What US city has the most CCTV?

Which US city has the most CCTV or security cameras is difficult to determine precisely because many cameras are private and not publicly counted, but estimates based on public safety cameras, traffic cameras, and private security camera density suggest New York City has the most CCTV cameras in total numbers due to its large population, extensive subway system, businesses, and high security presence, with estimates of over 50,000 public and government cameras and millions of private cameras. For cameras per capita or per square mile, some studies rank Chicago as having highest density of public surveillance cameras in US with extensive network of over 30,000 police cameras in Operation Virtual Shield plus private cameras. Other cities with high camera counts include Los Angeles, Houston, and Washington DC due to federal buildings. For government owned cameras alone, New York and Chicago consistently top lists. For private cameras per person, smaller high crime cities may have more. Some reports list Atlanta, Philadelphia, and San Francisco as highly surveilled. Exact numbers change yearly as cities add cameras, and many estimates include both government and private cameras from businesses and homes, so ranking varies by methodology.
