The present invention is intended to manage a plurality of network cameras simply. The network camera management system comprises: a server for managing a plurality of cameras and controlling recording and/or displaying of an image captured by a camera; and a controller for instructing a management state of a camera on the server. By the operation of the controller, an image to be displayed is dynamically selected from images captured by the plurality of cameras according to the mode instructed by the controller. Thus, even if there are a large number of cameras, it is possible to display in such a form that it is intuitively easy to understand which camera's image is being displayed.
