We would need to see your present settings to assist. Just one thought - try ticking "Decoder compatibility mode" in the BI5 settings for that camera and see if that helps. hello, here is my setting in the Amcrest NVR that is working great https://drive.google.com/file/d/1a9syGR1fcXEfr3HI...

this is my indoor camera with RTSP and it works great with an Amcrest NVR. https://www.amazon.com/gp/product/B08571VZ3Q/

strangely, in BI, the cam keeps freezing or disconnected. can someone please share a screenshot of your BI settings that is working for you?
