Note:
• When "Constant bit rate" or "Best effort" 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 H.264 images.
If using under a network environment with frequent
error occurrences, shorten the refresh interval for H.264
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 H.264 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 H.264 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 H.264 image transmission via the Internet
by setting "Unicast port (MANUAL)" (
☞
page 88).
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 H.264 images
with multicast.
Refer to page 7 for further information about the
maximum concurrent access number.
Default:
Unicast port (AUTO)
[Unicast port1(Image)]*
1
Enter the unicast port number (used to transmit images
from the camera).
Available port number:
1024 - 50000 (Only even num
-
bers are available.)
Default:
H.264(1): 32004
H.264(2): 32014
[Unicast port2(Audio)]*
1
Enter the unicast port number (used to transmit audio
from the camera).
Available port number:
1024 - 50000 (Only even num
-
bers are available.)
Default:
H.264(1): 33004
H.264(2): 33014
[Multicast address]*
2
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:
H.264(1): 239.192.0.20
H.264(2): 239.192.0.21
Note:
• Enter a multicast IP address after checking available
multicast address.
[Multicast port]*
2
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 unit, the port
number to be used will be the multicast port num-
ber plus "1000".
[Multicast TTL/HOPLimit]*
2
Enter a value for "Multicast TTL/HOPLimit".
Available value:
1-254
Default:
16
