Configure the settings relating to MPEG-4 image [JPEG/MPEG-4]
Click the [JPEG/MPEG-4] tab on the "Camera setup" page. (☞ page 23)
Configure the settings such as "Max bit rate (per 1 client)", "Image capture size" and "Image quality" on this page.
Refer to page 23 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: ON
[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 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: VGA
[Image quality]
Select image quality of MPEG-4 images from the follow-
ing.
Fine/Normal/Low
Default: Normal
[Refresh interval (MPEG-4)]
Select an interval (1 - 5 seconds) to refresh the dis-
played MPEG-4 images.
If using the network environment with frequent error
occurrences, images can be displayed quickly, and it is
possible to diminish image distortions by setting a short-
er refresh interval. However, the refresh interval
(MPEG-4) may be longer than the set value.
Default: 3 sec
[Transmission type]
Select a MPEG-4 transmission type from the following.
Unicast: Up to 8 users can access a single camera
concurrently.
Multicast: No concurrent access limitation for a cam-
era.
Default: Unicast
[Multicast address]
Enter the multicast IP address.
Available range: 224.0.0.0 - 239.255.255.255
Default: 239.192.0.20
[Multicast port]
Enter the multicast port number (used to transmit
MPEG-4 images from the camera).
Available port number: 1024 - 50000 (Only even num-
bers are available.)
Default: 37004
[Multicast TTL]
Enter the multicast TTL value.
Available value: 1 - 254
Default: 16
Important:
• Depending on the PC in use for monitoring, the mul-
ticast port number may be already in use. In this
case, it may be impossible to monitor images.
Change the multicast port number.
• When transmitting MPEG-4 image via a network, the
transmitted image sometimes may not be displayed.
In this case, refer to the network administrator.
• When two network interface cards or more are
installed on the PC in use, the network interface
card(s) not used for receiving images should be
invalidated when displaying MPEG-4 images using
the multicast port.
