Best Practices and Considerations

• Isolate the primary plate characters: Ensure only the core plate number is captured within the alignment box. Avoid capturing extraneous text on the license plate, such as the state, province, or jurisdictional mottos. If the camera iconcaptures insteadheader oftext typing.(e.g., "Indiana" or "Ontario"), the read will likely be unsuccessful or inaccurate.

• Provide appropriate camera permissions: Make sure to allow access to the devicesdevice's camera,camera awhen notificationprompted. If permissions are accidentally denied, the OCR feature will popfail upto askinglaunch, aboutand this.field Oncepersonnel allowed,will thebe cameraforced opensto withuse amanual greentext boxentry until permissions are restored in the middledevice ofsettings.

Check your scan results: If the search returns an incorrect plate or a "Not Found" error due to savedirt, shadows, or a complex plate background, simply reposition your camera to exclude any small text and Tap and Hold to try the read.scan again.

In the below picture, the camera captured the text at the top of the plate, in this case the state, Indiana.
