Performance
Settings entered in the fields under
Performance
will
override the global defaults. Leave the fields blank to use
the global default values.
Frame Skip
This option determines how many frames
are skipped in recorded events. By default this is set to
0 which doesn’t skip any frames and means that every
captured frame is saved. Entering a number in this field
defines how many frames are skipped between every
recorded frame. For example, if 2 were entered in this
field, two frames are skipped in between every single
frame recorded.
Image Buffer Size
Determines how many frames are
held in the image buffer. 40 is the default value.
Replay Image Buffer
Defines the total number of
frames for the replay image buffer. 1000 is the default
value.
Warm Up Frames
Specifies the number of frames
processed before analysis occurs. 25 is the default value.
Analysis & Recording
Reference Image Blend %
Every analyzed image is a
composite of previous images and is formed by applying
the current image as a certain percentage of the previous
reference image. The value entered here determines the
percentage of the previous image used. By default the
value is set to 10%. A higher value would make slower
progressing events less detectable. Typically if this
number is modified, it should be adjusted down.
Alarm Frame Count
Specifies how many consecutive
alarm frames must occur before an event is generated. The
default value of 1 ensures that any alarm frame generates
an event. Although a value of up to 16 may be entered
here, typically anything larger than 3 or 4 will not be
useful.
Event Frame Pre Padding
When motion is detected, this
is the amount of frames included in the recording before
the motion occurs. By default this is set to 30.
Event Frame Post Padding
When motion is detected, this
is the amount of frames included in the recording after the
motion occurs. By default this is set to 30.
Recording Clip Length
Defines the maximum length of
a recording clip in seconds. The default is 600 seconds
(10 minutes).
