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 browser. For unlimited video stream time,
select the Unlimited radio button option. Note that the maximum video stream time does not apply to
clients connecting via multicast.
The fram e rate allowed to each viewer can also be limited to avoid bandwidth problems on the network. To
allow the highest available frame rate, select the Unlimited radio button option.
For a preview of the image click Test. When satisfied with the settings, click Save. Note that the preview
image will be in JPEG format, even though the settings are valid both for Motion JPEG and MPEG-4.
Overlay/Mask
Overlay/Mask Settings
When using an image overlay, select
from the following options:
• Uploaded image as overlay - usually
used to provide extra information in
the video image.
• Configurable a reas as privacy masks
- up to three 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. After you choose one of these options further options are displayed for
the selected type. See the online help for further information.
