The city will use $US53 million from a cable company settlement to fund the Homeland Security Grid system, which will consist of 621 kilometres of fibre-optic cable to link the cameras and sensors with Chicago’s 911 center, reports the Chicago Tribune. Chicago officials announced last September that the city would be adding 250 cameras to the 2,000 already in the city’s video surveillance system, which aims its cameras at public spaces. City officials say the grid, which should be completed by mid-2006, will necessitate the addition of even more cameras.
