■MPEG-4 setup
Click the [JPEG/MPEG-4] tab on the "Camera setup" page. (☞pages 20 and 21: How to display/operate the setup
menu)
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 35 for further information about the settings relating to JPEG images.
Refer to page 89 for how to configure settings to transmit MPEG-4 images via the Internet.
[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: ON
Note:
When "ON" is selected for "MPEG-4" transmission,
displaying of MPEG-4 images or JPEG images will
be available. However, the refresh interval (JPEG)
may be longer than the set value when displaying
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: 2048 kbps*
Note:
The MPEG-4 bit rate is synchronized with "Total bit
rate" on the [Network] tab of "Network setup" page
(☞page 68). For this reason, the bit rate may be
lower than the value when any 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: VGA
[Image quality]
Select the image quality of MPEG-4 images from the
following.
Fine/Normal/Low
Default: Normal
[Refresh interval (MPEG-4)]
Select an interval (I-frame interval; 1 - 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.
Default: 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)". (☞page 89)
Refer to the operating instructions of the router in
use.
