SRM radar sensor

Designed to detect vehicles, the high-tech SRM radar uses the Doppler-Fizeau effect principle at a frequency of 24.125 GHz, combined with a high-performance micro-controller.

With this very high frequency and extreme miniaturisation, the SRM radar delivers exceptional performance in a water resistant and compact housing.

Its attachment system, which is specifically designed for street lighting, makes it easy to install and offers the radar multi-axial orientation.

The SRM radar is to be used with the VIA relay to interface with the SensyCity environment.

The radar can operate over a distance up to 150 metres and offers two sorts of information:

  • relay 1 takes all vehicles into consideration (from the adjustable lower threshold, 2 or 4 km/h, up to the maximum detectable speed, i.e. 160 km/h).
  • relay 2 simultaneously senses all vehicles with a speed exceeding the “over-speed” threshold (adjustable from 30 to 100 km/h).
