Constant bit rate: H.265 images will be transmitted with the bit rate selected for “Max bit rate (per client)*”.
VBR: H.265 images will be transmitted with the frame rate selected for “Frame rate*” while maintaining the image quality level selected in “Image quality”. In this case, images will be transmitted with the bit rate kept within the maximum bit rate that is set for “Max bit rate (per client)*”. The recording capacity changes according to the “Image quality” setting and conditions of the subject.
Frame rate: H.265 images will be transmitted with the frame rate selected for “Frame rate*”.
Best effort: In accordance with the network bandwidth, H.265 images will be transmitted with the maximum bit rates that are set for “Max bit rate (per client)*”.
Default: VBR
Note
When “Frame rate” is set for “Transmission priority”, number of users who can access the camera may be limited.
[Frame rate*]
Select a frame rate from the following.
When 30fps mode is selected for [Image capture mode]:
1fps/ 3fps/ 5fps*/ 7.5fps*/ 10fps*/ 12fps*/ 15fps*/ 20fps*/ 30fps*
When 25fps mode is selected for [Image capture mode]:
1fps/ 3.1fps/ 4.2fps*/ 6.25fps*/ 8.3fps*/ 12.5fps*/ 20fps*/ 25fps*
Default: Stream(1): 30fps*, Stream(2) and Stream(3): 15fps*
Note
If “On” is selected for “Stream(2)” or “Stream(3)”, the maximum frame rate changes as follows depending on the setting of “Image capture mode”:
16:9 (30fps mode)/4:3 (30fps mode): 15fps*
16:9 (25fps mode)/4:3 (25fps mode): 12.5fps*
“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.
Depending on the number of users connecting at the same time or the combination of features used, the frame rate may be lower than the configured value.
Check the transmission of images after changing settings.

Note
The bit rate for “Stream” is restricted by “Bandwidth control(bit rate)” on the [Network] tab on the “Network” page (→2.8.1 Configure the network settings [Network]). When a value with “*” attached is set, images may not be streamed.
When the refresh interval is short, the configured bit rate may be exceeded depending on the subject.
Depending on the number of users connecting at the same time or the combination of features used, the bit rate may be lower than the configured value.
Check the transmission of images after changing settings.
[Image quality]
Select the image quality of H.265 images from the following.
For “Constant bit rate”, “Frame rate”, and “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
Default: 3
[Smart Coding] - [GOP control]
By using “GOP control”, the transmission data volume can be reduced when there is little motion in the image.
Off/On(Low)/On(Mid)/On(Advanced)/On(Frame rate control)
Default: Off
IMPORTANT
When “On(Low)”, “On(Mid)”, “On(Advanced)”, or “On(Frame rate control)” is selected, recording to an SD memory card cannot be performed.
Note
When using “GOP control”, the refresh interval is increased when streaming H.265 images. For this reason, do not use it when the network environment has frequent errors.
“On(Low)”/“On(Mid)”/“On(Frame rate control)” can be selected only when “VBR” is selected for “Transmission priority”. “On(Advanced)” can be selected regardless of the “Transmission priority” setting.
When “On(Frame rate control)” is selected, the frame rate ranges from 1fps to the value set in [Frame rate*] depending on the size of image changes.
When “On(Frame rate control)” is selected, the display may temporarily become slower or faster when changing frame rates.
[Smart Coding] - [AUTO VIQS]
Maintains high image quality in the areas of the image containing moving objects, and reduces the transmission data volume in other areas of the image.
Off: Does not use “AUTO VIQS”.
On: Maintains high image quality in the areas of the image containing moving objects, and reduces the transmission data volume in other areas of the image.
Default: Off
Note
This feature can only be used for “Stream(1)”.
If “On” is selected, the VIQS setting set from the [Image quality] tab is disabled.
[Refresh interval]
Select an interval (I-frame interval; 0.2 - 5 seconds) to refresh the displayed H.265 images from the following.
If using under a network environment with frequent error occurrences, shorten the refresh interval for H.265 to diminish image distortions. However, the image refresh speed may be lowered and the configured bit rate may be exceeded.
0.2s/ 0.25s/ 0.33s/ 0.5s/ 1s/ 2s/ 3s/ 4s/ 5s
Default: 1s
Note
When “On(Low)” is selected for “GOP control”, the refresh interval is set to Max. 8s.
When “On(Mid)” is selected for “GOP control”, the refresh interval is set to Max. 16s.
When “On(Advanced)” is selected for “GOP control”, the refresh interval is set to 60s.
If “GOP control” is set to “On(Frame rate control)”, the frame rate ranges from 1fps to the value set in [Frame rate*] depending on the size of image changes.
The smaller the frame rate value, the longer the refresh interval. When the frame rate is the value set in [Frame rate*], the refresh interval is at Max. 16s.
[Transmission type]
Select the transmission type of H.265 images from the following.
Unicast port (AUTO): Up to 14 users can access a single camera concurrently. “Unicast port” will automatically be selected when transmitting images from the camera. When it is unnecessary to fix the port number for stream 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 port” manually to transmit images from the camera.
It is possible to fix the port number of the router used for stream transmission via the Internet by setting “Unicast port (MANUAL)” (→2.8.1 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 stream with multicast.
