The Domain Awareness System will draw data from 911 calls, previous crime reports, license-plate readers, law-enforcement databases, environmental sensors, and roughly 3,000 closed-circuit cameras. It will rely on the New York City Wireless Network (NYCWiN), a high-speed wireless broadband infrastructure that allows city agencies to rapidly transmit data, and used for everything from emergency response to reading meters.
Mayor Bloomberg argued that the system isn’t an example of Big Brother overstepping the line. “What you’re seeing is what the private sector has used for a long time," he told Gothamist. "If you walk around with a cell phone, the cell phone company knows where you are We’re not your mom and pop’s police department anymore.”"
