-P The SiBell units are not the Elite series but they will do the same thing. On the remote recorder, we need to be sure you are running the latest firmware. The new firmware , when you go to 'Manual Add' on the camera page, you'll get a header to 'Add Recorder'. If you don't see that, then we need to do a firmware upgrade on it. Otherwise, yes, the SiBells will do that.
I am not clear on what you are asking about the local target for Onvif devices. The recorder is Onvif compatible, and can be used to record most Onvif compatible cameras.
You could be receiving channels from the remote DVR/NVR as well as local Onvif cameras at the same time.
Let me know if that answer makes sense!
