camera issues

I have a stick up camera on my garage facing the driveway/street. It motion detects people walking by on the sidewalk, cars driving by (sometimes) but not cars entering or leaving the driveway, or people walking on the driveway. How do I fix this?

Motion sensors in cameras work better detecting motion that goes across it’s field of view. So angling it so most motion will be crossing it would result in better detection.
Some cameras like the floodlight offer custom zones. So, you could make 3 zones in front of the camera that objects will cross.
I hope this helps.
