Note:
•When "Constant bit rate" is selected for "Recording priority", this setting is available.
[Refresh interval]
Select an interval
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).
Available port number: 1024 - 50000 (Only even num- bers are available.)
Default: H.264(1): 32004 H.264(2): 32014
[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"
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
[Multicast TTL/HOPLimit]*2
Enter the multicast TTL/HOPLimit value.
Available value: 1 - 254
Default: 16
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".
