You don't need a good camera to read number plates.
What you need is the correct lens for the distance you are at and a
light source that doesn't reflect back and overload the sensor.

Easiest way is to have an external illuminator a few feet away from the
camera.

Anyway as far as I am aware vehicles only arrive at a burglary in the
closing stages and sure as hell their number plates will be iffy.

Quite possibly.


I did wonder about stacking software to use multiple images and make a
number plate legible but couldn't find anything to try.

That's a clever idea. Is it already done do you know (is that why you
generally see two cameras doing this sort of thing)?

Yes the software is used in astronomy and forensics but as I say I
have not seen any.

Waste of time, you can't get information back that isn't there.
