• When "On" is selected, only IPv4 access is avail-
able.
• When "On" is selected for either "MPEG-4(1)" or
"MPEG-4(2)", only "Off" and "Mic input" are available
for "Audio transmission/reception".
• When "On" is selected for either "MPEG-4(1)" or
"MPEG-4(2)", the maximum concurrent access num-
ber is equal to or less than 10 users.
[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 "Constant bit rate" or "Frame rate" for the MPEG-
4 transmission mode.
Constant bit rate: MPEG-4 images will be transmitted
with the bit rate selected for "Max bit rate (per
client) *".
Frame rate: MPEG-4 images will be transmitted with
the frame rate selected for "Frame rate".
Default: Constant bit rate
Note:
When "Frame rate" is set for "Transmission priority",
number of users who can access the camera may
be limited more (may become less than 10).
[Frame rate]
Select a frame rate for MPEG-4 images from the follow-
ing.
1fps/3fps/5fps */7.5fps */10fps */15fps */20fps */30fps *
Default: 30fps *
Note:
• When "Frame rate" is selected for "Transmission pri-
ority", this setting is available.
• "Frame rate" is synchronized with "Max bit rate (per
client)*". 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.
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 synchronized with
"Bandwidth control(bit rate)" on the [Network] tab of
"Network" page (☞ page 73). 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-4
images.)
• 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.
Fine/Normal/Low
Default: Normal
Note:
• When "Constant bit rate" is selected for
"Transmission priority", this setting is available.
[Refresh interval]
Select an interval (I-frame interval; 0.2 - 5 seconds) to
refresh the displayed MPEG-4 images.
If using under a network environment with frequent error
occurrences, shorten the refresh interval for MPEG-4 to
diminish image distortions. However, the refresh interval
may be longer than the set value.
0.2s/0.33s/0.5s/1s/2s/3s/4s/5s
Default: 3s
[Transmission type]
Select the transmission type of MPEG-4 images from
the following.
Unicast port (AUTO): Up to 14 users can access a sin-
gle camera concurrently. "Unicast port1(Image)" and
"Unicast port2 (Audio)" will automatically be selected
when transmitting images and audio from the cam-
era.
When it is unnecessary to fix the port number for
MPEG-4 image transmission such as when using in
a particular LAN environment, it is recommended to
select "Unicast port (AUTO)".
