specify the multiple activation zones.
Up to four independent zones, where each zone is a user-
defined polygon with a maximum of 16 nodes. Each node
defined by fixed-point coordinate pair lying within image
boundaries. The first and last nodes should be identical. An
object’s size must satisfy the minimum area defined by the size
criterion (above) to be detected. The zone ID is reported along
with the event.
Trip Zone
Detects objects moving from one user-defined zone to
another; can also be used for “wrong way” detection. A Trip
Zone event occurs when an object(s) is detected moving
across the common edge shared by exactly two adjacent
zones. The zones are defined as two polygonal regions that
