I live in the UK with a high use of cameras for everything. For speed it clearly works where there is an actual camera (it works less well between cameras). For crime there’s some evidence it might have a deterrent effect on property crime and drug crime. There is very little evidence to show that it has had any effect on violent crime, public disorder offences, and the like. There’s also an argument that over-reliance on cctv has reduced the kind of policing people most favour – community policing. The government has recently banned Hikvision cameras (one of the most ubiquitous brands) from its buildings over concerns about the Chinese company’s use of data and their role in the oppression of Uyghur Muslims in Chinese state run “re-education camps”. Cameras can be useful in certain circumstances, but their efficacy is often overstated, and there are many downsides.
