We are constructing intelligent city management more quickly and using massive video resources of cities and advanced technologies such as AI, big data, and cloud computing to create a management flow including “acquisition, review, reminding, handling and closing”. Our powerful R&D team has developed AI algorithms for environmental hygiene, orders on streets, city appearances, risk events, safe operation, public facilities and so on, changing management-oriented smart cities into service-oriented ones and creating a new smart city management system with multiple acquisition modes, extremely simple flows, and intelligent operation.
