Illuminating Concepts makes LED-based streetlights called Intellistreets, which can auto-adjust to the brightness outside to help save power. They also include a Wi-Fi connection and built-in speaker, to stream audio broadcasts to anyone within earshot. Oh, and they also have audio and video recorders. These are supposedly to field calls for assistance; but if you're walking in a city with Intellistreets, like with Las Vegas or Branson, Missouri, how comfortable are you knowing that the lampposts have Wi-Fi transmitters, a camera, and a microphone?
Also included: proximity sensors to record pedestrian and road traffic, and optional video displays to broadcast advertising, Amber Alerts, and other "civic announcements." And yes, this was with paid for with federal funds.
