It all comes down to the lens you use and of course the screen size you view it on. Most packaged cctv systems will use a wide angle (2.4 - 3.5mm) lens. This will give a wide picture but specifics within the picture are small. Going to something like a 12mm lens will bring everything up closer but the picture wil not have as broad coverage.

If your looking at something like a driveway then try getting something like a 5 - 25 mm varifocal lens
