[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.
•
Default: On
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.

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)*”.
•
Default: Frame rate
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*
•
Default: 30fps*
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)” is selected for “Image capture mode”.
[Burst tolerance level]

High/Middle/Low
•
Default: 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
•
Default: 24h
Note
•
This setting is only available when “Advanced VBR” is selected for “Transmission priority”.

[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
•
Default: 1s
[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.
