Setting the detection depth
Set the detection depth of the detected areas. By setting the detection depth, it is possible to automatically calculate the size of
object to be detected on the screen to reduce the detection failure.
To calculate the detection depth properly, mount the camera horizontally.
Step 1
Display the setup page for camera's i-VMD function, and
select the desired camera and scene. (+ Page 114)

Select the [Detection depth] tab.
→ The [Detection depth] tab will be displayed.
Step 3
Select the [Setup] button.

Step 4
Draw 2 square markers between the nearer sides (lower
areas in the image) and the farther sides (upper areas in the

each square markers.
Normally, assuming that people go forward and backward, it
is possible to calculate the correct depth by drawing the
larger marker for the nearer side and the smaller marker for
the farther side.
