[Transmission priority]
Select a transmission priority for “Stream” from the following.
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*”.
Default: VBR
Note
When “Frame rate” is set for “Transmission priority”, number of users who can access the camera may be limited.
[Frame rate*]
The maximum frame rate of Stream(1) for Source1/Source2 is fixed.
The frame rate of Stream(2) can be selected from the following.
When Dual sources [4:3](15fps mode) is used: 1fps/3fps/7.5fps/10fps/15fps
When Dual sources [4:3](12.5fps mode) is used: 1fps/3.1fps/6.25fps/8.3fps/12.5fps/25fps
When Single source [4:3](30fps mode) is used: 1fps/3fps/7.5fps/10fps/15fps/30fps
When Single source [4:3](25fps mode) is used: 1fps/3.1fps/6.25fps/8.3fps/12.5fps/25fps
Default: 15fps*
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––

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 bit rate may go over the set value depending on the subject.
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 “Frame rate”: Motion priority/Normal/Quality priority
“VBR”: 0 Super fine/ 1 Fine/ 2/ 3/ 4/ 5 Normal/ 6/ 7/ 8/ 9 Low
Default: 3
[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, image refresh speed may be reduced or 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.265 (or H.264) images from the following.
Unicast port (AUTO): Up to 14 users can access a single camera concurrently. “Unicast port1(Image)” 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 port1(Image)” 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. Refer to 1.1.1 Monitor images from a single camera for further information about the maximum concurrent access number.
