These cams are no different than any other camera, like a Nikon DSLR or a Kodak Instamatic. Exposure is controlled by the shutter speed and the Iris opening (F-stop in photography lingo). As you know, the Iris (F-Stop) will control the DOF. Just like sports photography.
Trying to match someone else's caps is futile. Their situation is different than yours. Distance, angle, street lighting, cabling, hardware, etc is all different. That is why we say to use someone else's settings as a starting point and then adjust to your specific FOV.
