● SETUP SCREEN
To use the Motion Detection (MD) function
1. Select the <Motion detection> mode.
2. Select the sensitivity of separating
movement from the background.
You can select 5 levels of sensitivity (very
low/low/normal/high/very high).
3. Select the size of the object for
observation.
• Minimum size (pixel) : To restrict the
minimum movement to be observed,
select <Minimum size (pixel)> and
enter the width and height. The unit
is pixel, and you can select any value
equivalent to or higher than 32 x 32.
• Maximum size (pixel) : To restrict the
maximum movement to be observed,
select <Maximum size (pixel)> and
enter the width and height. The unit
is pixels, and you can select any
value up to 1920x1080.

`
Motions smaller than the specified
minimum size or bigger than the
maximum size are not detected. To avoid
unintended detections caused by great
and small noises, set minimum/maximum
motion sizes appropriately in accordance
to your environments.
`
Note that same motions on the same location can be differently detected in their detection size;
it is recommended to consider and include the tolerable difference when setting the minimum/
maximum detection sizes.
4. Set the area in which movement is detected.
You can drag the area on the screen. You can set up to 4 areas.
• Detection area : Sets the entire screen as excluded from detection, and adds
specified area as motion detection area. You can drag the area on the screen.
5. When done, click [Apply (
)].

Unlike the video analysis function, the motion detection function provides no overlay mark on the
screen. A yellow box appears at a side of the monitoring screen, and the operation function is
recorded in the system log.
