Panasonic WV-SC384 Operating Instructions Manual page 55

[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/ 0.25s/ 0.33s/ 0.5s/ 1s/ 2s/ 3s/ 4s/ 5s
Default: 1s
[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 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 14 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 98). Refer to the operating instructions of the
router in use.
Multicast: Unlimited number of users can access a sin-
gle camera concurrently. Complete the entry field of
"Multicast address", "Multicast port" and "Multicast
TTL/HOPLimit" when transmitting MPEG-4 images
with multicast.
* Refer to page 7 for further information about the
maximum concurrent access number.
Default: Unicast port (AUTO)
1
[Unicast port1(Image)]*
Enter the unicast port number (used to transmit images
from the camera).
Available port number: 1024-50000 (Only even num-
bers are available.)
Default: M PEG-4(1): 32004
MPEG-4(2): 32014
[Unicast port2(Audio)]*
Enter the unicast port number (used to transmit audio
from the camera).
Available port number: 1024-50000 (Only even num-
bers are available.)
Default: M PEG-4(1): 33004
MPEG-4(2): 33014
2
[Multicast address]*
Enter the multicast IP address.
Images and audio will be transmitted to the designated
IP address.
Available IPv4 address: 224.0.0.0 - 239.255.255.255
Available IPv6 address: Multicast address starting with
"FF"
Default: M PEG-4(1): 239.192.0.20
MPEG-4(2): 239.192.0.21
Note:
• Enter a multicast IP address after checking available
multicast address.
2
[Multicast port]*
Enter the multicast port number (used to transmit
images from the camera).
Available port number: 1024 - 50000 (Only even num-
bers are available.)
Default: 37004
Note:
• When audio is transmitted from the camera, the port
number to be used will be the multicast port num-
ber plus "1000".
[Multicast TTL/HOPLimit]*
Enter the multicast TTL/HOPLimit value.
Available value: 1 - 254
Default: 16
Important:
• When transmitting an MPEG-4 image via a network,
the transmitted image sometimes may not be dis-
played depending on the settings of a proxy server
or a firewall. In this case, refer to the network
administrator.
• When two or more network interface cards are
installed on the PC in use, the network interface
card(s) not used for receiving images should be
invalidated when displaying images using the multi-
cast port.
