[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/ 0.33s/ 0.5s/ 1s/ 2s/ 3s/ 4s/ 5s
Default: 3s
[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)" will
automatically be selected when transmitting images
from the camera. 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)" manually to transmit images
from the camera. It is possible to fix the port num-
ber of the router used for H.264 image transmission
via the Internet by setting "Unicast port (MANUAL)"
(☞ page 46). 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 6 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).

[Multicast address]*2
Enter the multicast IP address.
Images 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"

Important:
•WhentransmittinganH.264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.
*1 It is necessary to designate the unicast port number
when "Unicast port (MANUAL)" is selected for
"Transmission type".
*2 It is necessary to designate the multicast IP address
when "Multicast" is selected for "Transmission
type".
