•
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:
VBR
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*
•
Default:
15fps*
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.
[Burst tolerance level]
Select how much the bit rate can exceed “Max bit rate (per client)*” by from the following.
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”.
[Max bit rate (per client)*]
Select a H.264 bit rate per a client from the following. When “Best effort” is selected for “Transmission
priority”, set the maximum and minimum bit rates.
64kbps/ 128kbps*/ 256kbps*/ 384kbps*/ 512kbps*/ 768kbps*/ 1024kbps*/ 1536kbps*/ 2048kbps*/ 3072kbps*/
4096kbps*/ 6144kbps*/ 8192kbps*/ 10240kbps*/ 12288kbps*/ 14336kbps*/ 16384kbps*/ 20480kbps*/
24576kbps*/ 30720kbps*
•
Default:
–
H.264(1): 16384kbps*
–
H.264(2): 4096kbps*
* The range of bit rates that can be configured for H.264 bit rates differs depending on the “Transmission
priority” and “Image capture size”.
When “Constant bit rate”, “Frame rate”, “Advanced VBR”, or “Best effort” is selected for “Transmission
priority”
