rotate 180 / flip upside-down camera image

[Cold-Lemonade]

I have a Dahua PTZ1A225-HNR-XA camera. The problem is that the camera image is upside down. I am hoping someone here might know how to fix this.

I've tried to flip (or 180-degrees rotate) the image by changing the appropriate setting in the camera's GUI. Unfortunately, there doesn't seem to be a setting that I can change through the GUI. The closest seems to be "View Angle Mode" which is set to "Auto" in a drop-down menu with no other options.

I'm guessing there must be a way to flip/rotate the image using the Dahua HTTP API by issuing a curl command from the command line. The relevant setting seems to be VideoImageControl[0].Flip=true. But I think this is being overridden by the camera because the VideoImageControl[0].FlipMode=Auto. Unfortunately, I don't know what the other FlipMode settings are. I've tried 0, 1, 2, and Manual and Flip to no avail.

Any suggestions on what to do?

The option is there on my camera under conditions -> flip

Thanks. But that option does not exist in my camera's GUI. But I found it... I had to select "inverted" under "installed mode" in the "General -> System" tab.
