Audio & Video Settings
Video
The AXIS 250S provides the connection for a single analog camera (or other video source),
on either the BNC connector or the S-Video connector. Ensure that the camera is correctly
connected and powered up before attempting configuration.
•
Resolution
- the video resolutions available are QCIF, CIF, 2CIF and 4CIF. The exact resolutions
will depend on the type of video source being used, PAL or NTSC. See also
Technical Specifica-
tions,
on page 55.
•
Color
- Select either Color or Black & White. Black & White will provide sharper images at a
lower bandwidth than Color.
•
Quality level
- This setting determines the quality of the video stream, which also affects the
amount of bandwidth used. 1 is the lowest level and 7 the highest.
•
Physical connector
- Select the input the video source is connected to:
•
BNC
(composite video) - connects a standard video camera or other video source.
•
Y/C (S-video)
- connects an s-video camera or other video equipment.
•
Source modulation
- The AXIS 250S supports both of today's common video modulation stan-
dards. Select the correct standard from the drop-down list; PAL - the dominant standard in
Europe, or NTSC - the common standard in the United States.
There is also a check box “Include time.” which when checked includes the time and date in
the video stream.
Advanced Settings
The advanced settings allow the structure of the MPEG-2 video stream to be modified. The
GOP
(Group of Pictures) can take 3 forms -
IBBP
,
IBP
and
IP
. These forms describe the type
of pictures included in the stream and also their internal order. An I-picture is a complete
image, a P-image is the predicted difference between this image and a preceding I or
P-picture, and a B-picture is a comparison with both earlier and later pictures.
