A network using existing streetlights is described. Each street light becomes a node in the network, and each includes a power terminal for receiving electrical power, a light source coupled to the power terminal, a processor coupled to the power terminal, a network interface coupled between the processor and the network of lighting systems, and a sensor coupled to the processor for detecting a condition at the node, and in response providing information about that condition to the processor. |
