One of the constituent devices of a video recording/delivering system can be replaced with a generic IT device, without impairing functions which are implemented by the entire video recording/delivering system by using a dedicated protocol specialized for the video recording/delivering system among the devices which constitute the video recording/delivering system, thereby reducing the cost of the video recording/delivering system. Each network camera receives a video data delivery request, which is transmitted from a network camera control terminal by using a dedicated protocol specialized for a video recording/delivering system, by using the dedicated protocol specialized for the video recording/delivering system and delivers, in response to the video data delivery request, currently captured live video data, or video data which are obtained from a storage device by using a general-purpose protocol, to the network camera control terminal by using the dedicated protocol specialized for the video recording/delivering system. |
