Nothing is more important that the right location for your camera.
No-one can place a camera perfect on the first try, plan to move it a couple of times until you get it just right. Make temporary installations at first; once the location has proven that it can do the job then make the installation permanent.
Place the camera at natural choke-points, that is where cars naturally slow down. PS. a stop sign is not a natural choke point, fleeing burglars will blast through the stop sign.
