In Breña, Peru, local authorities inaugurated a Citizen Security Monitoring Center (CECOM) utilizing 40 intelligent cameras. The district intends to expand this network to 200 devices by the end of the year, employing artificial intelligence and facial recognition to identify individuals involved in criminal activities and interconnecting with the National Police of Peru. In Buenos Aires, Argentina, the city government is initiating a bidding process to reactivate a facial recognition system. This technology had been suspended for four years following a 2022 judicial ruling that declared its implementation unconstitutional. Human rights organizations, such as CELS, have expressed concerns regarding the previous application of the system, alleging it was used to create “arbitrary lists involving approximately 10 million people” instead of being limited to locating fugitives. ## Timeline ### 2026-10-27: Buenos Aires announces urban infrastructure and AI transit projects Buenos Aires is launching underground parking projects in several plazas to increase green space and implementing AI holographic avatars in Line B subway stations to assist passengers. 2 sources. https://clstr.news/cluster/buenos-aires-announces-urban-infrastructure-and-ai-transit-projects ### 2026-09-30: Surveillance technology expansion in Breña and Buenos Aires Authorities in Breña, Peru, are expanding AI-powered facial recognition surveillance, while Buenos Aires, Argentina, faces legal and human rights challenges in its attempt to reactivate a similar system. 9 sources. https://clstr.news/cluster/surveillance-technology-expansion-in-brea-and-buenos-aires --- Cite as: Surveillance technology implementation in South America.
