The higher the resolution, the more accurate the detail in the image. With analog technology, a recorded image generally has no more than 0.1 megapixels (CIF). One single camera with 3.1 megapixels records around 30 times more detail. As a result, larger image areas with up to 360° allround views are possible, thus reducing the number of cameras, and therefore the costs. For example, four lanes of a gas station can be recorded with one camera instead of four conventional cameras.
