A plurality of data storing servers 3 are connected on a communication network 6 . A plurality of cameras 2 connected with the communication network 6 are divided into a plurality of groups, and the respective groups are related to the respective data storing servers 3 in correspondence. The respective data storing servers 3 import images from the cameras 2 belonging to the corresponding groups and store the imported images. If a request for the supply of an image to the camera 2 or the data storing server 3 is entered by means of an entry unit 28 in a PC 4, information representing this request is transmitted from the PC 4 to the camera 2 or the data storing server 3 via the communication network 6 . Upon the request of the image from the PC 4, the camera 2 transmits an image obtained by a photographing operation in a target area to the PC 4 via the communication network 6 . Upon the request of the image from the PC 4, the data storing server 3 supplies a requested image stored therein to the PC 4 .
