The speedALERT-SZ from All Traffic Solutions brings together the SPEEDsentry radar speed display and the speedALERT speed-dependent messaging system. The result is a compact, powerful solution that makes light work of informing motorists of their speeds and delivering targeted messages to impact their behavior. The speedALERT-SZ is ideal for school zones, campuses, industrial parks -- any location that requires regular, targeted speed enforcement. Messaging and speed display occur in a unit that measures 30 inches by 40 inches, weighs 48 pounds, and is mounted to a light post, telephone pole or other similar structure. Speed digits are 18 inches high, and the full-matrix messaging display is graphics capable.
