I very deliberately selected non-cloud cameras for this project. I already had a baby monitor that
was cloud-based and liked that not at all. Since the zm setup is for internal use only, I have set
up the cameras and the server on a separate isolated subnet we can get into but nothing inside can
get out. If I want to upgrade the server I have to power it off, unplug it and plug it into another
subnet in order to do it.
Thank you very much for the above information. The zm server of course has an Apache component so I
can serve the .m3u file from there easily enough.
