REMOTE MONITORING SYSTEM, REMOTE MONITORING METHOD, AND RECORDING MEDIUM

A remote monitoring system is a remote monitoring system that detects an anomaly in a state of a monitored target that operates autonomously, and the remote monitoring system includes: a state obtainer that obtains state information indicating a state of the monitored target from the monitored target; an information obtainer that obtains first sensing information indicating a result of sensing of the monitored target from an external information source that is provided outside the monitored target and performs sensing of the monitored target; a state estimator that estimates a first state of the monitored target based on the first sensing information; and a state comparer that compares the state information with estimated state information that is based on the first state.
