This is an ICU real-time smart care system that is installed in single-person households for the elderly living alone, the severely disabled, and vulnerable groups to detect falls, fires, break-ins, occupancy, and suicide attempts to save precious lives. In the event of an emergency, we notify the emergency within the golden time (1 minute), thereby reducing welfare blind spots and lonely deaths and achieving true welfare. In preparation for the upcoming super-aging society, it is an efficient system that can monitor 24 hours a day, detect emergency situations, and send emergency notifications in real time, allowing care and management on behalf of people.
