SR4 – Bike

The SR4 Detection Device is based on radar technology and thus the perfect solution for detecting and counting bicycles. Unlike other methods of counting traffic (tubes, loops and manual counting) our devices can be used for non-intrusive counting to deliver unbiased traffic data.

  • Highly accurate, radar based traffic detection
  • Non-intrusive counting for unbiased results
  • Lightweight casing designed for mobile use
  • User friendly, in-depth Analysing Software
  • Bi-Directional counting
