For AUDI A4 9.2-inch 1080P digital coaxial signal electronic rearview mirror recorder
definition
The indirect field of view device that obtains a specified field of view through a system composed of cameras and monitors includes high-definition cameras, digital visual processing systems, security systems, LCD displays, and other electronic devices. It is a new type of rearview mirror that can replace traditional optical rearview mirrors.
advantage
A broader perspective. The field of view of traditional rearview mirrors is limited by the structure and angle of the vehicle, and the images that car owners can see are often limited. Electronic rearview mirrors are generally designed with a main lens and a wide-angle lens, which present images through a display screen, providing a wider field of view, eliminating blind spots, helping drivers better understand the surrounding environment, and reducing the occurrence of accidents.
Reduce the impact of adverse weather conditions. On rainy days, ordinary rearview mirror lenses are easily wetted by rainwater, and due to the temperature difference between inside and outside the car, the windows are prone to fogging. Electronic rearview mirrors can effectively avoid this problem. Electronic rearview mirrors usually have special waterproof shapes and coatings, which can reduce the adhesion of water stains and mud.
Night vision optimization. Electronic rearview mirrors can improve nighttime visual effects by enhancing image brightness and contrast, allowing drivers to observe the situation behind them more clearly while driving at night. At the same time, the glare problem caused by turning on high beam in the rear car can also be optimized.
Reduce fuel consumption. The use of electronic rearview mirrors can also help reduce fuel consumption. Due to the optimization of air resistance, fuel consumption can be reduced.
Enhanced additional features. Electronic rearview mirrors can also have other additional functions, such as automatically adjusting brightness, displaying navigation information, displaying warnings from driving assistance systems, etc., to improve driving convenience
