Tevian SDK 2.12.1 is installed in Face Intellect version 8.0 and 8.1. If Face Intellect 8.0 or 8.1 was installed over the previous version, then Tevian SDK 2.12.1 will be installed instead of the current one. When upgrading to version 8.2.0.652 and higher, SDK Tevian 20221215_r2 is installed. 

To select the Tevian SDK to be used, do the following:

1. Go to the settings panel of the Tevian recognition module object.
   

2. From the Version drop-down list (1), select the required Tevian SDK version.

   When you change the SDK version, the re-generation of biometric vectors will automatically start (for details, see Switching between the face recognition modules and SDK versions). In Face Intellect 8.0 and higher version, when you select the SDK version, all possible versions will be displayed, even if they are not installed. To ensure the correct operation, it is necessary to select one of the installed SDK versions.

   
   

3. Click the Apply button (2).

You can see the current version of Tevian SDK in the Version/Vector size (bytes) field in the Statistics tab of the Face recognition and search interface module (see Displaying the statistics).
