Abstract: Provided according to the invention is a recording control apparatus capable of more accurately recording an image of a person carrying an article to which an RFID tag is attached. When a reader/writer receives position information on an RFID tag attached to an article, this information is stored in an article information storing section. When a position determining unit detects an article located out of a designated area, a monitoring camera control section starts controlling recording. The monitoring camera control section estimates the movement direction of the article based on the time-sequential record of the position information on the article, specifies any of monitoring cameras to be operated based on the movement direction and the current position of the article, and controls the recording operation of the specified monitoring camera.
