Imagine a world where almost everyone can be tracked, and everything can be seen by cameras linked directly to the Chinese government. The rapid growth of a little known Chinese manufacturer of high-powered surveillance technology has some people concerned that it’s no longer a theory. Hangzhou Hikvision Digital Technology, a company controlled by the Chinese government, is now the world’s largest supplier of video surveillance equipment, with internet-enabled cameras installed in more than 100 countries. Capable of capturing sharp images even in fog, rain or darkness, Hikvision claims its most advanced technologies can recognize license plates and tell if a driver is texting while behind the wheel. They can also track individuals with unrivaled “face-tracking” technology and by identifiers such as body metrics, hair color and clothing.
