I’m trying to figure out the RTS NAS configuration. The linked page is written in jargon. Is the base an NAS? What is Synology?
Remembered this article but eufy community may have additional info
@pag1 Synology is a brand of NAS and storage servers. The Homebase itself is just a controller with internal storage for your camera footage.
The link posted by @Duane_Lester will help you through the steps to use your existing NAS drive (if you have one) as a storage resource.
