I would like to test it alongside our existing 2 Reolink cams (RLC-511 & RLC-511W)

We are learning the foibles of the RLC-511. Really like the zoom to 30-degree field of view.

YES to the idea of "FTP automatically create subfolders ... yyyy-mm-dd format".
Variations of that are pretty much standard with every other cam I have used.

And the local storage of mp4 is bizarrely mmddyyy, meaning that when 2018 became 2019 the old year came AFTER the new year in the folder ...
