The record contains the following information:

- `id` - a unique identifier for the recognized number plate. The number plate recognition engine issues an ID for each detected appearance of a number plate, and the records output from the vehicle make/model recognition engine use the same IDs as the input records.
- `grillepatch` - the region of the input image that was used for recognizing the vehicle make and model.

- `identity` - represents a match between the ingested media and a vehicle model in your training database. This element contains data only if you train Media Server to recognize vehicle models, you set the `Database` parameter when you configure the task, and a match is found. The following information is available:

  - `identifier` - the identifier of the recognized vehicle model.
  - `database` - the name of the database in which the vehicle model exists.
  - `confidence` - the confidence score for the match (from 0 to 100, where 100 is maximum confidence).
  - `metadata` - the metadata that you associated with the vehicle model when you trained Media Server. If there is no metadata in the training database, this element is omitted.
- `grillepercentage` - the percentage of the vehicle grille that was visible in the source image.
- `vehiclemake` - the recognized vehicle make.
- `vehiclemakescore` - the confidence score for vehicle make recognition, from 0 to 100, where 100 indicates maximum confidence.
- `region` - a bounding box that contains the entire vehicle.
- `regionscore` - the confidence score for the region (from 0 to 100, where 100 is maximum confidence).
- `vehicletype` - the vehicle type (`bus`, `car`, `motorcycle`, or `truck`).
- `vehicletypescore` - the confidence score for the vehicle type (from 0 to 100, where 100 is maximum confidence).
