Note:
• When "On" is selected, only "Unicast port (AUTO)"
will be available for "Transmission type".
• When "On" is selected, it may take seconds to start
displaying MPEG-4 images.
• When "On" is selected, MPEG-4 images may not be
displayed depending on the number of the concur-
rent access users and audio data availability, etc.
• When "On" is selected, only IPv4 access is avail
-
able.
[Image capture size]
Select "QVGA" or "VGA" for the image capture size of
MPEG-4 images.
Default:
MPEG-4(1): VGA
MPEG-4(2): VGA
[Transmission priority]
Select a transmission priority for MPEG-4 images from
the following.
Constant bit rate:
MPEG-4 images will be transmitted
with the bit rate selected for "Max bit rate (per cli-
ent)*".
Frame rate:
MPEG-4 images will be transmitted with
the frame rate selected for "Frame rate*".
Best effort:
In accordance with the network bandwidth,
MPEG-4 images will be transmitted with the bit rate
varying between the maximum and minimum bit
rates that are set for "Max bit rate (per client)*".
Default:
Frame rate
Note:
• When "Frame rate" is set for "Transmission priority",
number of users who can access the camera may
be limited.
[Frame rate*]
Select a frame rate for MPEG-4 images from the follow-
ing.
1fps/ 3fps/ 5fps*/ 7.5fps*/ 10fps*/ 12 fps (PAL model)*/
15fps*/ 20fps*/ 30fps*
Default:
30fps*
Note:
• When "Frame rate" is selected for "Transmission
priority", this setting is available.
• "Frame rate*" is restricted by "Max bit rate (per cli
-
ent)*". For this reason, the frame rate may be lower
than the specified value when any value marked
with an asterisk (*) is selected.
[Max bit rate (per client)*]
Select a MPEG-4 bit rate per a client from the following.
When "Best effort" is selected for "Transmission prior-
ity", set the maximum and minimum bit rates.
64kbps/ 128kbps*/ 256kbps*/ 384kbps*/ 512kbps*/
768kbps*/ 1024kbps*/ 1536kbps*/ 2048kbps*/
3072kbps*/ 4096kbps*/ Unlimited*
Default:
MPEG-4(1): 2048kbps*
MPEG-4(2): 2048kbps*
* "Unlimited*" is available only when "Frame rate" is
selected for "Transmission priority".
Note:
• The MPEG-4 bit rate is restricted by "Bandwidth
control (bit rate)" on the [Network] tab on the
"Network" page (
☞
page 87). For this reason, the bit
rate may be lower than the value when any value
with an asterisk (*) on the right is selected.
• When "Unlimited*" is selected, the number of users
who can access MPEG-4 images will be limited to
"1".
(Only a single user can access MPEG-4images.)
• It is impossible to select "Unlimited*" for both
"MPEG-4(1)" and "MPEG-4(2)".
[Image quality]
Select the image quality of MPEG-4 images from the
following.
Low(Motion priority)/ Normal/ Fine(Image quality prior-
ity)
Default:
Normal
Note:
• When "Constant bit rate" or "Best effort" is selected
for "Transmission priority", this setting is available.
