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 too short, the actual bit rate may exceed the set bit rate depending on the subject.
This setting is common among Cam. 1, 2, 3, and 4.
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
Default: 5 Normal
This setting is common among Cam. 1, 2, 3, and 4.
[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)
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 (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)” are available only when “VBR” is selected for “Transmission priority”. “On(Advanced)” can be set 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.
This setting is common among Cam. 1, 2, 3, and 4.
[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
If “Auto VIQS” is “On”, the VIQS setting set from the [Image/Position] tab is disabled.
This setting is common among Cam. 1, 2, 3, and 4.
[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 become longer than the set value or the actual bit rate may exceed the set bit rate.
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.
This setting is common among Cam. 1, 2, 3, and 4.
[Transmission type]
Select the transmission type of H.265 (or H.264) images from the following.
Unicast port (AUTO): Up to 24 users can access the 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 24 users can access the 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)” (→2.8.1 Configure the network settings [Network]). Refer to the operating instructions of the router in use.
Multicast: Unlimited number of users can access the 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 camera images for further information about the maximum concurrent access number.
