The cities with the most surveillance cameras in the word per capita are all in China, except for London and Atlanta, Ga.

Researchers from Comparitech studied the number of security video cameras in use in 120 major cities around the world and compared those numbers to the population of each city.

Chongqing had the highest rate of security video cameras, the report said, with about 168 for every 1,000 people. Shanghai had the overall most cameras, with more than 2.9 million, but its higher population meant it had only 113 cameras per 1,000 people.

China reportedly has about 200 million CCTV cameras. But by 2022, the country is projected to have 626 million cameras, one camera for every two people based on its current population, according to the study.
