Frankly, once you get more than just a few cameras, being able to edit a config file is so much better than having to click through settings for literally hours like with Shinobi or Motioneye.
I’ve personally been quite pleased with the combination of Frigate and some Amcrest POE cameras. Just make sure the cameras you are getting support RTSP though and you should be able to use them with Frigate.
Also make sure you block the cameras from reaching the public internet using your firewall, and only make them reachable from your Frigate host. Personally I use a VLAN with no internet access and enforce tagging at the switch level (i.e. don’t trust the cameras to maintain their own VLAN) settings.
