♦ Setting the detection mask
In this step, the dots which will activate the MOTION DE-
TECTION function are set. Images inputted from each of
the connected cameras are divided into a 10 x 12 vertical-
horizontal grid. The DETECTION MASK can be selected
as desired from the 120 dots displayed within the grid, and
this setting can then be established.
Example: Using the images provided by the camera chan-
nel set in SELECTION CAMERA NO., the right half of the
screen is selected as the DETECTION MASK and the ac-
tivate symbol “ ” is displayed. (The inactive symbol “ • ” is
displayed on the left half of the screen.) The default setting
is active “ ” for the entire area in the DETECTION MASK
setting.
“ ” : Active symbol (Indicates the area where CH.
MOTION DETECTION is active.)
“ • ” : Inactive symbol (Indicates the area where CH.
MOTION DETECTION is inactive.)
1. After step 3 of M-DET SETTING procedures on page 38.
Turn the JOG dial to select the SET DETECTION MASK and
turn the SHUTTLE ring to the right.
• The <SET DETECTION MASK> menu will appear.

♦ Sensitivity setting
In this step, the detection sensitivity to movement within
the image data is set. For each camera, image data is sam-
pled and compared every 0.6 seconds. SENSITIVITY is
the difference in the degree of brightness between the sam-
pled images, and is divided into settings of five different
levels. Select “HIGHER” to make the unit sensitive to the
even the smallest changes. Please note, however, that
false alarms may be caused by, for example, the flick-
ering of fluorescent lighting fixtures.
Example: Setting the SENSITIVITY to “HIGH” (the default
setting is “MED”).
1. After step 3 of M-DET SETTING procedures on page 38.
Turn the JOG dial to select the SENSITIVITY and turn the
SHUTTLE ring to the right.
• The sub-item will start flashing.
