On the other hand, CCTVs are also pretty rare

No, CCTVs are almost everywhere. The average person is on them dozens of times if not scores of times a day.
As of 2017, London police had 51,000 cameras up, though estimates of surveillance cameras run to about 500,000 in London. This almost certainly does not include all private surveillance and 'incidental' surveillance by webcams, dashcams, babycams, etc. A second source cites 420,000 surveillance cameras in London, and 1,850,000 cameras in the UK. One estimate projects 642,000 surveillance cameras in London by 2020. This probably does not include the proposed plate reading cameras every 400 meters along public highways, over the entire country, and probably doesn't include the 'congestion' cameras reading all the vehicle plates going in and out of downtown London.
Beijing had a network of 43,000 police cameras, and on Chinese National Day holidays in 2015 monitored 8 million people over 4 days. Another source cites 400,000 surveillance cameras in Beijing, according to the Beijing Security and Protection Industry Association.
Chicago had about 10,000 police cameras watching public spaces. There are probably hundreds of thousands of privately owned CCTV cameras in the city. Another source cites 17,000 cameras installed as Operation Virtual Shield, a Homeland Security project in Chicago.
Houston is estimated to have about the same number as Chicago, but they refuse to tell anyone how many they have.
New York police had about 6,000 cameras watching public spaces. I wouldn't be surprised to find half a million private surveillance (aka 'security') cameras in that city, plus the incidental cameras, of course.
Chongqing has a plan to deploy 500,000 cameras in that city, as an integrated network.
The 2016 estimate for worldwide surveillance camera count was 350,000,000 in 2016, up from 160,000,000 in 2012. By my math, that's an extra 45,000,000 cameras every year.
The US recorded sales of 30,000,000 security cameras over a ten year period.
South Korea is estimated to have about a million CCTV cameras watching public places, as of 2017.
