Setting the motion detection parameters
These settings determine how great the variation must be, how large the changed area must be
as a proportion of the whole detection area, and how long the variation must continue before it is
recognized as motion and the specified action is performed. These 3 parameters are specified as
the "Sensitivity", "Area Ratio" and "Duration" respectively.

The area in which motion is detected appears as a
red rectangle in the image. You can set the amount of
motion required before the red rectangle is displayed
while monitoring the actual image.
When the variation occurs in the image, the detection
indicator shows the following:
[Green] ..... The area of the change was smaller than
the specified area ratio.
[Yellow] .... The area of the change equalled or
exceeded the specified area ratio.
If all the detection conditions are satisfied and motion
is detected, a red peak block appears.
You can set the amount of motion for which the peak
block is displayed while monitoring the actual image.
