Best event to detect person and cars?

[saunders1989]

If you were setting up events for knowing if a person was coming onto our driveway or a car enters the driveway what events would you setup (pic for context). I’ve tried a few other events but none seem to be triggering let alone reliable.

I currently have 2 line crossing events (one for people and one for cars) but since getting a second car the line crossing of a person isn’t always detected. Also if headlights shine onto my drive the event is trigged from my parked car.
