A video transmission apparatus (100) detects a target object to be monitored from a plurality of images obtained by imaging a monitoring area, tracks the detected target object, obtains existence time from appearance to disappearance of the target object, and transmits a data volume reduced image of the target object to a video reception apparatus (200). The video reception apparatus (200) analyzes the data volume reduced image transmitted from the video transmission apparatus (100) and transmits a video request of the target object to the video transmission apparatus (100) based on input made according to the result of the analysis. When the video request transmitted from the video reception apparatus (200) is received, the video transmission apparatus (100) generates a monitoring video from the appearance to the disappearance of the target object based on the existence time of the target object and transmits the monitoring video to the video reception apparatus (200). This can prevent a situation in which a necessary video is not transmitted and an unnecessary video is transmitted. |
