If BI would work on Linux, imagine how simple of a machine you would need. I’m thinking a lean linux mint running on an I5, compared to all of the windows bloat that needs to be running.
Anyway, I have BI running on an older Intel NUC that I had laying around - an I5. Has 3 cameras so far, 16 g memory and I have stripped windows 10 to bare minimum. So far, most that I have seen CPU was at 5%. I don’t use this computer for anything else. I have also set up the NUC with dual ethernet and the cams on their own network. All setup info that I learn from this site and the forums.
