License plates in daylight are tricky. At night they may be basically impossible. Sony sensor is your best bet but I wouldn't take very big bets on it.

I haven't had ANY cameras at all that could reliably read a plate in daylight. That's several Chinese cameras, a Contour Roam, a GoPro Hero3 White, an original Sony ActionCam. If they're moving relatively slow, maybe 15 MPH faster than you at most, you'll probably catch them in daylight, but faster than that, probably not.

When you get into low light, most cameras reduce their shutter speed. At 1/30 second, a car moving at +15 MPH will have a pretty blurry plate. In very low light cameras either go to black or drop to frame interpolation where they will go to 1/15 second shutter or less and paint the same frame twice. At 1/15 second there's basically no chance to read a plate unless the car is basically stopped.
