ATL is the fraud capital of the USA and they're really only counting the tiny part of true Atlanta. San Diego has NBSD and several large shipyards in a small area.
As a San Diego Native and Resident, the cameras are part of a city wide project to put "Smart StreetLights" all around the City. They don't monitor anything specific but are used to gather evidence for crimes. San Diego does not actively monitor the videos from the camera.
