V2 "re-enrolled" like a new cam?

Have a V2 that I replaced with a V3. So it sat idle for a couple weeks and I found another place for it. Fired it up and it works fine. However; the app and such treat it as a NEW camera - got the trial for CamPlus and all that. Kind of strange… Just wondering if the Person Detection I already had on that camera will still be effective once this CamPlus trial concludes…

You can remove the Cam Plus trial from the V2 cam that just got it, and apply it to any other cam. No, once you have Legacy Person detection (closed a long time ago), you can apply that to any V2.
