[Important]
・When [Low], [Mid], [Mid], or [Frame rate control (Variable GOP4s-16s + Frame
rate control)] is selected, recording cannot be performed on the SD Memory
Card. If Advanced (fixed GOP 60s + 1s keyframe) is selected, the data can be
recorded on SD cards only with [Manual] [Schedule].
[Note:]
・Using GOP control increases the refresh interval for the H.265 (or H.264) image.
Therefore, do not use in network environments where there are many errors.
・[Low]/[Mid]/[Frame rate control (variable GOP4s-16s + frame rate control)] can
be set only when [VBR] is selected in [Transmission priority]. [Advanced (Fixed
GOP 60s + 1s keyframe)] can be set regardless of the [Transmission priority].
・[Low (variable GOP 1s-8s)], [Mid (variable GOP 4s-16s)], and [Frame rate
control (variable GOP 4s-16s + frame rate control)] can reduce the amount of
data when there is no detectable object (face, person, car, or motorcycle) in the
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] Selecting Low (variable GOP1s-8s)/[Mid (variable GOP 4s-16s)]/
[Advanced (fixed GOP 60s + 1s keyframe)]/[Frame rate antrol (variable GOP
4s-16s + frame rate control)] limits the bit rate.
If [H.265] is selected in [Stream encoding format]: [Off]/Low/Mid/Advanced/Frame rate control
If [H.264] is selected in [Stream encoding format]: [Off]/[Low]/[Mid(variable GOP 4s-16s)]
[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.
[0.2s]/ [0.25s]/ [0.33s]/ [0.5s]/ [1s]/ [2s]/ [3s]/ [4s]/ [5s]
