Video Stream
Define the maximum video stream time per session in seconds, minutes or hours. When the set time has expired, a new stream can be started by refreshing the page in the Web browser. For unlimited video stream time, set this value to 0. This setting is only applicable to Motion JPEG.
The frame rate allowed to each viewer can also be limited, to avoid bandwidth problems on the network.

Overlay/Mask Type

•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.
