You can set the viewing angles of both the road-facing and in-cabin-facing lenses.
To set the view angles:
Press the touchscreen of the AI-12 dashcam to wake it up.
Enter the default PIN 3333 to unlock the dashcam for the first time, or your own PIN subsequently.
See Set and manage your dashcam PIN if you need help with your PIN.
Press Live View.
Use the arrow keys to toggle between the road-facing and in-cabin-facing views.
Use the special screwdriver that was included in the box to loosen the three security screws on the round side of the dashcam. Do not remove the screws fully.
Adjust the viewing angle of the road-facing lens by rotating the body of the dashcam; then adjust the viewing angle of the in-cabin-facing lens by rotating the ring. Make sure all the viewing angles are set correctly.
Use Live View to position both the road-facing and in-cabin-facing lenses in the proper directions. Use the arrow keys to toggle between the views.
When a dashcam is in storage, the battery gets completely drained. Before using the dashcam, you need to charge it for an extended period of time, using at least a 2A power source, before the dashcam turns on.
Tighten the three side screws when finished.
