17 AXIS 221 - Video and Image Settings
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.
Test
To preview the image before saving, click Test. 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 Settings
Overlay image
Text, date and
time overlays
Text Overlay
These settings enable you to
place text at the top or bottom
of an image, e.g. date, time or
some other text.
Overlay/Mask Type
When using an image overlay,
select from the following
options the type to use:
• Uploaded image as overlay -
usually used to provide extra
information in the video
image.
• Configurable areas as privacy masks - up to 3 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.
