Citizens of India and China are the most closely watched thanks to an incredible number of surveillance cameras set up in the big cities of the two Asian countries. Beijing counts over a million devices, while Indian inhabitants of Chennai are the most closely monitored thanks to over 650 CCTV cameras set up per square kilometer.
Since the first surveillance cameras were installed during the Second World War, their number has continued to grow... even hitting the symbolic milestone of a billion in 2021!
