  • Publication number: 20240233505
    Abstract: In a first example, a user himself/herself sets an area in which the user desires to observe an observation target, a content of an anomaly state of the observation target that the user desires to be notified of, and a sensitivity of the notification of the user with respect to the content. When a state of the observation target corresponds to the anomaly state, occurrence information on the anomaly state is notified to a pre-registered user terminal. In a second example, the user himself/herself sets the area, a content of an anomaly relation between the observation target and a moving object around the observation target that the user wants to be notified of, and the sensitivity. When a relation between the observation target and the surrounding moving object corresponds to the anomaly relation, occurrence information on the anomaly relation is notified to a pre-registered user terminal.
