Cameras are placed in more than 10,000 public areas and send surveillance feeds to police in real-time, identifying individuals, their family members and where they've been in the last week. A BBC reporter tested the system in December and was identified and captured within seven minutes. China has hit back at concerns over privacy, saying that there are no problems because the data is collected in "public places." An expansive facial recognition network in the southwestern Chinese city of Guiyang have reportedly enabled police to detect and apprehend criminals in as little as two minutes. The surveillance cameras are set up in more than 10,000 public places across the city, which is larger than the state of Delaware, reported the state-run newspaper Global Times this week.
