How much surveillance is too much? That is a question being asked in China after police in the country began using sunglasses equipped with fixed facial recognition cameras in order to help identify potential suspects, reports said Wednesday. Since the beginning of China's Lunar New Year travel season, police at Zhengzhou East Railway Station have already identified and taken into custody seven fugitives in connection with major criminal cases. They also identified 26 people attempting to travel using other people's IDs, according to Chinese state media reports. The smart glasses are said to be connected to an internal database of suspects, which means police officers can quickly scan crowds while looking for fugitives.
