Peephole Camera records vehicles only, rarely people.

I have the peephole camera, which I love the idea of, but the execution is lacking. I have it set to monitor and record as tight as possible, while still maintaining the reason I ever bought it in the first place but it constantly alerts and records every vehicle that drives down the street while ignoring the vehicles that actually stop in front of my house, or worse, the people that walk right up to my door! I do not want to set the street as a privacy zone because as I said, I want to know who is parking in front of my house. But I do not care to know every single car that drives by. More importantly, or actually most important, I NEED it to actually monitor the area directly in front of my front door!
