I have Blue Iris 5.8.9.6 connected to a rstp feed from a hikvision cctv and I have one camera that zooms in and out at regular intervals. I have checked most/all settings that I am aware of and cannot find anything that would cause that. I also deleted and re-added the feed. Any ideas as to what that could be or settings that I am not aware of?

Thank you.

Did this start after a recent update?
Have you tried going back to a prior version?
Does the camera itself have a zoom function, if so could it be malfunctioning?
