Setting the Camera Image and Audio — Camera Menu
40
Bandwidth control (for JPEG only)
Limits the network bandwidth for the JPEG image data
output from the camera. Selectable bandwidths are as
follows:
0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 2.0, 3.0, 4.0 (Mbps), and
Unlimited
Note
Audio may be interrupted depending on the selected
bandwidth. In that case, select a wider bandwidth.
Bit rate (for MPEG4 only)
Set the bit rate of MPEG4 image transmission for a line.
Selectable values are as follows:
64, 128, 256, 384, 512, 768, 1024, 1536, 2048 (kbps)
Notes
• The actual frame rate and bit rate may be different
according to the image size, the shooting scene, or the
network condition.
• When
MPEG4
is selected, the image size is set to
640
× 480 (VGA)
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)
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 UDP
or multicast.
Unicast streaming
Specify the transmission port numbers of the 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
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.
Multicast streaming
Set whether the camera uses multicast streaming for
MPEG4 images or not. It reduces the transmission load
on the camera by making the computer of the same
segment network receive the same transmitting data.
Select
On
to allow and
Off
not to allow multicast
sending.
When you select
On
, set
Multicast address
,
Video port
number
and
Audio port number
properly.
