Image size [1280 × 1024]
SNC-CH240/CH280/DH240/DH240T/DH280
When image size of image 1 is “1920 × 1080”; the
image size of image 2 is “640 × 480”
SNC-CH240/CH280/DH240/DH240T/DH280
When image size of image 1 is “1920 × 1440”; the
image size of image 2 is “640 × 480”
Bit rate
Set the bit rate of MPEG4 or H.264 image transmission
for a line. When the bit rate is set to a high level, better
image quality can be enjoyed.
Selectable bit rates are as follows:
64, 128, 256, 384, 512, 768, 1024, 1536, 2048, 3072,
4096, 5120, 6144, 7168, 8192 (kbps)
I-picture interval
Set the I-picture insertion interval.
Adaptive rate control
This function adjusts the frame rate and the bit rate
automatically so that the camera plays back a smooth
image to suit the connected computer environment. If
On
is selected, the MPEG4 or H.264 image rate is
automatically adjusted.
Notes
• The actual frame rate and bit rate may be different
depending on the image size, shooting scene, or
network condition.
• When
Adaptive rate control
is set to
On
, the actual
frame rate and bit rate change within the range that
does not exceed the values set in
Frame rate
and
Bit
rate
.
Image quality
Set the JPEG image quality.
Selectable values are from
Level 1
to
Level 10
.
When
Level 10
is selected, the best image quality is
achieved.
Bandwidth control
Limits the network bandwidth for the JPEG image data
output from the camera.
