I've setup an MV72 at a range of about 15m and can keep the number plates ok. I tested a snapshot with openalpr.com and it was able to recognise the number plate as well.
I can't decide if I should post the picture as it is not my number plate, so to err on the side of privacy and caution I have decided not to.
However below are the settings I changed. I set:
- Optical zoom to the max at x2.
- Aperture to about 50%.
- Sensor crop to the region where I am most expecting to see number plates.
- Then I used the "Focus on a specific area" option to focus on where I expected to see the number plate the most in the frame.
