The frame rate allowed to each viewer can also be limited, to avoid bandwidth problems on the network.

•Configurable areas as privacy masks - up to 3
black areas are used to conceal parts of the video image.
The difference between an overlay and a privacy mask is that a privacy mask cannot be bypassed by accessing the video stream with the help of the AXIS HTTP API, whereas an overlay can.
Selecting the overlay/mask type will display further settings available for the selected type. See the online help for further information.
