This article explains the steps to calibrate the camera for better performance.
For better results, it is advisable that calibration is done on the location where the device is used or mounted.
Process
The first step is to make sure that the camera module is working.
1. Choose MENU
2. Choose Autotest
3. Choose Test Face
4. Make sure the camera module display a normal picture and an infrared picture
*If one or both don't display properly, there is a high possibility that the camera module is defective. Email FingerTec support at support@fingertec.com for assistance.
5. After testing the camera, choose Back to start the camera calibration mode.
6. Choose RTC Test
7. The device will show 00(s) : 0(ms)
8. Click on the screen and the time will run.
Wait until the time runs to 01(s) : ++(ms) and click one more time to stop it.
Repeat 3 times.
9. After done, choose Back
10. Choose Test Face
11. To confirm that the device is in the camera calibration mode, both displays are in black and white, and the screen has a Save icon on the top right corner
12. Place your face in front of the camera and place it according to the display box.
Do the step until the bar reaches 140 and above, and that the face displays have nearly the same size and display quality. Once this step is done, your camera is good to go.
13. After that choose the Save icon to save the calibration
