From v.2.9.5 of BioStar 2, the function "Enroll Profile Photo & Visual Face Using a Webcam" has been introduced.

With this new function, the user can add a photo taken by a webcam connected to a PC to be used as a user's profile or a visual face credential.

Note that 

Visual Face Credentials created with photos taken with a PC webcam are only compatible with FaceStation F2 and BioStation 3 devices. 

Expectation effectiveness

This new function is expected to be helpful in sites where enrolling the visual face credential through the devices is difficult.

• BioStar 2 recommends using Google Chrome version 75 or higher. 
• This feature can only be used to [HTTPS], and it does not support HTTP. Please make sure BioStar 2 Setting is enabled with HTTPS.

2. You can also upload a photo from your PC to enroll by clicking Upload photo. However, you need to be cautious about the below items.

• The supported image file size is up to 10MB. 
• Supported image file formats are JPG, JPEG, and PNG. 
• After clicking Take Photo, it may take a few seconds for the photo to be taken.

Precautions

You need to be cautious about the below items when enrolling a visual face by using a webcam.

• Maintain a reasonable distance from the webcam. 
• Enroll your face straight ahead without moving. 
• Do not change the user's facial expression. 
• Do not enroll a face while the user is wearing masks, hats, or eye patches. 
• Do not enroll a face with the user raising their head or bowing.

the "Image Registration" pop-up.

Then, bring your face to the webcam and click "Take photo".
