US-based Cisco Systems Inc and Hewlett-Packard, along with a handful of other Western technology companies, are set to provide crucial network equipment for a massive CCTV surveillance project in the city of Chongqing. Known as “Peaceful Chongqing” the network of about 500,000 cameras will spread over nearly 400 square miles, it will police intersections, neighborhoods and parks. Chinese officials say the added surveillance will prevent crime but human-rights advocates fear it will be used to silence political dissidents.
