Synology Surveilance Station [1], it supports 2 cameras per NAS for free, extra cameras $50 per device. I use an old 2 HDD NAS with 2 cameras for a few years already, it works perfectly well. (One Reolink camera, another Amcrest, both record video in h264).
This was a good answer, but Synology is making their new devices increasingly hostile towards non-Synology-branded HDDs.
Oh, I was not aware of this change. Hopefully, I just have to reject all software updates and continue running my 2 Synology NASes with cheap shucked WD drives inside.
