Chicago's Mayor Emanuel and Public Building Commission members agreed to expand Chicago's surveillance network.

New cameras will go up around three buildings in the financial district: the Federal Reserve, the Board of Trade and the AT&T switching center, the Chicago Sun-Times reports.

Mayor Emanuel insisted these potential terrorist targets need additional protection, says an msnbc.com report. "They were not a part of the network. The fiber had already been laid," he said. "We should complete it because it's identified as important in the Homeland Security reports. ...The camera network is a part of security and safety for the city," he said.

DHS will pay for the new cameras, which will cost $650,000.
