This depends on the situation. In my situation, I've never had a camera (out of 12, including a GoPro) that reliably could get a clear plate image, but I'm talking about cars going past me at 60 MPH. Even at 60 FPS and high bitrate, the plates are just blurs. If I'm in city traffic with 25 MPH cars, it's very easy for even a basic camera to make out a plate.
