NVR connectivity seemingly so poor I attach my Cameras to a POE Switch

All my equipment is brand new and while having the NVR https://reolink.com/product/rln8-410/ everything was just extremely confusing and problematic with the cameras directly connected to it. So I took the NVR off line. Connected my cameras ( 2 x https://reolink.com/product/rlc-843a/ for now) to my PoE Switch and suddenly everything was a lot more stable and I could do the relevant FW upgrades without interruptions or timeouts or resetting the cameras 4 times in a row.

(I should mention that the cables connecting the cameras to the NVR were the exact same cables that connect them to the PoE Switch.)

So now I am slowly experimenting to set up the cameras (Manual? Recommended settings?) and storage might become an issue. I have 128GB SD Cards for all and while that is normally a respectable amount of storage it will of course not last very long. Enter the NVR. Oh, found a manual: https://home-cdn.reolink.us/wp-content/assets/multiple-languages/manual/Reolink_Client_User_Manual.pdf?download_name=Reolink_Client_User_Manual.pdf

I have taken the NVR online again, but not connecting the cameras. It connects to my network via the very same PoE Switch.

How do you suggest I tell the cameras to use the NVR to store the media? I do not seem to find any menu alternative or setting for that, despite NVR being available (when connected) via the Android App as well as the Windows Reolink software.

EDIT ( since I still cant make new posts without a random thousand of seconds between them)

And such a curious little nuisance, does a camera hard reset restore the old firmware that I spent a LOT of time trying to get updated... certainly looks that way...?

@joseph_1979 so what good is an NVR if I do not connect the cameras to it or need it for storage?
