Configuring the Compression Settings
1. On the Compression Settings tab, in the Statistics area, select the Received check
box to receive in real time the bit rate and frame rates for the current image.
Deselecting the check box disables the refresh rate.
Note The Received check box is disabled by default. When you log out, this check
box reverts to the disabled state.
2. Use Table 4-3 to set up the video compression.

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).
Priority Quality, Bit Rate 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.
Compression
Ratio
Minimum, Low,
Medium, High,
Maximum
When Quality is selected as the Priority, select the Compression Ratio.
Minimum is the highest visual quality; Maximum is the lowest visual quality.
Target Bit
Rate (kbps)
400 – 5000 kbps Enter the Target Bit Rate in kbps (kilobits per second) which represents the
amount of data processed per second.
GOP (No. of
Frames)
1– 60 Select the GOP (Group of pictures) number from 1 to 100. (Not available on the
Secondary Stream.)

Maximum Bit Rate
The Target Bit Rate field
is grayed out.
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.

Target Bit Rate and
Maximum Bit Rate
The Picture Quality field
is grayed out.
Set the Maximum Bit Rate—limit the data transfer
speed—from 400 ~ 5000 kbps. 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.
