Output Tracks

Output track Description
Result Contains one record for each object that crosses the tripwire. The record is created when the object leaves the scene, and therefore includes the object's path after crossing the tripwire.
ResultWithSource

The same as the Result track, but each record also includes the best source frame.

Alert Contains one record for each object that crosses the tripwire. The record is created as soon as the object crosses the tripwire. There are no subsequent alerts for the same object.
AlertWithSource

The same as the Alert track, but each record also includes the source frame.

To see an example record, use the action GetExampleRecord.
