The system, called the Domain Awareness System and unveiled Wednesday, was developed jointly by the NYPD and Microsoft Corp., the New York Daily News reported.
"We're not your mom-and-pop police department anymore," New York Mayor Michael Bloomberg said. "We are in the next century. We are leading the pack."
Police officers will have access to the city's more than 3,000 street cameras and all of the department's databases through the one system, said NYPD Commissioner Raymond Kelly.
"For years, we've been stovepiped as far as databases are concerned," Kelly said. "Now, everything that we have about an incident, an event, an individual comes together on that workbench, so it's one-stop shopping for investigators."
Because the police department played a key role in developing the system, should Microsoft sell it to other cities across the country, the NYPD will get 30 percent of the proceeds, the New York Post reported.
