Adaptive rate control (for MPEG4 and H.264
only)
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
according to the image size, the shooting scene, or the
network condition.
• When
Adaptive rate control
is set to
On
, the
maximum transmission rate will be the values set in
Frame rate
and
Bit rate
.
• When
H.264
is selected and the image size is set to
640 × 480 (VGA)
or
384 × 288
, the frame rate used by
the camera to transmit the image will be as follows:
SNC-CS50N: 10 fps or less
SNC-CS50P: 8 fps or less
• When
MPEG4
is selected, the image size is set to
640
× 480 (VGA)
or
384 × 288
and the frame rate is set to
30 fps
.
The frame rate may be decreased when the bit rate is
more than 512 kbps or while the object detection
function is operating.
• When the camera operation mode is set to
Dual codec
and the image size is set to
640 × 480 (VGA)
or
384 ×
288
in
MPEG4 setting
, the maximum frame rate at
which the camera can transmit data will be 20 fps.
• When the camera operation mode is set to
Dual codec
,
the actual values set in
MPEG4 setting
and
JPEG
setting
may not be obtained, due to the limitation in
the capacity to manage two video codecs
simultaneously. Use the following table as a guide for
the settings.

Streaming Tab
Use this tab to set the items for the transmission by
unicast or multicast.
Unicast streaming
Specify the transmission port numbers of the MPEG4 or
H.264 video data and audio data to be used when
UDP
(Unicast)
is selected with
in the main viewer.
Video port number
Specify the transmission port number of the MPEG4 or
H.264 video data. It is initially set to 50000. Specify an
even number from 1024 to 65534. Two port numbers
(the number specified here and an odd number with 1
added to the specified number) are actually used for
video data communication and control.
Audio port number
Specify the transmission port number of the audio data.
It is initially set to 50002. Specify an even number from
1024 to 65534. Two port numbers (the number specified
here and an odd number with 1 added to the specified
number) are actually used for audio data communication
and control.
Note
Specify different numbers for the video port number and
the audio port number.
