I think they mean something like widevine a la Netflix. Granted there are bypasses for some levels, but that could be a problem imo, iiuc that’s why there aren’t any alternate frontends for Netflix or HBO. I think that would also potentially mean issues playing YouTube in chromium or firefox on Linux if they used L1 (not sure what the current state of widevine on Linux is, last time I had Netflix I couldn’t watch on Linux and had to use my phone or Chromecast)
I’ve been happy with the tp link TV-IP324PI, it’s a Poe bullet cam with a simple web interface (I don’t think it requires JS, but at any rate you just need to log in once to set a password, make sure upnp is off, and adjust camera/encoding/fps/text overlay settings to your liking). There’s also the amcrest IP5M-B1186EW-28MM, another similar Poe bullet cam with night vision that works local only. I’ve used both for several years and I think they support onvif but I had no issues using the rtmp url with zoneminder
