# OutputIdentities

The types of identities to include in the output. Set this parameter to one of the following values:

- `All` - The output includes both recognized and unrecognized faces. In this case Media Server produces at least one record for each face that it attempted to recognize. Face recognition produces multiple records for the same face when there are multiple matches that exceed the RecognitionThreshold and MaxRecognitionResults is greater than 1. If a face is not recognized, Media Server outputs a single record with an empty `identity` field.
- `Known` - Include only recognized faces in the output. Face recognition produces multiple records for the same face when there are multiple matches that exceed the RecognitionThreshold and MaxRecognitionResults is greater than 1. If a face is not recognized, Media Server does not output a record for that face.
- `Unknown` - Include only unrecognized faces in the output. You might use this option to identify intruders in a building, where the database contains individuals who are expected to be present. In this case all records in the output will have an empty `identity` field.

TIP: You can customize the threshold at which faces are recognized by setting the parameter RecognitionThreshold.
