license plate cannot be recognized. This function is only supported when Global or
China is selected for Country.
Replace I with 1: Always identify the character “I” as “1” (one).
Replace zero with O: Always identify the character “0” as “O” (letter O).
Replace Q with zero: Always identify the character “Q” as “0” (zero). Note this
option is only available on the engine version of V5000 or later.
License Plate Rule: You can customize up to six license plate rules and the
recognized plates will be converted to similar character to follow the rule. The rule
must be between 4 and 9 characters and consists of “A” (Alphabets), “D” (Numeric
digits) and “X” (Any). For example, if the rule is AA-DDDD, a license plate detected
as XY-123A will be converted to XY-1234 to follow the rule. The rule will be ignored
if none of the detected plate numbers follow the rule.
