Members

struRegion

Coordinates of detection region, refer to the structure NET_VCA_POLYGON for details.

fSpacingThreshold

Distance threshold, range: [0,10.0], default: 1.0, unit: m

bySensitivity

Sensitivity, range: [1,100]

byDetectMode

Detection mode, compared with distance threshold: 1-more than, 2-less than

wDuration

Event time duration, unit: second, which ranges from 1 to 3600, default: 2
