These days, almost anything could be hiding behind the term "Smart City". "For me, it is about continuing to drive forward what has always set Hamburg apart – the combination of technological and social progress. Through numerous projects, involving many different partners, we are currently laying the foundations for the smart city of the future, for a city that uses technology to conserve resources and to keep in close touch with its people", said Olaf Scholz, the First Mayor of the City of Hamburg, at the signing of the Smart City Memorandum of Understanding (MoU). These projects generate technical, economic and social innovation. This innovation includes the use of video collaboration solutions in the public sector.
