TIME 05:00 |
After five seconds have elapsed, the first frame of the violation
appears on the Screener’s video monitor and is presented to AirCleaner’s video
input. However, due to human visual reaction delay, the Screener has not yet
pressed the VIDEO panic button.

TIME 06:00 |
After one more second in time has elapsed (6 seconds in total) the
human operator now recognizes the violation, pushes the VIDEO panic button
and holds down the button. Since the Reaction Time for this Screener is
programmed for 2:00 Seconds, the button trigger is advanced forward in time
by AirCleaner, and is marked in the video one second before the violation.
