Prepare for dashcam road-facing ADAS calibration

In order to get started with road-facing advanced driver-assistance system (ADAS) features, which gather information about the road ahead and detect tailgating events, your dashcams first need to be calibrated. Calibration ensures the accuracy and quality of triggered events. The road-facing ADAS calibration process for almost any device on the market demands precision and a bit of extra time than other calibration processes might.  

For the Surfsight® dashcam, the calibration process is dynamic. This requires recording several measurements related to vehicle size and the position of the installed dashcam, and then driving the vehicle on the highway for approximately 5 minutes before beginning configuration.

To enable road-facing ADAS, you'll need a few measurements that can be taken ahead of time. Record these measurements in centimeters or inches:

• the dashcam height from the ground (Figure 1, “Dashcam height from the ground”)

• the width of the rear axle from the outer edges of each tire (Figure 2, “Rear axle width from the outer edges of each tire”)

• the dashcam offset from the center of the windshield, measured from inside the cabin (road-facing view) (Figure 3, “Dashcam offset from the center of the windshield”)

  • when the dashcam is to the right of the center of the windshield - enter a negative measurement

  • when the dashcam is to the left of the center of the windshield - enter a positive measurement

Important

The dashcam should first be installed at least 1.6 meters (160 centimeters/5.249 feet/62.99 inches) above the ground before beginning ADAS calibration. This is mandatory.
