Thanks for posting this. I contacted Vivotek and they fixed it remotely the same day - good support. The problem in my case (IP8335H) was that one of the first settings I changed was putting the power line frequency to 50Hz. The default fps setting is 30, which is not valid on 50Hz. So only switch the power line frequency after lowering the framerate. Annoying bug, but simple workaround.
