(South China Morning Post) The surveillance tools are identical to those used in Sky Net in China, the largest video surveillance system on Earth, Chinese government research institutes and a company involved in the project said.

At a time when China and the United States are locked in a rivalry on several fronts including trade and technology, Hikvision – which is the world’s largest surveillance technology company and based in Hangzhou in eastern China – has supplied the equipment and software used by an American force that polices a population of about 8.6 million people.

It has been claimed that Hikvision’s system can accurately identify faces regardless of race, whereas some Western-developed technology had previously been more accurate for white people than for black citizens – although the NYPD has not discussed its reasons for using the Chinese technology.
