DMS Calibration


    Why do we need calibration?

    To utilize AI-based DMS features, a calibration should precede the operation of the DMS feature. The calibration process is intended to improve the accuracy of driver recognition since the driver’s physical condition (height and eye size), and driving position vary from person to person. 


    1. Complete the installation of the DMS camera and the Front camera.
    2. Turn on the engine, and allow the DMS to boot up.
    3. Adjust the camera angle if necessary to ensure the driver’s head is within the camera viewing range. (Please check your face through “Live view” via Wi-Fi direct or BlackVue Cloud)
    4. When the DMS calibration starts, the Blue LED blinks for 30 secs to 2 mins.
    5. When the DMS calibration is completed, the Green LED turns on.
    6. When the DMS is enabled, the device can recognize the Driver’s behavior (e.g. Drowsy, Distracted, Hand Distraction, Mask)

    • During the calibration process, the DMS camera is recording. 
    • Every time the DMS camera starts, calibration operates. and it can re-calibrate automatically while driving.
