Ditto FM.
The sensitivity settings are directly related to size and distance.
Meaning, if you set sensitivity to the area on your driveway close to the house, say withing 40 feet, then it will not trigger in the distance. And, if you set sensitivity to trigger 400 feet out, then it will trigger everything, including leaves, squirrels, and ants (well, maybe not ants), close up! lol
You can resolve this by copying the camera to 2 or even 3 copies, and setting each of those cameras to detect further out sequentially, and setting each cameras sensitivity settings. For example, Cam1 would detect up to 40 feet, camera 2 40-100'. Cam3 100-200...
Thinking about it, you would really only need 2. One for the end of the driveway, and the original for closer. If someone comes into your driveway and does a few donuts, you'll still be alerted by the far-cam, and still get everything recorded in the original.
I've tested this with my street view. And it works well.
