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 16 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 68)
Refer to the operating instructions of the router in
use.
Multicast:
No concurrent access limitation for a cam-
era. Complete the entry field of "Multicast address",
"Multicast port" and "Multicast TTL/HOPLimit" when
transmitting MPEG-4 images with multicast.
Refer to "Operating Instructions" 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:
32004
[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:
33004
[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
Note:
Enter a multicast address after checking available
multicast address.
Available IPv6 address:
Multicast address starting
from "FF"
Default:
239.192.0.20
[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
[Multicast TTL/HOPLimit] *
2
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. In this case, refer to the network administra-
tor.
• 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".
*3: Images will not be transmitted for access using the
different IP address version set for "Multicast
address".
