# Import a Recognizer

OpenText may provide recognizers that you can use with Media Server to run object class recognition. These are pre-trained, and to use one you only need to import the training data into your Media Server database. For a list of the available pre-trained recognizers, see Object Class Recognizers.

To import a recognizer

1. Go to the support portal and download the pre-trained models package. Ensure the version matches the version of Media Server that you are using.

2. Extract the pre-trained recognizer that you want to use.

3. Import the training data by running the action `ImportObjectClassRecognizer`, for example if you extracted the file to the folder `pretrained`, in the Media Server installation folder:

       /action=ImportObjectClassRecognizer&recognizer=surveillance
               &recognizerpath=./pretrained/ObjectClassRecognizer_Large_Surveillance.dat

   where,

   `recognizer` | The name to give to the imported recognizer.
   `recognizerpath` | The path of the recognizer data file on disk
   `recognizerdata` | The recognizer data (you can set this as an alternative to `recognizerpath`).

   Media Server imports the data. You can now run object class recognition.
