Analytics rules - Zone detection (2nd type)
• Detection area

Up to 64 clicks can be used to draw a plygon, where you expect moving objects to pass
through.
• Delay for _ seconds
:
Enter delay: People must be present in the zone for xx seconds before the counting
takes effect. When staying for a time too short, people may not have the intention for
staying or entering.
Leave delay: Taking as an effective count after people left the zone for xx seconds. If a
man leaves a zone temporarily for 1 or 2 seconds, he may not intend to leave.
Note that if you configure the Enter delay as 3 seconds, the count takes effects on the
4th second.
• Object type

filtering situations such as when human passing by holding a cardboard box or carrying
a large, tall backpack.
