Some users in those mention getting RTSP to work in Blue Iris, and one thing I see mentioned more than once is making sure that the camera is set to use RTSP and not RTSPS. Comparing the screenshot in this post…
…to yours, I see at least three differences, though I don’t use Blue Iris and don’t know what effect each of these might have:
You have Discovery/ONFIV port set for 554; the other screenshot shows 80.
You have Use RTSP/stream timecode selected; the other screenshot shows it deselected.
You have Decoder compatibility modedeselected; the other screenshot shows it selected.
