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 8 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 unit.
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)". Refer to the oper-
ating instructions of the router in use.
Multicast:
No concurrent access limitation for a unit.
Refer to page 4 for further information about the maxi-
mum concurrent access number.
Default setting:
Unicast port (AUTO)
Important:
When "Multicast" is selected, set the value of "Total
bit rate" greater than the total value of "Max bit rate
(per 1 client)" of all the channels.
[Max number of MPEG-4 clients]
Select the number of users to transmit MPEG-4 images
at a time. Up to 8 users are available.
* MPEG-4 images are not transmitted from each
channel to more users than the maximum number.
Available value:
1 - 8
Default setting:
4
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 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.
[Unicast port1 (Image)]
Enter the unicast port number (used to transmit images
from the camera).
Available value:
1024 - 50000 (Only even numbers are
available.)
Default setting:
CH1: 32004
CH2: 32006
CH3: 32008
CH4: 32010
[Unicast port2 (Audio)]
Enter the unicast port number (used to transmit audio
from the unit).
Available value:
1024 - 50000 (Only even numbers are
available.)
Default setting:
33004
[Multicast address]
Enter the multicast IP address.
Images and audio will be transmitted to the designated
IP address.
Available value:
224.0.0.0 - 239.255.255.255
Default setting:
239.192.0.20
[Multicast port]
Enter the multicast port number (used to transmit
MPEG-4 images from the unit).
Available value:
1024 - 50000 (Only even numbers are
available.)
Default setting:
CH1: 37004
CH2: 37006
CH3: 37008
CH4: 37010
[Multicast TTL]
Enter the multicast TTL value.
Available value:
1 - 254
Default setting:
16
■
Calculation of refresh interval (JPEG)
It is possible to calculate an interval to refresh the dis-
played JPEG image that can be transmitted to the max
number of users accessing.
Calculated values are approximate. Refresh interval
changes depending on the settings or the network sta-
tus.
[Number of JPEG clients when connecting with max
number of MPEG-4 clients]
The number of JPEG clients of each channel that can
connect when the number of accessing MPEG-4 clients
is maximum is displayed.
[Number of JPEG monitoring clients]
Select the number of users of each channel to monitor
JPEG images on the browser.
