If you turn the MIRROR function on, the image will be flipped. It is like the image in
the mirror. The flip direction can be set to OFF, LEFT/RIGHT, UP/DOWN or CENTER.

WDR (Wide Dynamic Range)
The wide dynamic range (WDR) function helps the camera provide clear images even
under back light circumstances. When there are both very bright and very dark areas
simultaneously in the field of view, WDR balances the brightness level of the whole
image and provide clear images with details.
You can enable or disable the WDR function as shown in Figure 6-33. The wide
dynamic level ranges from 0 to 100.
