Smart cameras help to solve and prevent crimes in Shenzhen

Where is the least likely place that criminals would dare to go in the world? Probably China's Shenzhen. Why? Because it only needs a few seconds to locate a criminal among millions of people after the city's surveillance cameras were embedded with intelligent chips in November.

"In 2018, Shenzhen will be probably the safest city in the world," says Chen Ning, who helps maintain the intelligent-camera system for Shenzhen's public security bureau in Longgang district.

Like God's Eye in the movie The Fast and the Furious 7 that can track a target through all the cameras in a city, Chen's intelligent-camera system can detect a criminal in less than a second once he's in view of the lens.
