I'd like to hear any recommendations and experiences please for face recognition software that can run on a centos server machine (command line only). What I'd really like is a program that runs in a web gui if such a thing exists. I'm ok with installing and compiling in a terminal but I don't like the idea of trying to configure such software in a terminal.
I already run several ip cameras in zoneminder (which runs in a web gui) and I'd like to pipe the same video feeds to a face recognition program as well if that's possible. I did a search on google about this but most results are only for windows machines and linux machines with desktop. Thanks for any advice.

almost all will be proprietary and closed source

but you can write the code and use OpenCV as a base
