What is the purpose of a dash cam?

[AubreyMarie]

The purpose of a dash cam is to provide drivers with strong evidence in the event of sudden traffic accidents. It can quickly, truthfully, and accurately use video footage to assist traffic police in handling accidents fairly, justly, and reasonably. Below are some considerations when selecting a dash cam: Camera Angle: Most dash cams have a camera angle of around 100 degrees, which is generally sufficient to capture the lanes on both sides of the vehicle. Video Resolution: A video resolution of 1280X720 can usually ensure that details like the license plate of the car in front are clearly visible. The light sensitivity of the dash cam's CMOS chip and the quality of the external lens glass directly affect its nighttime recording performance. Memory Capacity: Opt for a memory card with as large a capacity as possible to ensure smoother video recording and better compatibility with the storage card.
