Researchers Determine the 120 Most Surveilled (CCTV) Cities In the World (comparitech.com) 47

dryriver writes: Comparitech.com has published a report and spreadsheet laying out how many CCTV cameras are in operation in 120 different cities around the world, and data for the crime rates in these cities. The report notes "We found little correlation between the number of public CCTV cameras and crime or safety."

8 of the 10 most surveilled cities are in China, even though London and Atlana also make the cut, and the report says that — depending on what numbers you believe — China will have between 200 Million and 626 Million CCTV cameras, or possibly even more, in operation by 2020. That would be almost 1 CCTV camera per 2 citizens in the country, and the number could go up.

Outside of China, the top most-surveilled cities in the world are:
  • London - 68.40 cameras per 1,000 people
  • Atlanta - 15.56 cameras per 1,000 people
  • Singapore - 15.25 cameras per 1,000 people
  • Abu Dhabi - 13.77 cameras per 1,000 people
  • Chicago - 13.06 cameras per 1,000 people
  • Sydney - 12.35 cameras per 1,000 people
  • Baghdad - 12.30 cameras per 1,000 people
  • Dubai - 12.14 cameras per 1,000 people
  • Moscow - 11.70 cameras per 1,000 people
  • Berlin - 11.18 cameras per 1,000 people
  • New Delhi - 9.62 cameras per 1,000 people

With 4,000 cameras, Washington D.C. is #29 on the list. Other American cities include San Francisco (#39 with 2,753 cameras), San Diego (#43 with 3,600 cameras), Boston (#47 with 1,552 cameras), and New York City (#58 with 11,000 cameras). And the San Diego Union-Tribune reports that at least for their city the total "is likely an undercount, considering that San Diego police officials said they recently installed surveillance sensors on about half of a planned 8,000 'smart' street lights."

Also on the list are Chennai India (#33 with 50,000 cameras), Auckland (#36 with 5,577 cameras), and Toronto (#44 with 14,955 cameras).

  • Some cities have a lot more transient traffic, so measuring cameras-per-citizen doesn't reflect the purpose.

    Cameras-per-square-meter would probably be more meaningful.

      I prefer murders per camera normalized to median household income.
    • According to the article, these figures are only for Public cameras. Not included are the many private cameras that businesses and people own that are facing the street, that police in NYC have requested feeds to the police HQ to add to the public cameras. And those additions are significant!
      • Totally agree. A city might have less public camera's if law enforcement knows the majority of shops will have cameras everywhere and will comply to their requests for a copy. Shanghai though, nearly 3M cameras: impressive. Like city full of stereotypical Japanese tourists from the 80's ;)

          I immediately knew that it was public cameras only. Moscow has about 1 car per 3 citizens, and at least 30% of those have a dashboard camera. That's 100 cameras per 1000 citizens right there.

          I do not know whether law enforcement can request the footage at will. What I do know is that quite a few cities of the US keep a few days worth of license plates that have crossed the major intersections. Combine that with dashboard cams, and when there is an accident, you could ask the owners of the cars in the n

        Brits love personal cameras because increasingly insurance likes to go 50/50 on any claims without video evidence.

    • by vlad30 ( 44644 )
      Interesting though the most surveillance is carried out in the most politically left leaning of places china has 8 of the top ten spots and had to be taken out of the list to then compare the rest. Now is that due to the high crime rate of left leaning citizens or that left leaning governments don't want you thinking for yourself ? Also careful in islamic countries those cameras will be used against you. Don't canoodle if your unmarried.

    I have no difficulty visualizing this occurring in China. I'm increasingly more concerned with regard to Western countries.

    • China they give you a social score. It isn't just crimes, or at least serious crimes they are after. Do you go to a church? Do you jay walk? If so minus points for you. Next thing you know you can't get permission to move to a city, or get a job etc.

  • It would be interesting to also quantify how the images are being used.

    For example, to what degree are the camera's connected to facial recognition algorithms?

    One city that has gone all-in on this is Mowcow, which would then put them higher on the list.

    • I agree - London has a lot of cameras, but it's unclear who they're connected to. Whilst (say) the police might be able to get to look at the vast majority for specific events, they don't get to run AI on them 24x7 - they could only do that on a very small number of them. Likewise, say, the traffic people could only do any sort of wholesale analysis of their own cameras and not so easily for anyone elses. Whilst we're indeed headed down the rabbit hole, at the moment we have lots of separate government and

      Well, I have at least 19 cameras just for me in my house, three of which are explicitly security cameras and another 7 of which would be trivial to configure in that role.

      Start adding private cameras into the mix and 1.3 per person feels remarkably low.

    I'm from Buenos Aires, and the population they used is grossly over estimated. The city has 2.89 M people, not 15M (that number probably includes the greater Buenos Aires area). If they counted the cameras right, the average is 3 cameras per 1000 people.
  • "surveilled" - interesting new word. A back-form derived from surveillance, I assume?
    I'd complain about the tortured things you Americans do to our language, but since we stole "Surveillance" from the French, we are not on high moral ground.

    Moscow has all of the CCTV cameras wired into a tracking system with face recog. They also know how to use it. https://www.fagain.co.uk/node/...

  • CCTV has become not only "security theater", but something approaching self-parody.

    Here are the issues with CCTV:-
    1. They Are Only Useful After-the-Fact
    As demonstrated by the London 7/7 bombings, the Boston Marathon and the Paris attacks, the single most useful thing CCTV offers is the ability to back-trace, after an incident, to try and identify the culprits. Contrary to popular arguments, CCTV does not act as an effective deterrent, because those determined to commit crime or cause harm will simply f
    • Contrary to popular arguments, CCTV does not act as an effective deterrent

      DO you have data for that claim?

      There is a paradox. Before any CCTV (20, 50, 100 years ago, whatever) some areas had far more crime than others - orders of magnitude. Suppose in a high crime area like Bogville you had installed CCTV and the crime has dropped to half. The crime rate would still be higher than in many low crime areas without CCTV, say in Sylvania. But people could claim that CCTV is ineffective because crime rate with CCTV in Bogville is higher than without CCTV in Sylvania.

        Yes.

        1. The London attacks of 7/7. The perpetrators were caught on numerous CCTV cameras, both on the day of the attacks and during their reconnaissance visits.

        2. The Boston Marathon attackers were caught on multiple cameras - both municipal and private - and went ahead with their plans regardless. They carried on with their plans, regardless.

        3. The Paris attackers not only knew that the were being monitored, but they crafted their practices to blend in. After the back-traces that took place, the Fr
        • I get it, you are thinking/talking about major world-headline crimes like suicide bombings and other terroist attacks. That's not what the vast majority of CCTVs are for, they are to deter petty crime like vandalism and mugging, and to help nail the perpetrators (which they are very successful in doing).

          When a CCTV is put up outside a small parade of shops in an outer London suburb, it is not for a policeman to watch a screen 24/7 for signs of a suicide bomber, so as then to rush out and build sandbags

          These are anecdotes, not data.

          With the same reasoning, we can prove that locks are useless. Most burglaries happen when the door is locked, but that's just because very few people leave their door unlocked. You need to do proper analysis in order to evaluate the usefulness of something. For locks, insurance companies did their research. And that's why they are telling you to lock your door.

          The effect of security cameras are difficult to judge.
          - You know when security cameras are ineffective as a deterrent,

    • Yeah, the only way cameras can be useful for preventing things is if they were being analyzed in real time by incredibly sophisticated AI software that simply doesn't (AFAIK) exist today. Employing people to monitor them wouldn't just be very expensive it would likely not work either since people can only pay attention for limited amounts of time.
      While I support the usage of CCTV to solve crimes there will always be a dark side to it since you can't prevent people misusing them, corruption, etc.
    • by AmiMoJo ( 196126 )

      Funny how the cameras on the London tube were not working the day that the police murdered a guy, only days after the 7/7 attacks. Shame they didn't capture that time police officer Simon Harwood covered his face and badge number and murdered some random passer-by during the G-20 protests either.

  • I am not surprised at all, laws here in Singapore are extremely strict. You can even be in a lot of trouble for making a mistake in your advertising if you're in the Health field for instance, like this doctor did https://healthmark.sg/blog/doc... [healthmark.sg]. It's quite severe but it is better for consumers and citizens in general.
