The glasses are connected to an internal database of suspects, meaning officers can quickly scan crowds while looking for fugitives.
The sunglasses have already helped police capture seven suspects, according to Chinese state media.
The seven people who were apprehended are accused of crimes ranging from hit-and-runs to human trafficking.
The technology allows police officers to take a photograph of a suspicious individual and then compare it to pictures stored in an internal database. If there is a match, information such as the person’s name and address will then be sent to the officer.
An estimated 170 million CCTV cameras are already in place and some 400 million new ones are expected be installed in the next three years.
Many of the cameras use artificial intelligence, including facial recognition technology.
