When an access request (a request for transfer of video and audio information or a request for a camera operation) to a camera apparatus connected to a network via a terminal is issued via the network, a camera management server processes the access request on the basis of an access right set by a user (or a manager) using the terminal to which the camera apparatus is connected. That is, the camera management server refers to an access right set file and grants or denies permission to access for the user whose has issued the access request. The user to whom the access permission is granted requests a camera control server to permit a camera operation via a camera control client and thereby can receive an image taken by the camera apparatus and voices collected by the camera apparatus and can perform panning, tilting, and zooming of the camera apparatus. Accordingly, to protect the privacy of a user using a terminal to which a camera apparatus is connected, it is possible to realize fine setting meeting the demand of the user at all times. Also, in a location where a camera apparatus connected to a network is installed, it is possible to prevent a leak of confidential information through the camera apparatus.
