Henan foreign journalist, student surveillance

Video surveillance analysis company IPVM reports that the government of Hunan province in China is setting up - or has already set up - a system to detect and track 'people of concern' including foreign journalists, students, and migrant women. 

The system uses facial recognition technology supplied by local company Neusoft, and is connected to over 3,000 CCTV cameras across the province and to a number of national and regional databases. 

According to the Hunan government's 200-page tender document, the surveillance system uses a traffic light system to categorise targets by those considered to be of 'key concern', 'general concern', and 'not harmful'.

It is unclear whether the system is already operational.
