Aggregation Time - Vivotek SC8131 User Manual

The statistics in zone detection reports are described as follows:
Report tag name
Inward count
Sum Outward duration Sum of dwell time for objects that left the zone before the end
Total count
Average duration
Average count
The system default for the aggregation time is 60 seconds, which has effects on the
count of people and their dwell time in the zone, during a specific period of time. For
objects that still stay in the zone by the end of aggregation time, it is difficult to learn
their total dwell time. People's dwell time is calculated by adding the following sums:
1. The dwell time since objects entered till the end of aggregation time.
2. The dwell time of objects that left the zone during the aggregation time.

Aggregation time

Object A
30sec
Object B
30sec
Object C
Object D
Object E
Since object B and C did not leave the zone,
the dwell time will be time after they entered and
until the end of aggregation time.
In this way, setting the aggregation time higher or lower can affect the accuracy of dwell
time. Please contact our Technical Support for tuning this parameter.
