Description

The Harper Chalice VibreWire detection cable is installed in cable protection ramps (speed humps) to detect vehicles entering a pedestrianised or restricted access area.

Vibewire Signal Analyser
The SA2000 analyser processes audible signals and vibrations detected by the Vibewire detection cable generated when a vehicle passes over the speed hump. The system sensitivity is set up to allow detection of vehicles at speeds in excess of 10mph but not detecting pedestrians crossing the same strips.
