2nd Generation Motion Setting Questions

Just got the brand new hardwire 2nd generation. After reading all I can can’t figure out zones. It’s alerting me every time a car passes by but today an Amazon truck pulled up and delivered a package and the truck showed up but no video of the person delivering it who came onto the front stoop. I want To be able to see people who come to the front steps and deliver packages even if they don’t ring the door bell. And how do I turn off alerts for cars passing by? Thx!!
