FingerTec Face ID 4 series, is one of the sought after and powerful facial recognition terminals from FingerTec. Facial recognition verification is an easy method, however in some situations, the terminal might have trouble detecting faces. 

In this article, we will be sharing with you some tips to ensure the terminal can detect faces for the verification process. 

Step 1: Determine the Installation Location

• It is important to make sure the FaceID 4/4D terminal is installed at indoor area

• Avoid installing the terminals in locations that have contact with strong light source (e.g direct sunlight, spotlight, fluorescent light, etc);

• Avoid installing the terminals in locations with high moisture or condensation levels in the air. 

• The recommended installation height of the terminal from the ground to the camera is 1.2 meter.

• Please stand 0.5 meter away from the device during verification.
  
  

Step 2: Check the Infrared Camera 

To know the condition of the infrared face scanner, you need to run a face test. The FaceID 4/4D will display 2 images of your face: Colour display and infrared. Make sure both cameras capture and show your face image. Look at the infrared camera capture image, make sure it is a square in the middle of the screen; you have to look into the camera. If you can see your image in the square, the camera is working fine. Check the quality status bar to adjust to the best capture image. 

If you find that only one image shows on the screen that means only one side of the camera is working. Please send your Face ID terminal for checking. 

Please follow the steps below to change this setting;

Menu > Auto Test > Test Face

Step 3:  Setting Threshold

Threshold is a level of infrared scanner’s sensitivity. Threshold determines how many percent of your face is being read by the system. The higher the threshold level, the more percentage is being read, the more restricted the system. Configure the threshold for 1:1 and 1:N methods. 

For 1:1, the range is from 0-99 and the recommended value is 75.

For 1:N, the range is from 0-99 and the recommended value is 72. 

Please follow the Step below to change this setting;

Menu > System > Face > 1:1 Threshold/1:N Threshold > Input your value > Save

Camera Exposure 

You can adjust the light exposure level of infrared cameras in the FaceID 4 /4D. Improper value to the settings could affect the performance of the camera. The recommended value is 300. 

Please follow the Step below to change this setting;

Menu > System > Face > Exposure > Input your value > Save 

Adjusting Image Quality 

To determine the quality of face images captured by the FaceID 4/4D cameras during enrolment and verification, you can adjust the quality - the recommended value is 80.

Please follow the Step below to change this setting;

Press Menu > System > Face > Quality > Input your value > Save

Step 4: Check the Hardware

The final step is to check the hardware cover. After being used for a long time the camera cover might become scratched and the camera will become dusty. This will cause low camera performance and make it difficult to detect faces.
