Electronic Rearview Cameranitor Systems, CMS), a system composed of cameras and monitors, is designed to provide clear rear and side views within a specified field of vision. It is a new type of indirect vision aid, referred to as the "Camera-Monitor System" (camera-mo) by the new GB15084 standard.The "CMS (Camera Monitoring System)" provides an electronic rearview mirror. The advantages of the electronic rearview mirror include overcoming the limitations of traditional optical rearview mirrors, which are constrained by factors such as curvature, shape, size, and angles. This results in a significantly smaller blind spot, a wider field of view, and allows drivers to see more details, enhancing safety during driving.
