To navigate to the ALPR settings page, click Configuration > Analytics > ALPR settings.

The following information is displayed:


Select which plate origin the SharpZ3 is reading.


Select this option if you want the SharpZ3 unit to attempt read the license plate origin. Depending on the region, this can refer to the issuing state, province, or country.
Vehicle make
Select this option if you want the SharpZ3 unit to attempt to read the vehicle’s make from the brand or logo (Honda, Toyota, and so on).
NOTE: This setting is not recommended for MLPI installations.
Confidence score
The SharpZ3 assigns a confidence score percentage to each license plate read. This value indicates how confident the SharpZ3 is in the accuracy of the read.
NOTE: License plates that contain similar characters such as 8 and B are more difficult to read and generally produce reads with a lower confidence score.
Vehicle type and color
Select this option if you want to include the vehicle type and vehicle color with plate reads. Based on the context image, the Sharp unit can detect if the vehicle is a bus, passenger vehicle, motorcycle, pickup, truck, work van, or an unknown vehicle type. In addition, the Sharp unit can detect if the vehicle is black, white, blue, brown, green, gray, orange, red, or yellow. Colors excluding white and black are also assigned light, neutral, or dark according to the color analysis.


Reading mode
Select one of the following reading modes:
Select this for plates to be captured continuously. This is the default setting.
When this option is selected, the SharpZ3 captures plate reads continuously as long as the selected input signal meets the condition defined (high/low). You must select an input and specify whether the state is high or low.
Generates reads from a specific camera only while an input's status meets the defined high or low condition. This option is required if using the AutoVu™ car camera switch.
