H.264(1)/H.264(2)
[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)” or “H.264(2)”, 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)” and “H.264(2)”, H.264 images are viewable using other devices with each setting.
•
When “On” is selected for “H.264 transmission” in “H.264(1)” or “H.264(2)”, the transmission interval of JPEG images may sometimes become longer.
•
When “H.264” is selected for “Recording format”, it is impossible to transmit H.264 images with the settings for “H.264(2)”. In this case, the settings for “H.264(2)” are invalidated.
[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) *”.
•
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)*”.
Note
•
When “Frame rate” 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*
Note
•
When “Frame rate” 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.
[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*/ 8192kbps*/ Unlimited*
* The range of bit rates that can be configured for the H.264 bit rates differs depending on the “Image capture size”.
•
QVGA, VGA, 800x600, 320x180, 640x360: 64kbps - 4096kbps*
•
1920x1080, 1280x960, 1280x720: 256kbps* - 8192kbps*
“Unlimited*” is available only when “Frame rate” is selected for “Transmission priority”.
Note
•
When “8192kbps*” or “Unlimited*” is selected, the number of users who can access H.264 images will be limited to “1”. (Only a single user can access H.264 images.)
•
The H.264 bit rate is restricted by “Bandwidth control(bit rate)” on the [Network] tab on the “Network” page (→
17.1 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.
•
It is impossible to select “Unlimited*” for both “H.264(1)” and “H.264(2)”.
[Image quality]
Select the image quality of H.264 images from the following.
Low(Motion priority)/ Normal/ Fine(Image quality priority)
Note
•
When “Constant bit rate” or “Best effort” 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)” (→
17.1 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)
Enter the unicast port number (used to transmit images from the camera).
•
Available port number: 1024 - 50000 (Only even numbers are available.)
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.
[Smoother live video display on the browser (buffering)]
Perform settings to display camera images on the viewer software.
•
On: Images are temporarily stored on the computer and are displayed smoother.
•
Off: Images are displayed in real-time and are not stored on the computer.
IMPORTANT
•
If it appears that there is a delay in the images being displayed, select “Off”.
