The advantage to a cctv c-mount camera is that the lens can be changed. If you need to see further than 35 or 40 ft then you'll need a c-mount camera with a special lens. An example of where you might use a fixed 4mm lens is in a small office, or at home to focus on your driveway. A higher millimeter lens will provide further distance, but narrows the field of view.
The clarity of the images on CCTV cameras depends to great degree on the number of TV Lines (TVL) the camera produces. As a general rule, the more TV L the better the image. Cameras with 520 TVL will produce better images than those with 420 TVL.
