If you need to set the zone to only detect object of specific categories, we place a category
filter before it. This filter is located in the floating panel
Programming elements
in the
Property filters
section. Again, using the drag and drop technique we instantiate the filter
and then we connect its output with the zone input. This way we have create a so-called
sequence filter. By double-clicking on the
Category
filter
we can select what object types
we want the filter to allow to pass.
You can create any number of detection zones you like based on the needs of dynamic
traffic control. All the zones can be connected to the same category filter.
