International. Comparitech, a website that delivers consumer information and specializes in cybersecurity, this year delivered the results of its research on the number of CCTV cameras in the world's top 150 cities.
To obtain the results, Comparitech researchers compiled various resources, including government reports, data on police websites and news articles. As the company indicated in the publication of the results, "we focus mainly on public CCTV: cameras used by government entities such as law enforcement."
Overall, their study found that Chinese cities have the "most intense CCTV surveillance in the world." However, there was also a worldwide trend of increasing video surveillance.
One of the benchmarks of Comparitech is that, in 2019, the company IHS Markit indicated that by the end of 2021 there would be one billion surveillance cameras globally, of which 54% would be located in China, which would be equivalent to 540 million CCTV cameras, or 372.8 cameras per 1,000 inhabitants.
However, although China returned to take the first places, for its large investment in surveillance, there are other countries that have notoriously reinforced their video surveillance, hence several Indian cities, London, Los Angeles and New York stand out for their indicators.
Indore, Hyderabad, Delhi, Chennai, Singapore, Moscow, Baghdad, London, St. Petersburg and Los Angeles are the 10 most monitored cities outside China (based on the number of cameras per 1,000 people)
• Delhi, Chennai, Singapore, Seoul, Moscow, London, New York, Hyderabad, Mumbai and Mexico City are the 10 most monitored cities outside China (based on the number of cameras per square mile)
• By the end of 2021, it is estimated that more than one billion surveillance cameras were installed worldwide, according to the latest IHS Markit report.
• 54 percent of the world's cameras are located in China.
• We found little correlation between the number of public CCTV cameras and crime or security."
Latin America Data
Regarding the 10 most monitored cities in the world, excluding Chinese data, we find Mexico City, as the Latin American city with the highest surveillance, the specific indicator is that it has 80,000 cameras for 573 square miles, or what is equal 140 cameras per square mile.
In other data, corresponding to Latin America, apart from Mexico City, which ranks first with the data already exposed, it is followed by Rio de Janeiro (Brazil) with 45,571, Bogotá (Colombia) with 33,293, Guadalajara (Mexico) with 25. 699 and São Paulo (Brazil) with 23,415. These are the 5 cities with the highest rates in the region.
