Range

Function

This API is used to get parameter range for AI > Setup > License Plate Detection page.

Note:

The Range provides reference information for client UI input limits and API request limits. When sending Get and Set requests, the parameters must be strictly limited according to the Range, otherwise the request may be rejected by the device.
