Product Description

Targetted at speed enforcement and vehicle counting applications, Geolux RSS-2-300 T is a Doppler radar speed sensor operating in K-band, enhanced with advanced phyTrack vehicle detection and tracking algorithm. Designed for traffic applications, RSS-2-300 T radar sensor reports a list of all currently detected vehicles up to 20 times per second over serial or CAN interface. RSS-2-300 T sensor supports ASCII-S and GLX-NMEA serial interface data protocols, and support for more protocols can be added on customer request.

Field-proven Geolux RSS-2-300 T radar sensor is certified according to both European and American standards, which makes it an ideal solution for our partners that operate globally. Advanced phyTrack vehicle detection and tracking algorithm analyses detected vehicle speeds in real time, and extracts precise target statistics data such as total vehicle count, average speed and road utilisation.

Radar Configurator Software

Geolux provides a user-friendly RSS-2-300 Configurator PC software free of charge. The software connects to the RSS-2-300T radar over serial port and can be used to configure radar operating parameters. Additionally, the Configurator utility displays all currently detected targets, and detected target statistics.

RSS-2-300T stores all detected vehicles’ information to internal memory storage. The capacity of internal memory allows storing data about at least 500,000 detected vehicles. The stored statistics data can be accessed by connecting the RSS-2-300 to the PC using serial cable connection. Geolux RSS-2-300 Configurator PC software downloads the traffic data to the PC and allows its users to export the data to CSV format for further analysis. Geolux RSS-2-300 Configurator also displays traffic statistics information, such as total vehicle count, percentage of speed limit violations, average speed, 85th percentile, 10 km/h pace, speed histogram, time of day histogram, speed limit compliance by hour histogram and speed limit compliance graph.

RSS-2-300 Configurator runs on Windows XP or later, both 32-bit and 64-bit.
