■ SENSITIVITY
This item is used to set the sensitivity of detecting the
changes of the loaded video data. Video data is sampled
every 0.5 second and compared with each video data of
0.5 second before for each camera. The sensitivity setting
is divided into the 5 levels of difference in brightness.

Setting (default: “HIGH • • < < < LOW”)
“HIGH • • • • < LOW,” “HIGH • • • < < LOW,”
“HIGH • • < < < LOW,” “HIGH • < < < < LOW,”
“HIGH < < < < < LOW”
Sensitivity increases as “<” increases from
“HIGH • • • • < LOW” to “HIGH < < < < < LOW.”
To detect the slightest changes, set to
“HIGH < < < < < LOW.” However, detection may
not operate properly due to flickering of fluorescent
lighting, etc.
1. In “SELECTION CAMERA NUMBER,” select the camera
for which the sensitivity is set.
2. Display the desired setting in “SENSITIVITY” and press
the ENTER button.
• The setting item is determined.
■ MOTION THRESHOLD
This item is used to set the minimum number of dots for
starting the motion detection operation from the number of
active dots within the detection area. Motion detection
function operates when detecting the change that exceeds
the number of dots set as the minimum.

Set MOTION THRESHOLD to the number less
than the number set as the active dots in the detec-
tion area. The motion detection function does not
operate when setting MOTION THRESHOLD to a
value exceeds that number.
1. In “SELECTION CAMERA NUMBER,” select the camera
for which the motion threshold is set.
2. Display the desired setting in “MOTION THRESHOLD” and
press the ENTER button.

• During test operation, active areas of motion detection are
displayed using “ • .” “

is met the conditions of sensitivity and MD lock out time is
detected. If the motion detection does not operate properly,
set the conditions again.
This test is executed under the condition you have
set in the
screen.
