A customer claimed that he could not set the parameters for the "Secondary 2" video stream for an IPC camera 6525-Z30 as the "Secondary 2" video stream settings did not appear at all when going to Settings -> Video/Audio/Image -> Video Settings (as can be seen in the screenshot below):

The solution is to set the "Full frame rate" for "Primary, Secondary 1" video stream to 25Hz or below. Due to hardware limitations, when frame rate is set to 50/60 Hz, the "Secondary 2" stream cannot be set and it is not shown in the settings.
