Note :
●
Before configuring the motion detection settings, it is
recommended that you complete the settings related to image
resolution, compression, and motion detection exclusion areas.
Otherwise, you may need to adjust the sensitivity level in the
motion detection settings again when you change the picture
quality and set the exclusion areas at a later date.
Defining Motion Detection Exclusion
Regions
You can specify specific areas to be excluded from motion detection
to prevent the detection of irrelevant motion, such as trees swaying
in the wind or cars that drive past continuously in the background.
1
Select a camera from the [Device Manager] on
the [Camera Recording Administator] screen,
and click [Exclude Regions...] in [Settings...]
●
If the [Show Grid] check box is selected, the preview

Setting Buttons and Check Boxes
Note :
●
Note that when motion detection is set at short intervals, the
number of alarms may increase and a longer search time may
be required during playback.
●
When a camera is connected, flickers such as those of a
fluorescent light may cause a false motion detection. In this
case, set the camera to flickerless.
●
Noises in the camera image may also trigger a false detection.
Set the camera to prevent false detection even when the ACG
function is enabled, such as during nighttime.
Specifying Motion Detection.
Motion detection enables you to specify the timing to transfer
images from the camera, generate alerts, and trigger external
outputs (lights or sirens).
Note :
●
This feature is essential to the system’s operation. In order to
avoid unnecessary alerts during application, it is recommended
that you specify the settings for each camera carefully.
Depending on the physical location where the camera is
installed, it may be necessary to perform tests and adjustments
of the settings under different conditions (time of the day,
weather such as windiness, etc.).
1
Select a camera from [Device Manager] on the
[Camera Recording Administator] screen, and
click the [Motion Detection..] button in
[Settings...] to open [Adjust Motion Detection]
2
Specify [Noise Sensitivity] and [Motion
●
The [Noise Sensitivity] slider is used to determine the level
of change in the image pixel that is to be recognized as
motion. The
setting recognizes minute changes in
the pixel as motion. Areas in the image that have changed
when compared with the previous image are highlighted
(default color is green).
