H.264(1)/H.264(2)/H.264(3)/H.264(4)
[H.264 transmission]
Select “On” or “Off” to determine whether or not to transmit H.264 images.
•
On: Transmits H.264 images.
•
Off: Does not transmit H.264 images.
Note
•
When “On” is selected for “H.264 transmission” in “H.264(1)”, “H.264(2)”, “H.264(3)”, or “H.264(4)” displaying of H.264 images or JPEG images on the “Live” page will become available.
•
When “On” is selected for “H.264 transmission” in “H.264(1)”, “H.264(2)”, “H.264(3)”, or “H.264(4)”, the transmission interval of JPEG images may sometimes become longer.
[Internet mode (over HTTP)]
Select “On” when transmitting H.264 images via the Internet. It is possible to transmit H.264 images without changing the broadband router settings configured for JPEG image transmission.
•
On: H.264 images and audio will be transmitted using the HTTP port. Refer to
[HTTP port] for further information about the HTTP port number settings.
•
Off: H.264 images and audio will be transmitted using the UDP port.
Note
•
When “On” is selected, only “Unicast port (AUTO)” will be available for “Transmission type”.
•
When “On” is selected, it may take time to start displaying H.264 images.
•
When “On” is selected, H.264 images may not be displayed depending on the number of the concurrent access user and audio data availability, etc.
•
When “On” is selected, only IPv4 access is available.

[Transmission priority]
Select a transmission priority for H.264 images from the following.
•
Constant bit rate: H.264 images will be transmitted with the bit rate selected for “Max bit rate (per client) *”.
•
VBR: H.264 images will be transmitted with the frame rate selected for “Frame rate*” while maintaining the image quality level selected in “Image quality”. H.264 images will be transmitted with the bit rate kept within the maximum bit rate that is set for “Max bit rate (per client)*”. The image quality is fixed, and the recording capacity changes according to the “Image quality” setting and conditions of the subject. When calculation of recording capacity is needed in advance, use “Advanced VBR”.
•
Frame rate: H.264 images will be transmitted with the frame rate selected for “Frame rate*”.
•
Best effort: In accordance with the network bandwidth, H.264 images will be transmitted with the bit rate varying between the maximum and minimum bit rates that are set for “Max bit rate (per client)*”.
•
Advanced VBR: H.264 images are transmitted at the frame rate specified for “Frame rate*” while the image quality is controlled so that the average transmission rate during the period specified for “Control time period” becomes the bit rate selected for “Max bit rate (per client)*”.
Note
•
When “Frame rate” or “Advanced VBR” is selected for “Transmission priority”, number of users who can access the camera may be limited more (may become less than 10).
[Frame rate*]
Select a frame rate for H.264 images from the following.
1fps/ 3fps/ 5fps*/ 7.5fps*/ 10fps*/ 12fps*/ 15fps*/ 20fps*/ 30fps*/60fps*
Note
•
When “Frame rate”, “Advanced VBR”, or “VBR” is selected for “Transmission priority”, this setting is available.
•
“Frame rate*” is restricted by “Max bit rate (per client)*”. For this reason, the frame rate may be lower than the specified value when any value marked with an asterisk (*) is selected. When “VBR” is selected for “Transmission priority”, depending on the settings of “Max bit rate (per client)*” and “Image quality”, transmission of images may periodically be paused. Check the transmission of images after changing settings.
•
H.264(1) will be fixed to 60fps when “2 mega pixel [16:9](60fps mode)” or “1.3 mega pixel [16:9](60fps mode)” is selected for “Image capture mode”.
[Burst tolerance level]
Select how much the bit rate can exceed “Max bit rate (per client)*” by from the following.
High/Middle/Low
Note
•
This setting is only available when “Advanced VBR” is selected for “Transmission priority”.
[Control time period]
Select the time period that the bit rate will be controlled for from the following. Images are transmitted so that the average transmission rate during the selected period becomes the bit rate selected for “Max bit rate (per client)*”.
1h/6h/24h/1week
Note
•
This setting is only available when “Advanced VBR” is selected for “Transmission priority”.
[Max bit rate (per client)*]
Select a H.264 bit rate per a client from the following. When “Best effort” is selected for “Transmission priority”, set the maximum and minimum bit rates.
64kbps/ 128kbps*/ 256kbps*/ 384kbps*/ 512kbps*/ 768kbps*/ 1024kbps*/ 1536kbps*/ 2048kbps*/ 3072kbps*/ 4096kbps*/ 6144kbps*/ 8192kbps*/ 10240kbps*/ 12288kbps*/ 14336kbps*/ 16384kbps*/ 20480kbps*/24576kbps*/ 30720kbps*/ 40960kbps*
•
Default:
–
H.264(1): 4096kbps*

/ 2048kbps*

* The range of bit rates that can be configured for H.264 bit rates differs depending on the “Transmission priority” and “Image capture size”.
When “Constant bit rate”, “Frame rate”, “Advanced VBR”, or “Best effort” is selected for “Transmission priority”
•
160x120 and 160x90: 64kbps - 2048kbps*

•
2048x1536: 1024kbps* - 40960kbps*
Note
•
The H.264 bit rate is restricted by “Bandwidth control(bit rate)” on the [Network] tab on the “Network” page (→
16.1 Configure the network settings [Network]). For this reason, the bit rate may be lower than the value when any value with an asterisk (*) on the right is selected.
[Image quality]
Select the image quality of H.264 images from the following.
•
When “Transmission priority” is set to “Constant bit rate” or “Best effort”: Low(Motion priority)/ Normal/ Fine(Image quality priority)
•
VBR: 0 Super fine/ 1 Fine/ 2/ 3/ 4/ 5 Normal/ 6/ 7/ 8/ 9 Low
Note
•
When “Constant bit rate”, “Best effort”, or “VBR” 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
[Transmission type]
Select the transmission type of H.264 images from the following.
•
Unicast port (AUTO): Up to 14 users can access a single camera concurrently. “Unicast port1(Image)” and “Unicast port2(Audio)” will automatically be selected when transmitting images and audio 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)” 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)” (→
16.1 Configure the network settings [Network]). Refer to the operating instructions of the router in use.
•
Multicast: Unlimited number of users can access a single camera concurrently. Complete the entry field of “Multicast address”, “Multicast port” and “Multicast TTL/HOPLimit” when transmitting H.264 images with multicast. Refer to
1.1 Monitor images from a single camera for further information about the maximum concurrent access number.
•
Default: Unicast port (AUTO)
[Unicast port1(Image)]
Enter the unicast port number (used to transmit images from the camera).
•
Available port number: 1024 - 50000 (Only even numbers are available.)
[Unicast port2(Audio)]
Enter the unicast port number (used to transmit audio from the camera).
•
Available port number: 1024 - 50000 (Only even numbers are available.)
[Multicast address]
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”
Note
•
Enter a multicast IP address after checking available multicast address.
[Multicast port]
Enter the multicast port number (used to transmit images from the camera).
•
Available port number: 1024 - 50000 (Only even numbers are available.)
Note
•
When audio is transmitted from the unit, the port number to be used will be the multicast port number plus “1000”.
[Multicast TTL/HOPLimit]
Enter a value for “Multicast TTL/HOPLimit”.
IMPORTANT
•
When transmitting an H.264 image via a network, the transmitted image sometimes may not be displayed 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 multicast port.
