4 Adjust the camera position. There is a mask on 

the view of the DMS camera. The installer should 

keep adjusting the camera position to make the 

driver image fit in the mask. When the mask turned 

into green, the position of the DMS camera can be 

regarded as correct.

5 Let the driver maintain the driving position and 

look forward, tap "Calib and Look Forward". Wait 

for 3 seconds until "Calibration is done" is heard 

from the camera.

6. Install and calibrate the DMS module

Waylens recommends using a high endurance microSD card (class 10 or higher MLC microSD card 

32-256GB) designed for continuous recording situations. While other cards will work with the 

Secure4K, they are much more prone to card errors and failures.

Some Secure4K dock has a SD card cover to prevent the unauthorized access to the microSD card. 

In that case please first loose the screw and the camera body. 

You’re all set!
