A camera terminal including an imaging zone adjusting apparatus that adjusts an imaging zone using multiple camera terminals, a camera that images a hypothetical imaging zone obtained by changing the position of an imaging zone within a specific zone in a specific period of time, an adjusting unit that adjusts the position of a hypothetical imaging zone, and a communications unit that sends/receives hypothetical imaging zone information indicating the hypothetical imaging zone. The adjusting unit adjusts the position of the hypothetical imaging zone of one's own camera terminal based on the hypothetical imaging zone of one's own camera terminal and the hypothetical imaging zones of the other camera terminals indicated by the hypothetical imaging zone information received by the communications unit so that a combined zone of the hypothetical imaging zones of the multiple camera terminals completely covers a specific imaging target zone.
