# Enroll

The Enroll task adds images to your training database.

For example, you can run face recognition on a video stream and add all unrecognized faces (those with recognition confidence scores below a certain threshold) to the database.

NOTE: This task modifies the Media Server training database. To use this task, you must belong to an authorization role that allows the `Admin` standard role.

Configuration Parameter | Description
--- | ---
Database | The name of the database to add images to.
GPUDeviceID | The device ID of the GPU to use.
Identifier | The identifier to add images to.
ImageLabel | The label to use for an image that is added to the database (maximum 254 bytes).
Input | The track that contains the images to enroll.
Module | The module to enroll images for.
NumParallel | The maximum number of images to add to the database concurrently.
PostAction | Specifies what Media Server should do after enrolling an image in the database.
PostSyncDatabase | Specifies whether Media Server should synchronize with the training database after enrolling an image.
Type | The engine to use. Set this parameter to `Enroll`.

## Output Tracks

The following table describes the tracks that are generated by this engine. The Output column indicates whether the information contained in the track is included by default in the output created by an output task (when you don't set the `Input` parameter for the output task).

Output track | Type | Description | Output
--- | --- | --- | ---
`Result` | EnrollResult | Contains a record for every item added to the database. If an error occurred, the record describes the error. | Yes
`ResultWithSource` | EnrollResultAndImage | The same as the `Result` track, but each record also includes the source frame. | No
