There's more to it than resolution. The systems I work on recognize fine features of objects at high speed. Not facial recognition, but similar. One of those systems has an imaging sensor similar to the one you mentioned. It works quite well, in part because the camera is optically excellent, in part because it provides rich and accurate color data, and in part because we tightly control the environment that the image is captured in. In a less controlled environment, or if using lower quality sensors or optics, the results would be poor.
