Thanks. First i was after TP-Link, because somebody i know as a versatile tech started using them and was satisfied. He's not much of a IT-security guy, so there's that. TPL abandoned RTSP in their newer models, and there are some quirks to become aware of to be able to choose a good model. Cloud recording would be a no-go, i also want to have remote access, but only through a tunnel/forward on my router's firewall using some dynamic dns service. No fancy cloud app with registering at the manufacturer needed (nor wanted).
EDIT: I wonder if this dip is more or less over...
If you have ONVIF but need RTSP, I found a handy app called
GO2RTSP which does some translations. It's a bit opaque but fairly straightforward.
