I have mounted my camera upside down, how do I flip/mirror the image?

Step 1: Login to camera web UI, and Click icon.
Step 2: Select Setting -> Camera Setting -> Image and Audio Setting, then it will be under Image & Audio item:


 
Step 3: Enable both Mirror and Flip:

Note:
1.    Mirror: This will mirror the image horizontally
2.    Flip: This will flip the image vertically.
