18 AXIS 223M - Video and Image Settings
When you check the Widescreen resolutions (16:9) option under Image Appearance, all
the currently open video streams are stopped and the resolutions for this format are
displayed in the drop-down list. Open video streams are also stopped when this box is
unchecked and the format switches to 4:3. Please see the online help for further
information on these settings.
Text overlay settings - The date, time, and user defined text can be included on one line,
either on the top or bottom of the video image.
It is also possible to set how the text and text background are displayed. You can set the
text to be either black or white, and the text background can also be set to black, white,
semi-transparent, or transparent.
Please see the online help for further information on these 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
Overlay/Mask type
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 areas as pri-
vacy mask - 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.
