Cities across China have debuted crime-fighting facial recognition technology to much fanfare over the past year. But some of these jaywalker-busting devices aren’t as impressive as they seem.

A facial recognition system in the city of Ningbo caught Dong Mingzhu, the chair of appliance-making giant Gree Electric, running a red light. Only it turned out not to be Dong, but rather an advertisement featuring her face on the side of a bus, local police said on Weibo Wednesday.

The police said they have upgraded their tech to avoid issues like this in the future. The real Dong, meanwhile, is embroiled in drama with an electric vehicle company.
