There have been questions about how the average speed cameras at Charleston work including whether they are live and operational. I asked the AWPR managing agent and today I was told the average speed cameras operate using infrared illumination with no requirement for external visible light sources. This ensures that the system can provide a 24/7 monitoring capability without any distracting illumination during the hours of darkness.

The high-powered tower lights nearby are being utilised to illuminate the on-going works, providing visibility for operatives, as construction works progress.
