Procedure

  4. On the Set Thresholds screen, tap Advanced for each of the labels that you want to monitor in the scene.
  5. On the Advanced screen, tap Additional Rules.
  6. Select Inspect When Label Detected. The app returns to the Advanced screen.
  7. On the Advanced screen, set Frames To Consider to 1. This value means that every frame is checked.
  8. On the Advanced screen, set Frames Label must Be Present to 1. This value forces an inspection on each frame.
  9. On the Advanced screen, set Frames Without Label To Reset to 0. This value forces a reset after an inspection is done on each frame.
    Note: You can set the frames per second rate in Configure Device > App Settings > Frame Rate Throttle.
