profile may not be available depending on the program
you use. Select the profile which is suitable for your
program.
Bit rate compression mode
Select
CBR
,
VBR
or
Adaptive rate control
.
If you want to keep the bit rate fixed, select
CBR
. If you
want to keep the image quality fixed, select
VBR
.
If you select
Adaptive rate control
, the bit rate is
automatically optimized for unstable network
connections or wireless networks with a lot of
interference.
Notes
• The frame rate or bit rate that is actually transmitted
may be different from the set values depending on
image size, scene, network environment.
• The
Adaptive rate control
cannot operate when the
Plug- in free viewer is being used.
• If you want to use the
Adaptive rate control
, set the
connection method in the live viewer to
Unicast
. If
you set
TCP
as a connection method, the adaptive rate
control will be disabled. For details, refer to
“Switching Transmission Mode” in “Operating the
Camera” on page 18.
Bit rate
When you set
Image codec
to
H.264
and set
Bit rate
compression mode
to
CBR
, the bit rate of the image
transmission for a line can be set.
When the bit rate is set to a high level, a high image
quality can be enjoyed.
Maximum bit rate limit
Enable the check box when
Bit rate compression mode
is set to
VBR
, to set the maximum value of the bit rate.
Max:
Set the maximum value of the bit rate when the
camera is operated with
VBR
.
Accept frame skip:
If you enable the checkbox, the
frame skip will be allowed for bit rate control.
Min, Max
Set the maximum and minimum bit rates that are
adjusted with the adaptive rate mode when
Bit rate
compression mode
is set to
Adaptive rate control
.
Image quality
If you set
Image codec
to
JPEG
, or
Bit rate
compression mode
to
VBR
when
Image codec
is set to
H.264
, the image quality setting will be enabled.
Selectable values are from
1
to
10
. When
10
is selected,
the best image quality is achieved.
Bandwidth control
Limits the network bandwidth for the JPEG image data
output from the camera when you set
Image codec
to
JPEG
.
Note
Audio may be interrupted depending on the selected
bandwidth. In this case, select a wider bandwidth. This
function is not available when the setting is set to
