Some reolink cameras (B800 for sure) scramble the encoding to lock them to reolink NVRs. I used two of them with frigate by running neolink because fuck vendor lock in

I had problems with the 0.6.x series but 0.5.18 ran well enough. I abandoned those cams because they would occasionally switch to sending static to frigate and locking it down.
