The PRC has a lot more CCTV, slightly less per capacita, but that's irrelevant if you account for density. They also have a lot more means to aggregate information at the municipal level and turn it into actionables, and they do so pretty openly. Meanwhile US cities and police departments are still in love with a glorified spreadsheet provider.

Not that I'm advocating for any of this, but saying the PRC has less, or even substantially less surveilance than the US is a pretty laughable proposition.
