This product is suitable for streaming media cameras on the left and right rearview mirrors of large vehicles. It is installed outside the front loading truck on both sides (at an angle of 70 degrees) instead of traditional left and right rearview mirrors. The all metal shell can also be used for blind spot detection (at an angle of 170 degrees), better solving the visual blind spots of large vehicles. Adjustable structural rotation has been added to the product itself, making it easier to adjust the angle for a wider visual experience and solving driving blind spots. The image adopts HDR image processing technology, and during driving, the rear headlights will automatically dim without exposure.
