For BMW IX3 9.2-inch 1080P digital high-definition coaxial electronic rearview mirror front and rear dual recorders
definition
Electronic Rearview Mirror (ERM) is a new type of rearview mirror. Unlike traditional mechanical rearview mirrors, it reflects the rear image on the LCD screen installed inside the car through a high-definition camera installed on the exterior of the rear of the car, thus achieving the purpose of observing traffic conditions behind.
1. It can expand the visual range, reduce blind spots, and improve driving safety. Especially when driving at night, it can effectively avoid glare caused by the high beam of the rear car, protecting the driver's vision.
2. Electronic rearview mirrors are less affected by the environment and can provide drivers with clear rearview images in adverse weather conditions. For example, when driving on rainy days, rainwater can make the windows and exterior mirrors blurry, affecting visibility. However, electronic rearview mirrors are not affected by this and can maintain clear images.
3. Electronic rearview mirrors can also reduce the vehicle's wind resistance and improve its performance. Especially for new energy vehicles, reducing wind resistance means increasing range.
