How to Use Face Recognition

Face recognition is used to locate and determine facial similarities detected by the system. Images are registered in a face library, by the user, and similarities are accessed using the face recognition smart search tool to display the similarities.

Note: The images must be in jpeg format when registering to a library. This option requires the use of a plugin to function if using a web browser. It is recommended to use Internet Explorer when setting up this function.

There are 2 methods of face recognition, common mode, and stranger mode. Common mode allows the device to use the images registered in the face library as a reference to recognize faces. Stranger mode will alert the system once an unrecognized face is detected. For more information on how to set up common mode, please refer to the information provided below. 

Step 1: Open a web browser and log into the web UI for your device. For more information on how to access the web UI, click here.

Step 2: Click on the AI option located in the main menu. Click on the Face Detection & Recognition option and click OK. Please note, if you are switching AI Modes the DVR will reboot. 

Step 3: In the Parameters section, click on Face Recognition. Click on the Enable option to activate the setting. 

Step 4: 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. 

Step 5: Click Register ID, enter the requested information, click the "+" option to add the image. Click OK. Click the "X" option to exit the details interface. 

Step 6: Navigate back to the Face Recognition menu in the Parameters section and click on the "+"  option to import the face library. Click OK. 

The similarity percentage will default to 80%. This will be the similarity threshold that the system will recognize the image. This percentage can be modified by clicking the gear wheel option under the parameters column. Please note, stranger alarm allows the system to alert once an unrecognized face is detected.

Step 7: Click OK to save the settings. 

Viewing Face Recognition Data 

All face recognition data retained by the system can be accessed using the Face Recognition option located in the Smart Search menu. A search by attributes or a search by picture can be performed.
