LPR event when recognition ends.

I would like to be able to determine when a car has left the field of view of a camera. Is there an event I can register to, that fires when a camera stops recognizing a license plate?

The only events that are generated from the XProtect LPR are plate detection events. You will not be able to get an extra event signalling that now the plate has left the view and the car has moved on..

Trying to think creatively. After a plate detection you will have motion detction while the car moves away perhaps followed by a period of no movement in the picture. Maybe this could be used to time an event. I am not sure, maybe testing will need to be done to see if it is possible..
