Brazil is following China's example and adopting facial-recognition technology to crack down on crime. As a result, the country represents a potentially lucrative market for surveillance systems manufactured in China.

In 2018, the Brazilian city of Campinas began using Huawei's facial-recognition cameras with the goal of "replicating" the company's "advanced public safety" model for smart cities, using artificial intelligence (AI) to sift through a dataset of biometric information, personal data, and social media images. When the AI identifies someone as a wanted suspect, the system notifies authorities via mobile phone so they can quickly arrest the individual.

Human Rights Watch researcher Maya Wang said no “compelling evidence” exists that such systems improve safety, adding that in an environment where lawmakers are still catching up on the capabilities of the technology, "it's easy for surveillance companies to move in."
