Maybe, but the real problem is bitrate. In high light environments, the shutter speed is plenty fast enough to catch a plate, but you still get a blur because there's not enough bitrate to render a sharp image on every frame. You could be running 1000 frames a second (effectively you ARE if you're in full sunlight - the camera is taking a 1/1000th second image 60 times a second) and you still wont' be able to read the plate if you've got a bitrate like 18 Mbps or something.
