I don't see how you can do that with just one camera, unless you're looking for more of an "overview" kind of shot.
Normal advice is to keep the camera as close to head-level as possible (so you can capture faces), but if you do that, I don't see how you could cover the garage door, front door, and parking area in the same shot.
You could put the camera higher up on one corner, but the sacrifice would be be seeing more "tops of heads" than actual faces.
If you wanted to start with just one camera, see how it goes, and maybe add more, maybe put it to the upper left of the garage door (under the roof underhang), so it'd capture everything in front of the front door and in the parking area? Wouldn't get much of anything in front of the garage door, though?
I'm new to all of this, so that's just a random thought until some of the more seasoned pros come by.
