[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)*”.
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*
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.
•
Depending on the number 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.
[Max bit rate (per client)*]
Select an H.265 (or H.264) bit rate per a client from the following.
64kbps/ 128kbps*/ 256kbps*/ 384kbps*/ 512kbps*/ 768kbps*/ 1024kbps*/ 1536kbps*/ 2048kbps*/ 3072kbps*/ 4096kbps*/ 6144kbps*/ 8192kbps*/ 10240kbps*/ 12288kbps*/ 14336kbps*/ 16384kbps*/ 20480kbps*/ 24576kbps*/ –– FREE ENTRY––
When “–– FREE ENTRY––” is selected, the bit rate can be freely entered.
* The range of bit rates that can be configured for H.265 (or H.264) bit rates differs depending on the “Transmission priority” and “Image capture size”.

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.
•
Depending on the number 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 (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
[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)/On(Frame rate control)
•
When “H.264” is selected as the “Stream encoding format”: Off/On(Low)/On(Mid)
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 (or H.264) 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.
Note
•
This feature can only be used for “Stream(1)”.
•
If “AUTO VIQS” is on, 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 (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
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 (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.
•
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. Refer to
1.1.1 Monitor images from a single camera for further information about the maximum concurrent access number.
•
