Tianjin, in northern China, is the country’s fourth most populous municipality after Shanghai, Beijing, and Chongqing, with more than 15 million residents. That kind of population density demands unusual measures to maintain public order and security.
That may be exactly what local administrators had in mind when they decided to equip the city’s police with smart glasses capable of identifying people, managing traffic, and tracking down fugitives. It is a step toward the future of surveillance, and at the same time an enormous ethical problem for privacy and freedom of movement.
How the smart glasses work
The Chinese officers’ smart glasses have a facial-recognition accuracy above 95% and “respond” within a few milliseconds. They weigh roughly 40 grams, and the battery lasts between one and two hours of continuous use.
The device is produced entirely in China, both the hardware and the software.
Beyond the design and the technical specs, it is the features that stand out. The “smart” glasses are deployed for traffic management, patrol, and urban security thanks to their ability to recognize text, interpret voice commands, scan the surrounding environment, and pull answers from a connected database.
The first real-world applications
Officers’ first accounts to local media have been enthusiastic. An officer from the Jiefang Street precinct said the glasses let him identify an elderly man who was disoriented and unable to speak, and return him home in just 20 minutes.
The results in managing traffic outside schools have been strong as well. Parents can pre-register their vehicle’s license plate on a platform that the glasses can “consult” in real time.
That allows officers to recognize authorized vehicles, manage drop-offs to keep children safe, and divert other cars during peak hours.
The future of surveillance and the privacy risks
Smart glasses with facial recognition had in fact already been used in China back in 2018, when at the Zhengzhou East railway station they delivered strong results in locating fugitives and detecting cases of identity fraud.
That, however, was an isolated episode tied to the Lunar New Year, a moment of extreme population movement across the country.
This time, by contrast, we are talking about an element built into a full-fledged urban-security ecosystem. And all of that only heightens privacy concerns. The glasses make it easier to identify missing individuals and help reduce the number of accidents. But in exchange they “ask” citizens to hand over their personal data and their vehicle plates.
And the coming arrival of robotic dogs, humanoid robots, and intelligent police vehicles could make the situation even more complex, stripping Chinese citizens of the last shreds of freedom they have managed to hold on to.
