How to use

Mount the front camera on the windshield and position the interior camera to cover the cabin area according to manufacturer alignment guides. Insert the provided 128GB SD card into the camera’s card slot and power the device from the vehicle’s 12V outlet or a hardwired power source. Configure recording settings through the camera interface or companion app to enable simultaneous 4K front and interior recording, set loop intervals, and adjust exposure or sensitivity for night use. The camera will begin recording automatically when power is supplied and will manage storage by overwriting the oldest files when the card is full.

Recommendations

For reliable operation, format the included SD card in the camera before first use and periodically check recorded files. Place the interior camera to avoid obstructing driver vision while maintaining a clear view of passengers. When using the dash cam for professional or rideshare purposes, review local laws regarding audio and video recording to ensure compliance.
