Street lamps are such an integral piece of our street furniture, it can be easy to forget that they play a role in keeping us safe. There are many ways that street lights could become smarter to keep city dwellers safer. Smart streetlights are increasingly being fitted with motion sensors which turn the lamp on when motion is detected near the pole, conserving energy when nobody is around. This means that rather than turning lights off completely in certain areas, leaving residents vulnerable along dark streets, councils can ensure lights are on only when necessary. Noise detectors can also be fitted to streetlights; when combined with real-time CCTV feeds they can alert local authorities to disturbances and allow them to respond more quickly.
