the image. They can be used to give better control of the bitrate by enhancing the encoding
quality of important regions (objects) and decreasing the encoding quality of less important
regions (background).
Eight encoder regions can be defined:

Privacy Masks

Privacy Masks block specific areas of a scene from being seen in the camera's field of view.
This can be useful when public spaces are in the coverage area or monitoring will be limited to
a particular zone.
Pattern
Select the color of the mask as it will appear in the live video: Auto, Black, Gray, White or
Custom color.
When Auto is selected, for one or more masks with a similar background, these will try to
blend with the surrounding color. If the backgrounds have different colors, the masks will
average between the colors.
A total of eight (8) masks can be in view at the same time.
