I have several cameras with Onvif profile S. Each has the current firmware installed.
It seems there is no possibility to configure the recording target by using the Onvif interface on this profile? (I found it in the core specifications, but the cameras are responding with errors on that method)
But it seems strange, since it's possible to configure the recording target by using the GUI and the vendors own API. (I have Axis and Samsung cameras)
Okay, I have an answer for my question.
Onvif defined the methods for configuring storage settings in the newest version, 2.5. Since my newest camera with the current firmware only supports 2.1, I simply do not own any camera with support for storage configuration and so I need to wait until the vendors implement the methods from newer specifications.
