The system allows you to import objects from other servers, as described in the Object Import topic, but the system offers extra options for importing cameras:
Import cameras from a remote server (copy): When the import is made as a copy, the settings will come exactly as from the imported server. An important example is the recording unit: if on the source server the cameras are recording in the E: directory and on the current server this unit does not exist, the camera will not record.
Import cameras from a remote server (relay): When the import is done as a relay, the current server will register the cameras with the Digifort RTSP Server driver, which in this case will fetch the images from the source server.
See the Object Import topic for more information on how to import objects.
