At Beijing Security Fair, an Arms Race for Surveillance Tech

At the fair, Reuters saw stalls offering cute-looking robots, equipped with criminal detection AI systems, as well as an array of drones, smart glasses, DNA software, and facial-recognition cameras.

The Chinese-made XDH-CF-5600 scanner - or "mobile phone sleuth", as sales staff described it when touting its claimed features - was one of hundreds of surveillance gadgets on display at a recent police equipment fair in Beijing.
