Abstract: A surveillance apparatus (2000) includes a first calculation unit (2020), an extraction unit (2040), and a notification unit (2060). The first calculation unit (2020) calculates a risk index value in a first region (40) on a current route (20). The risk index value of the first region (40) indicates a degree of concern that a risk (such as crowd confusion) caused by congestion of people occurs in the first region (40). For calculation of the risk index value in the first region (40), a captured image generated by a camera (50) is used. The extraction unit (2040) extracts a bypass route (30) when the risk index value of the first region (40) is equal to or greater than a predetermined threshold value. The notification unit (2060) notifies a user that a route through which a person is caused to pass is to be switched to the extracted bypass route (30).

Abstract: A surveillance system (1) includes an area information acquisition unit (101), a position information acquisition unit (102), a candidate determination unit (103), and a notification unit (104). The area information acquisition unit (101) acquires information of a surveillance-desired area. The position information acquisition unit (102) acquires pieces of position information of a plurality of portable terminals (20), each portable terminal performing surveillance using an image capturing unit. The candidate determination unit (103) determines a candidate portable terminal (20) to be moved to the surveillance-desired area from among the plurality of portable terminals (20) based on the acquired pieces of position information of the plurality of portable terminals (20). The notification unit (104) outputs a notification to the candidate portable terminal requesting to move to the surveillance-desired area.

Abstract: An information processing apparatus (2000) includes a first analyzing unit (2020), a second analyzing unit (2040), and an estimating unit (2060). The first analyzing unit (2020) calculates a flow of a crowd in a capturing range of a fixed camera (10) using a first surveillance image (12). The second analyzing unit (2040) calculates a distribution of an attribute of objects in a capturing range of a moving camera (20) using a second surveillance image (22). The estimating unit (2060) estimates an attribute distribution for a range that is not included in the capturing range of the moving camera (20).
