Ah that's a whole other thing about Periodic AI Inspection ignore stationary objects etc. etc.My mistake, I mistook your original comment thinking you are talking about number of lines; now I see, you are talking about multiple objects in the same line. Yes, other additional car or trucks are stationary, meaning, those are present in the path (parked) when new car or truck comes by. Then CPAI detects those and makes multiple entries in that one line. I don't know how to make CPAI to only report the new one that is arriving and to ignore the ones already stationed or parked.
I don't know if setting that up will lower your detection time though, I was (falsely) operating under the assumption it was only supposed to be finding one thing and the multiple items were it finding the same thing using multiple models.
Ignore me!
