sensitivity setting in app

[user_617650665832448_617650665832448]

Hi
I have an Argus 2e solar camera up and running. In the app I found out how to set the pir setting, however, I can't find the sensitivity setting. My problem is I am close to the highway and it keeps pickup passing vehicles. I can't adjust it not to include that area and still pickup up movement in my driveway.
Thanks in advance
