Muralha BH: Citywide Facial-Recognition and License-Plate Camera Network

Announced on 6 October 2025, Muralha BH is Belo Horizonte's rollout of an intelligent camera network targeting 8,000 cameras — 1,890 with 360° rotation, 2,650 reading license plates and 1,500 running facial recognition — installed at plazas, parks, health centres, schools and major roads, with full deployment targeted for the end of 2026. About 600 cameras were installed and tested in the program's first phase, with roughly 1,000 expected online by December 2025; footage is monitored through COP-BH. Rather than build its own matching system, the city sends facial-recognition feeds to a Polícia Federal platform (integration reported in July 2026) that checks for outstanding arrest warrants and missing persons and issues alerts for federal officers to validate — no accuracy, false-match or arrest figures have been published for either the municipal camera network or the federal matching pipeline.

🎓 Lesson

Outsourcing the actual facial-recognition matching to a federal partner does not make the accountability question go away — it just moves it to an agency the city does not have to answer to.
