hi, this is my first RPi (and my first message on any RPi dedicated fora) so I hope this is the right section for my question.
I would like to have 4 IP cameras connected to my Pi and an external HDD for writing events captured by the cameras. I decided that ZoneMinder is the way to go. But all tutorials assume that one is an experienced RPi user, which I am not. At all.
Before I start listing the errors I get during failed installations, I would like to make sure that I am starting from the right OS.
What is the OS that suits my needs best please? I have installed NOOBS but not sure I did everything correct there, so I would like to troubleshoot that too if possible.
P.S. Ideally I see my board running a NAS, VPN server and email server along with zoneminder, but maybe I want too much from it???
