Solid neighbourhood-bakery energy. Trustworthy and warm.
Summary
China is upgrading its nationwide surveillance system by equipping millions of old cameras with AI-powered computer vision and language models from manufacturers like Hikvision and Huawei. This allows police to automatically detect crowds, suspicious behavior, and unauthorized access through text queries instead of manual footage review. The Financial Times reviewed procurement documents and spoke with industry insiders to confirm the scale of this modernization. Human Rights Watch warns this enables unprecedented behavioral surveillance at scale, going beyond the earlier facial recognition and license plate scanning systems deployed since the mid-2010s.
