– View Rule: The selected Events will be displayed on Video Preview, and enables you to
setup VA Event.
– Object: Setup the object related configurations such as Sensitivity and Size to optimize the
VA detection.
* Sensitivity: As the value becomes bigger, the detection sensitivity increases. If there are
lots of motion in the screen such as trees, lower the Sensitivity value.
* Min/Max size: Set the object size to be detected.
* Show object size: The object size will be displayed on Video Preview.
NOTE: Recommendation on object size setting
* Indoor (10m distance, height about 170cm): Sensitivity 80, Min width size 2, Min height
size 6, Max width size 50, Max height size 60
* Outdoor (30m distance, vehicle): Sensitivity 80, Min width size 2, Min height size 4, Max
width size 60, Max height size 50
* In order to avoid merging of several objects into one or splitting of a single object into
multiple, please appropriately set sizes of minimal and maximal object that can enter the
scene.
* Great noise can cause unintended detections. Lower the sensitivity appropriately in
accordance to your environments.
Case
Two objects
are merged to
single object.
Reduce the max. size
of the object to avoid
two objects are merged
into single object.
Single object is
detected as
two objects.
The maximum and
minimum size of the
object is too small.
Enlarge the maximum
and minimum size to be
detected.
NOTE: In the following cases, video analysis function may be degraded or cause improper
detection.
* The brightness of the background is dark.
* Sudden light condition change from lighting or cloud.
* When the object is hidden or overlapped by other moving objects or facilities.
* When there is any light or light reflection toward the camera (for example: car in the
tunnel)
