    Vehicle trigger settings - missing subsequent vehicles after initial capture

    My LPR camera detects single vehicles well. But when vehicles pass in quick succession, while BI will trigger consistently for each vehicle, the footage sent to CodeProject.AI has missed vehicle #2, #3, #4 etc. They have already passed and are out of frame. The second vehicle is triggering...
