Table 5-3 Compression Settings
Description
4CIF is the highest resolution and CIF is the lowest resolution.
The frame rate that is displayed per second. For NTSC, select from 1 fps (lowest)
to 30 fps (highest). For PAL, select from 1 fps (lowest) to 25 fps (highest).
Allows you to set the maximum bit rate and/or target rate value, based on priority
mode settings. This value is the threshold that you do not want the bit rate to
exceed.
To enable this field ...

The Picture Quality field

When Quality is selected as the Priority, select the Picture Quality as Good
(lowest visual quality), Better, or Best (highest visual quality).
Enter the Target Bit Rate in kbps (kilobits per second) which represents the
amount of data processed per second.
Select the GOP (Group of pictures) number from 1 to 100.
3. When you are satisfied with your settings—that is, that the image quality and
bandwidth usage meets your requirements—click Apply to save your settings.
Adjustments in your compression settings are captured in the statistics. As you make
adjustments, the Statistics field acts as a visual reminder of how your settings affect
the bit rate, frame rate, and bandwidth usage.
To achieve this ...
If the target bit rate exceeds the maximum bit rate
value, the camera adjusts the picture quality first
and then, if necessary, drops frames to meet the
maximum bit rate value.
Set the Maximum Bit Rate—limit the data transfer
speed—from 1.3~2.0 X Target Bit Rate. As the
target bit rate exceeds the maximum bit rate value,
the camera reduces the bit rate by adjusting the
frames dynamically to stay below the threshold
that you set.
