observation.
•
Minimum size (pixel) : To restrict the
minimum movement to be observed,
select <
minimum size (pixel)

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 1280x1024.

`
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.
