From August 30 to September 2, in Brasilia, the 4th Security Symposium was held. It is an event for the top-level executives of various Brazilian law enforcement agencies, intelligence agencies, and other organizations responsible for ensuring national security. Our Brazilian team’s presentation “Facial recognition: Architecture and operational vision of a large scale system” aroused the keen interest of the attendees. The NtechLab booth, where colleagues demonstrated the multi-object video analytics technology, has attracted more than 100 interested visitors in two days, including heads of various regional police departments and journalists.
