“The wireless, LED lighting, computer-operated lights are not only capable of illuminating streets, they can also play music, interact with pedestrians and are equipped with video screens, which can display police alerts, weather alerts and traffic information. The high tech lights can also stream live video of activity in the surrounding area. But there’s one major concern.

The lights are being touted as security devices that can assist with ‘Homeland Security’ measures by providing applications like video surveillance and motion sensors.”
