Face recognition is used to locate and determine facial similarities detected by the system. Images for face recognition are registered in a face library, by the user, and accessed using a face recognition smart search tool that is built into the DVR. Please note, the DVR can support a max of 2 face detection & recognition channels. For more information on how to use these options please refer to the information provided below.

Step 3: Click on the Database option located in the AI mode menu and click on Face Database Config. Click Add to begin registering images and create a face library. Enter a name for your face library and click OK. The library will now be saved to the database. Click on the Details section to begin adding images into the library.
