This system transmits the captured footage to the integrated device, allowing the driver to intuitively perceive obstacles and pedestrians. This feature significantly reduces the risk of accidents such as scraping, collisions, and other incidents. Additionally, the product records all driving footage, serving as crucial evidence in case of an accident.
