I already have a home server, running various services, including Frigate which is constantly monitoring three security cameras (via ethernet).
I’m starting to look into the idea of ripping my DVD/Blueray collection and streaming it via Jellyfin, and that would likely be over wifi to the Roku attached to the TV.
My concern is whether this is too much bandwidth for one device. At what point does high-quality movie streaming impact the reliability of the security camera feeds? Is that line so low that it’s just best to use a separate machine for running Jellyfin?
Seconding this answer, I started typing up more or less the exact same response before scrolling down. Network will not be your bottleneck here. You are far more likely to have a storage or CPU bottleneck, but the only way to know is to try it.
