■ MPEG-4 setup
Configure the settings relating to MPEG-4 image such as "Max bit rate (per 1 client)", "Image capture size", "Image
quality", etc. in this section. Refer to page 21 for further information about the settings relating to JPEG images.
[MPEG-4 transmission]
Select "ON" or "OFF" to determine whether or not to
transmit MPEG-4 images.
ON: Transmits MPEG-4 images.
OFF: Does not transmit MPEG-4 images.
Default setting: ON
Note:
When "ON" is selected for "MPEG-4 transmission",
displaying rather of MPEG-4 image or JPEG image
will be available. However, the refresh interval
(JPEG) may be longer than the set value when dis-
playing JPEG images.
[Max bit rate (per 1 client)*]
Select a MPEG-4 bit rate per a client from the following.
64 kbps/128 kbps */256 kbps */512 kbps */1024 kbps */
1536 kbps */2048 kbps */3072 kbps */4096 kbps *
Default setting: 2048 kbps *
Note:
The MPEG-4 bit rate is synchronized with "Total bit
rate" on the [Network] tab of "Network setup" page.
(☞ page 39) For this reason, the bit rate may be
lower than the value when the setting value with an
asterisk (*) on the right is selected.
[Image capture size]
Select "QVGA" or "VGA" for the image capture size of
MPEG-4 images.
Default setting: VGA
22
[Image quality]
Select image quality of MPEG-4 images from the follow-
ing.
Fine/Normal/Low
Default setting: Normal
[Refresh interval (MPEG-4)]
Select an interval (I-frame interval; 1 - 5 seconds) to
refresh the displayed MPEG-4 images.
If using under the network environment with frequent
error occurrences, shorten the refresh interval for
MPEG-4 to diminish image distortions. However, the
refresh interval (MPEG-4) may be longer than the set
value when displaying JPEG images.
Default setting: 3 sec
[Transmission type]
Select a MPEG-4 transmission type from the following.
Unicast port (AUTO): Up to 8 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 camera.
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)".
Unicast port (MANUAL): Up to 8 users can access a
single camera concurrently. It is necessary to select
"Unicast port1 (Image)" and "Unicast port2 (Audio)"
manually to transmit images and audio from the
camera.
It is possible to fix the port number of the router used
for MPEG-4 image transmission via the Internet by
setting "Unicast port (MANUAL)". Refer to the oper-
ating instructions of the router in use.
Multicast: No concurrent access limitation for a cam-
era.
* Refer to page 4 for further information about the
maximum concurrent access number.
Default setting: Unicast port (AUTO)
