20AXIS 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.
