Description
Shadow Screen
Enable
Select the On check box to enable this function.
This function is aimed at eliminating an object's shadow and
representing only the object itself in the object box; several objects
with their shadows partly overlaid can be told separately. So this
function can give user a precise clue of where the object really
locates. However, if an object’s part looks like the object’s shadow,
it’s likely that this part will be identified as a shadow and eliminated.
Sensitivity
The larger this value is, the easier an alarm will be to be triggered by
low-contrast or tiny objects.
Isotherm Filter
Select the On check box and set Upper Limit Threshold and
Lower Limit Threshold on your own needs.
This function is aimed at diminishing false alarms caused by waving
water.
Tracking Overlap
Rate
When overlap rate of an object at this moment and at earlier time is
smaller than the rate you have set, this object can be detected and
an alarm is triggered.
Valid Tracking
Distance
Only when an object’s moving distance is larger than valid tracking
distance you have set, this object can be detected and an alarm is
triggered.
Valid Tracking
Time
Only when an object’s moving time is larger than valid tracking time
you have set, this object can be detected and an alarm is triggered.
