# PostAction

Specifies what Media Server should do after enrolling an image in the database.

- `None` - do nothing.
- `Build` - train Media Server using the new image.
- `BuildNull` - train Media Server using the new image and then remove the image data from the database.

Training Media Server to recognize a face means that the face can be recognized as soon as Media Server synchronizes with the database. If you are running face recognition on a video and enrolling unknown faces, building the enrolled faces can prevent Media Server adding duplicate entries to the database if the same face is detected again.
