•
On(Low):
Maintains high image quality in the areas containing heads, people, cars, and motorcycles and
medium image quality in other areas while reducing the transmission data volume.
•
Default:
Off
Note
•
This feature can only be used for “Stream(1)”. If “On(High)” or “On(Low)” is selected, the VIQS setting
from the [Image quality] tab is disabled.
[Smart Coding] - [Smart P-picture control]
Controls the area other than the areas containing heads, people, cars, and motorcycles to be reduced the
transmission data volume of P-picture.
•
Off:
Does not use “Smart P-picture control”
•
On:
Controls the area other than the areas containing heads, people, cars, and motorcycles to be reduced
the transmission data volume of P-picture.
•
Default:
Off
Note
•
This feature can only be used for “Stream(1)”. If “On” is selected, the VIQS setting from the [Image
quality] tab is disabled.
•
When “On” is selected, on non-detected area, movement may not be smooth or noise appears.
[Smart Coding] - [GOP control]
By using “GOP control”, the transmission data volume can be reduced.
•
When “H.265” is selected as the “Stream encoding format”:
Off/ Low(Variable GOP 1s-8s)/
Mid(Variable GOP 4s-16s)/ Advanced(Fixed GOP 60s w/1s key-frame)/ Frame rate control(Variable GOP
4s-16s w/frame rate control)
•
When “H.264” is selected as the “Stream encoding format”:
Off/ Low(Variable GOP 1s-8s)/
Mid(Variable GOP 4s-16s)
•
Default:
Off
IMPORTANT
•
When “Low(Variable GOP 1s-8s)”, “Mid(Variable GOP 4s-16s)”, or “Frame rate control(Variable GOP
4s-16s w/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.
•
“Low(Variable GOP 1s-8s)”/“Mid(Variable GOP 4s-16s)”/“Frame rate control(Variable GOP 4s-16s w/
frame rate control)” can be selected only when “VBR” is selected for “Transmission priority”.
“Advanced(Fixed GOP 60s w/1s key-frame)” can be selected regardless of the “Transmission
priority” setting.
•
By using “Low(Variable GOP 1s-8s)”/“Mid(Variable GOP 4s-16s)”/“Frame rate control(Variable GOP
4s-16s w/frame rate control)”, the transmission data volume can be reduced when there is no target
to be detected (people’s face, body, vehicle and two-wheel vehicle) in the image. By using
“Advanced(Fixed GOP 60s w/1s key-frame)”, the transmission data volume can be reduced
regardless of presence/absence of target to be detected in the image.
•
When “Frame rate control(Variable GOP 4s-16s w/frame rate control)” is selected, the frame rate will
change within the range between 1fps and a value set in [Frame rate*] according to presence/absence
of target to be detected.
•
When “On(Frame rate control)” is selected, the display may temporarily become slower or faster when
changing frame rates.
