This is a secured IoT-based video surveillance management system that can collect and analyze data across various application systems such as environmental control, energy monitoring, access management, fire alarm, smart transportation, industrial inspection, regional disaster emergency communication networks…, etc. The IoT infrastructure of such a platform allows a smooth flow of information not only among the systems connected within the community, but also the public information platform such as the “Civil IoT Taiwan.” This way, the functionality of the surveillance system in normal days can be easily extended to a community-based disaster prevention application, as a value-added service, by issuing alarms before the disaster, notifying evacuation route during the disaster and providing crucial reference data for recovery initiatives.
