The following general ALPR analytics are available in SharpZ3 OS.
Confidence score
The camera can assign a confidence score to license plate reads. This value is given as a

For information on how to enable the confidence score analytic, see Configuring SharpZ3 analytics in the SharpOS 13.7 Sharp Portal.
