Rio de Janeiro and Salvador will test during this year's Carnaval a system of facial recognition installed in street security cameras. The goal is to allow law enforcement to monitor the festivities remotely and identify people with arrest warrants, police records, and missing persons.
The system is also capable of recognizing license plates.The systems adopted in each city are different from each other. In Rio, 100 police officers will be on duty in a central headquarters, that will receive feeds from 28 street cameras in the neighborhood of Copacabana.
The images will be compiled and transmitted to HQ, and the officers will compare them with police and DMV databases.In Salvador, the system will be the same used in China, in which the cameras already have facial recognition software.
The 42 entryways to the main Carnaval routes - Barra, Campo Grande, and Pelourinho - will be equipped with cameras.In total, there will be 26,000 officers and 430 cameras, with 360° and wide angle lenses, and capable of a 45x zoom, and low-light sensors.
