20 AXIS 243SA - Video & image settings
Video Stream
The Maximum video stream time can be set as Unlimited, or set a maximum stream time
per session in seconds, minutes or hours. When the set time has expired, a new stream on
the Live View page can be started by refreshing the page in the web browser. Note that the
maximum video stream time does not apply to clients connecting via multicast.
To avoid bandwidth problems on the network, the frame rate allowed to each viewer can
also be limited. Select either Unlimited or define a maximum frame rate per viewer.
Test
For a preview of the image and overlay settings before saving, click Test. When you are
satisfied with the settings, click Save.
Video source settings
Select the physical connector the video source is connected to, BNC or Y/C.
• BNC (composite video) connects a standard video camera or other video equip-
ment
• Y/C (S-video) connects a Y/C (S-Video) camera or other video equipment
The video type can be converted from composite video to Y/C (S-Video) by using a Y/C to
BNC cable. See page 63 for more information. See also Switches & connectors, on page 8.
These settings also allow you to eliminate black borders surrounding the image, by making
Offset adjustments. See the online help for more information.
Advanced - MPEG-4 settings
Tools for adjusting the MPEG-4 settings and for controlling the video bit rate.
The MPEG-4 standard provides many different coding tools for various applications in
different situations. As most MPEG-4 clients do not support all these tools, it is usual to
instead define and use subsets for different clients or groups of clients. These settings allow
you to define the type of viewing client to use.
Adjusting the maximum bit rate and setting it to variable or constant is a good way of
controlling the bandwidth used by the MPEG-4 video stream.
For more information on these advanced settings, please see the online help.
