A custom event you create can be linked to detection zones and actions on the AI Event screen just like any other event. You can edit or delete events and leave a memo in the [Created custom events] list. The default stabilization time is 1 second and is used to reduce false positives caused by a flickering object box. Past logs of a deleted custom event can still be queried on the Logs screen.
