Operator Description Type of value Example
> Greater than the specified value. Numeric [Confidence Score] > 80
< Less than the specified value. Numeric [Confidence Score] < 75
= Equal to the specified value. Numeric [Confidence Score] = 80
Text [Vehicle Make] = "Toyota"

endsWith Ends with the specified value. Text [State Name] endsWith "C"
matches Respects the regular expression. Text [PlateNumber] matches "[02468]$"

Identifiers

The following table lists the common identifiers that can be used and the corresponding value type, as well as descriptions and examples.
Identifier Description Type of value Example
PlateNumber Plate Number read by the Sharp. Numeric [PlateNumber] contains "123"

Vehicle Type Certain license plates include character symbols that identify specific vehicle types (for example, taxi, transport, and so on). The Sharp can read these symbols, and display the vehicle type. Text [Vehicle Type] = "Taxi"

Confidence Score The Sharp assigns a numerical value (from 0 to 100) to each license plate read. This value shows the accuracy level of the read. Numeric [Confidence Score] = 80
Speed Sharp cameras are able to estimate a vehicle’s approximate speed. Numeric [Speed] > 50
Speed.Unit Depending on the Sharp context used, the unit of speed is measured in km/h or mph. For the US context speed is measured in mph. Text [Speed.Unit] = "mph"
