[Refresh interval]
Select the refresh interval (I-Picture interval: 0.2 to 5 seconds) for the H.265 (or H.264) image
from the following.
If there are many errors in the network environment, the image will be less distorted if the refresh
interval is shortened.
However, the updating speed of the image may decrease or the bit rate may be exceeded.

image. [Advanced (fixed GOP 60s + 1s keyframe)] reduces the amount of data
regardless of the presence or absence of the sensing object.
・When [Frame rate control] is set, the frame rate can be changed from 1fps to
[Frame rate*] depending on the presence or absence of the sensing object.
・When [Frame rate control] is set, the display may temporarily slow or fast when
the frame rate is switched.
・[MULTI] When [GOP control] is set to [Low(Variable GOP 1s-8s)], [Mid
(Variable GOP 4s-16s)], [Advanced(Fixed GOP 60s w/1s key-frame)] or [Frame
rate control(Variable GOP 4s‑16s w/frame rate control)] is selected, the bit rate
will be limited.
・[MULTI4] [MULTI3] [GOP control] is set to [Low(Variable GOP 1s-8s)],
[Mid(Variable GOP 4s-16s)] or [Frame rate control(Variable GOP 4s‑16s
w/frame rate control)], the frame rate is limited to 7.5 fps maximum in 15 fps
mode, 6.25 fps maximum in 12.5 fps mode, 15 fps maximum in 30 fps mode, and
12.5 fps maximum in 25 fps mode.
・[New X Fixed-8M][New X Fixed-6M]If [Image capture mode] is set to [60fps
Mode] or [50fps Mode], [GOP control] cannot be used.
[Note:]
・If [GOP control] is set to Low (variable GOP 1s-8s), the refresh interval is set to
8s.
・If [GOP control] is set to Mid (variable GOP 4s-16s), the refresh interval is set
to 16s.
・If [GOP control] is set to Advanced (fixed GOP 60s + 1s keyframe), the refresh
interval is set to 60s.
・If [GOP control] is set to [Frame Rate Control (variable GOP 4s-16s + frame
rate control)], the frame rate can be varied between values set from 1fps to
[Frame rate*] according to the magnitude of the image change. The lower the
