Radar Speed Sign

ST-RSS200 is a radar speed sign (driver feedback sign) equipped with 24GHz German Doppler radar, embedded smart microcontroller, high-brightness LED face feedback display screen and the user LCD screen as a programming interface.


It's an effective and affordable traffic-calming device designed to slow speeding drivers down by alerting them of their speed and has been widely used in multiple locations like highway or areas where vehicles come in close proximity to pedestrians such as school zones, construction zones, residential areas, and college campuses. In some applications, they are also used to gather information to see if additional traffic control measures are needed or integrate with enforcement cameras for speeding capture.
