Issues detecting traffic on this busy street

I could go on about the little issues these cameras have had the last month or so we’ve had them, bit it did catch a guy peering into our cars in the driveway a couple weeks ago. I had the back camera dialed in flawlessly where it wouldnt detect the constant traffic on the cross street visible in the screenshot, but the past 3-5 days it catches almost every car. No settings have been changed, it just all of a sudden started “motion” detecting instead of “person” detecting like it’s set up to do. Any help would be appreciated.

Maybe turn sensitivity down a notch?
