[Transmission priority]
Select a transmission priority for “Stream” from the following.
Constant bit rate: H.265 (or H.264) images will be transmitted with the bit rate selected for “Max bit rate (per client)*”.
VBR: H.265 (or H.264) 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 image quality is fixed, and the recording capacity changes according to the “Image quality” setting and conditions of the subject.
Frame rate: H.265 (or H.264) images will be transmitted with the frame rate selected for “Frame rate*”.
Best effort: In accordance with the network bandwidth, H.265 (or H.264) images will be transmitted with the maximum bit rates that are set for “Max bit rate (per client)*”.
Default: Frame rate
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.
1fps/ 3fps/ 5fps*/ 7.5fps*/ 10fps*/ 12fps*/ 15fps*/ 20fps*/ 30fps*/ 60fps*
Default: 30fps*
Note
“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.
When the “Image capture mode” is set as “2 mega pixel [16:9](60fps mode)” or “1.3 mega pixel [16:9](60fps mode)”, Stream(1) is fixed to 60fps. Also, Stream(2) to Stream(4) can select up to a maximum of 30fps.

When 60fps mode is selected, settings up until 24576kbps can be configured.
Note
The bit rate for “Stream” is restricted by “Bandwidth control(bit rate)” on the [Network] tab on the “Network” page (→2.9.1 Configure the network settings [Network]). When a value with “*” attached is set, images may not be streamed.
[Image quality]
Select the image quality of H.265 (or H.264) images from the following.
For “Constant bit rate”, “Frame rate”, and “Best effort”: Motion priority/Normal/Quality priority
“VBR”: 0 Super fine/ 1 Fine/ 2/ 3/ 4/ 5 Normal/ 6/ 7/ 8/ 9 Low
Default: 5 Normal
[Smart Coding] - [GOP control]
By using “GOP control”, the transmission data volume can be reduced when there is little motion in the image.
When “H.265” is selected as the “Stream encoding format”: Off/On(Low)/On(Mid)/On(Advanced)
When “H.264” is selected as the “Stream encoding format”: Off/On(Low)/On(Mid)
Default: Off
Note
This setting is available when “Transmission priority” is set to “VBR”.
When using “GOP control”, the refresh interval is increased when streaming H.265 (or H.264) images. For this reason, do not use it when the network environment has frequent errors.
[Smart Coding] - [Smart Facial Coding]
Maintains high image quality in the areas of the image containing people's faces and moving objects, and reduces the transmission data volume in other areas of the image.
Off: Does not use “AUTO VIQS” and “Smart Facial Coding”.
On(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.
On(Smart Facial Coding): Maintains high image quality in the areas of the image containing people's faces and 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)”.
When “2 mega pixel [16:9](60fps mode)” or “1.3 mega pixel [16:9](60fps mode)” is selected for “Image capture mode”, this function is not available.
When the camera is used in environments of 40°C or higher, the effectiveness of the smart facial coding will be reduced.
Depending on the object, a high image quality may be maintained even in areas that do not contain a person's face.
[Refresh interval]
Select an interval (I-frame interval; 0.2 - 5 seconds) to refresh the displayed H.265 (or H.264) images from the following.
If using under a network environment with frequent error occurrences, shorten the refresh interval for H.265 (or 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
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.
[Transmission type]
Select the transmission type of H.265 (or 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 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 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 stream transmission via the Internet by setting “Unicast port (MANUAL)” (→2.9.1 Configure the network settings [Network]). Refer to the operating instructions of the router in use.
