1. Activate ADAS:
connect network, via WIFI or a 3G/4G SIM card (the device needs to be turned off when inserting a SIM card), and then reboot the device by long pressing the power button, there will be ADAS icon on the right.
2. Calibrate ADAS
ADAS can only work when driving on road with lines.

  • adjust the horizontal line to the end of road, the vertical line to the middle of car hood, then press okay.
  • adjust the lane lines to two sides of DVR screen. It takes 1-3 minutes to start ADAS.

Video reference

3. ADAS needs clear lane lines on the road. If the lane lines are blurred, or it's dark at night, it won't work properly.

 

Is my DVR enough to replace the SD card with a larger memory on its own?

Junsun's DVR supports SD cards up to 64GB. If your SD card is larger than 64GB, it may cause the DVR to stall or be damaged.
