4. After masking areas, press the [SET]
button more than 2 seconds. "MOTION
DET" menu appears on the monitor screen.
5. Move the cursor to "ALARM", select "ON"
or "OFF".
ON: Turns on alarm output in the demo mode.
OFF: Turns off alarm output in the demo mode.
Default setting: OFF
6. Move the cursor to "DISPLAY MODE ", press
the [SET] button to see the present setting.
Demo Mode
The demo mode divides the screen into
48 blocks and monitors changes in the
luminance in each block. It also masks
any part of the picture where there is
a change in average luminance that
exceeds the currently specified detection
sensitivity level. The demo mode results
can be used to determine the optimum
detection sensitivity level (step 7) and
the areas of the screen that need to be
masked (step 3).
7. Move the cursor to "LEVEL", press the
[LEFT] and [RIGHT] buttons to set the
level. Move to "+", the level increases,
move to "-", the level decreases. Repeat
steps 6 and 7 to obtain the optimum
detection level.
Detection Conditions
Object Size: The picture size on the screen
should be larger than 1/48 of
the actual picture size.
Subject Contrast: The contrast ratio between
Object Speed: The allowable time range
for the object to pass from
one edge of the screen
to the other is 0.1 second
to 0.8 second. Movement
that is faster or slower than
this cannot be detected.
But when the contrast ratio between the
background and the moving object is
sufficient, the restriction to object size
and speed can be relaxed.
the background and the
moving object must be at
least 5 % (at the maximum
LEVEL setting).
8. Move the cursor to "DWELL TIME", press
the [LEFT] and [RIGHT] buttons to select
an alarm detect dwell time.
After alarm detection, the next alarm is not
detected until the specified dwell time elapses.
Display in the sequence shows as below.
2S
5S
10S
Default setting: 2S
9. Move the cursor to "RECOVER TIME", and
press the [LEFT] or [RIGHT] button to
select an alarm reset time setting.
Display in the sequence shows as follows.
When "OFF" is selected, it cannot be reset
before other operation.

Note:
• Use the mask setting to mask areas where
there is wind movement of curtains, etc.
• Use a lower sensitivity level (LEVEL)
setting for areas where illumination is
low and prone to digital noise. Also note
that operation error can occur when
the illuminance of a subject is changed
suddenly by the headlights of passing
cars, turning lights on or off, etc.
• There is a delay of about 0.2 second from
the point that the camera detects change
(movement) in the image and the point
that a signal is sent to the alarm terminal
of a VTR, etc.
• Alarms are not output when ZOOM,
FOCUS or other functions are operating.
• When the motion detector is set to "MOTION
DET" or "SCENE CHANGE", it outputs alarm
data during the blanking period. This can
cause operational problems for a VTR or
other device that uses a time code signal,
etc. Turn off the motion detector when not
using coaxial communication.
• The motion detector is not intended for
use as specialty device for the prevention
of theft, fire, etc. The manufacturer
assumes no responsibility for any
accidents that occur or any losses
incurred while this product is being used.
