot matrix display area to change the posted speed limit between 00 – 99 Km/h and system analysis. Once the speed is set the radar detects oncoming vehicles and displays the vehicle speed.
