CCTV Cameras Watch Over an Intersection in Beijing, China

Closed circuit television (CCTV) cameras watch over an intersection in downtown Beijing on Sunday, February 28, 2021. Chinese scientists have developed a 500 megapixel facial recognition camera four times more detailed than the human eye that can identify individuals from crowds of tens of thousands in streets or at sports stadiums, it was revealed by researchers at China's International Industry Fair. China currently has an estimated 200 million CCTV cameras watching over its citizens. Photo by Stephen Shaver/UPI
