About Sierzega
Sierzega Elektronik GmbH is an Austrian manufacturer of electronics for road safety based in Thening, Upper Austria. The company develops and manufactures radar speed displays (GR36 and GR48 series, Speedpacer and matrix displays), radar-based traffic counters (including SR4 and SR7) as well as bicycle counting devices. All components are populated and assembled in the company's own production facility in Thening; the electronics manufacturing includes SMD assembly and soldering of components, with modern production machines checking position, alignment and solder joints. In addition, Sierzega develops its own software solutions such as BT-Comm, STerminal, GRS, SRA, SRA Web, GR.net and the SAI platform for remote configuration, data transmission and traffic data analysis. The devices are equipped with integrated data recording, Bluetooth and cloud connectivity as well as solar or battery power. More than 35,000 devices are installed worldwide, with customers and sales partners in over 50 countries. Germany is served by a sales office in Bottrop.
