Chapter 5 Settings
The motion detection processor uses this value as the standard value for
determining whether motion has occurred between frames.
Expert Mode
Select this check box on to configure detailed settings for the motion
detection area.
When this check box is selected, you can configure the following items.
Previous Frame
Specify, by number of frames, the number of images to compare as a
basis for determining that motion has occurred.
Caution
Setting this number high facilitates noise reduction, but processing speed
decreases due to the increase in processing load and memory usage.
Candidate Frame
The number of detections needed to recognize a candidate image as
moving is configured based on this value. The specified value is used
as a parameter for calculating the number of detections needed to
recognize a candidate image as moving.
Block Size X
Specify the horizontal length of the detection area in pixels.
Block Size Y
Specify the vertical length of the detection area in pixels.
Max Object Size X
Specify the maximum horizontal length of the detection area in percent.
Max Object Size Y
Specify the maximum vertical length of the detection area in percent.
Min Object Size X
Specify the minimum horizontal length of the detection area in percent.
Min Object Size Y
Specify the minimum vertical length of the detection area in percent.
Min Objects For Alarm
Specify the number of motion detection boxes for sending
notification of an alarm.

For cameras equipped with pan, tilt, and zoom functions, use this to change
the direction and zoom of the camera when configuring an area.

Once you have configured all the desired settings, click [Save] in the top
right of the window.
VMF
When using a metadata-compatible camera, you need to configure VMF (Video
Motion Filter) settings for motion detection by metadata.
A VMF is a filter for detecting specific motion phenomena from motion-related
metadata generated by the camera.
VMFs are available in two types, Moving and Unattended, and up to three can
be managed together as a VMF package. The filters in a VMF package can be
combined either sequentially, whereby each filter must be satisfied in sequential
order to trigger an alarm, or in parallel, whereby satisfying any one filter is
sufficient to trigger an alarm.
