Product Functions

The 70mai HD Backup Camera is used as an accessory for 70mai in-car products and needs to be used with a main device.

After the backup camera is installed and connected with the main device correctly, the backup camera can capture and transfer the image from the rear of the vehicle to the main device for displaying the backup image or storing the image of the rear of the vehicle.

The 70mai HD Backup Camera is powered by the main device. When the main device starts operation, the backup camera will also be turned on automatically. When the main device is turned off or sleeps, the backup camera will also be turned off automatically.

Usage

• The main device powers the backup camera only when the main device receives power from an external power source. The main device cannot power the backup camera if it is not powered by the external power source.
• The image acquired by the backup camera is stored in the microSD card of the main device automatically. As the storage limit is reached for the microSD card, the earliest front-recorded and rear-recorded images will be overwritten by the latest images and deleted in turn cyclically.
• After the signal wire of the backup light is connected correctly, the main device will be switched to display the screen with backup image automatically when the vehicle is put in reverse gear. When the vehicle exits reverse gear, the main device will be switched back to the previous interface automatically.
