To provide an action monitoring system which improves privacy protection of a person to be monitored.SOLUTION: An action monitoring system 10 transmits the detection result of a specific action to a terminal device 70 in the case where a specific actin of a care-receiver is detected. The action monitoring system 10 includes: an imaging device 20, installed in a habitable room 100a, for imaging a care-receiver associated with the habitable room 100a； and a control device 40 which transmits a first image based on a base image imaged by the imaging device 20 to the terminal device 70 in the case where a predetermined operation from the care-receiver is detected, and which transmits a second image which is the second image based on the base image, whose image quality is further deteriorated than that of the first image and which can specify the specific action of the care-receiver to the terminal device 70 in the case where the specific action of the care-receiver is detected.SELECTED DRAWING: Figure 2【課題】被監視者のプライバシー保護が向上する行動監視システムを提供する。【解決手段】行動監視システム１０は、被介護者の特定行動を検知した場合に、当該特定行動の検知結果を端末装置７０に送信する行動監視システム１０であって、居室１００ａ内に設置され、当該居室１００ａに対応付けられた被介護者を撮影する撮影装置２０と、被介護者から所定の操作を検知した場合、撮影装置２０が撮影した基画像に基づく第一の画像を端末装置７０に送信し、被介護者の特定行動を検知した場合、基画像に基づく第二の画像であって、第一の画像より画質が劣化し、かつ被介護者の特定行動を特定可能な第二の画像を端末装置７０に送信する制御装置４０とを備える。【選択図】図２
