Transcending the global Smart City agenda, Cognisense (patent pending) is a cognitive IoT and analysis platform that captures citywide data via a meshed sensor array that provides deep longitudinal insights into a city's activity, liveability and environment. Unlike current empirically modeled or vertically focussed IoT solutions Cognisense creates a real-time holistic understanding, cognitive sense, of the city it monitors, guiding behavioral change, better policies and better quality of living.
