Abstract: An action detection unit (110) analyzes monitor data obtained by monitoring a monitoring place, and detects a relevant action performed at the monitoring place and having a characteristic that is common to a violating action. A situation analysis unit (120) analyzes visual data obtained by photographing the monitoring place, and detects a surrounding situation of an action position equivalent to a position where the relevant action was performed. The situation analysis unit decides a nuisance degree of the relevant action on a basis of the surrounding situation. A presentation control unit (130) determines an alert level on a basis of the nuisance degree. The presentation control unit presents presentation information corresponding to the alert level with using a presentation apparatus installed at the monitoring place.
