Such a benign and banal part of the urban landscape that city-dwellers may not even notice them, street lights are useful for brightening up a road and not much else – or so you might think. People these days are used to the idea of CCTV cameras, even hidden ones, but street lights tend to blend in to the background. Perhaps that is why they are finding new functions in the modern world, with its zealotry for surveillance. These seemingly innocuous devices can host anything from microphones and cameras to facial recognition and de facto compulsory 5Gwifi transmission.

LED lampposts are being installed in cities and public places across the world, only partly because of their economical, energy-saving properties. With the new installations comes a wide range of sensors designed to capture data on public activity. As Chuck Campagna, CEO of lighting company Amerlux, told The New York Times, “We are opening up an entirely new area in lighting applications and services, including video-based security and public safety, parking management, predictive maintenance and more.”
