Car mounted DVR (digital video recorder) is a device that records road video clips while you are driving. The video captured by on-board DVR can be used for various purposes, including proving fault in a car accident or providing evidence to insurance companies. In this article, we will discuss the working principle, characteristics and advantages of in vehicle DVRs, as well as their use in daily driving.

Car mounted DVR is a small device installed on the dashboard of a car, usually close to the windshield. It has a lens aimed at the road ahead, which can capture video clips of the road while the driver is driving. It typically uses an SD card to store video clips, and some models are connected to smartphone applications that allow users to view and download clips.

There are various types of in car DVRs on the market. Some models continuously record videos while the car is in motion, while others only record videos while the car is in motion. Many models also have functions such as motion detection, which starts recording when the camera detects motion or sudden bumps, as well as loop recording. Once the SD card is full, it will overwrite the old lens.

The main benefit of in car DVRs is that they provide a visual record of events that occur during car journeys. This is useful in many situations, such as proving innocence in a car accident, capturing evidence of road rage or dangerous driving, or simply capturing beautiful scenery during scenic driving. Another benefit of in car DVRs is that they can help drivers better understand their driving and improve their skills. By examining the lens of their own driving, drivers can identify areas for improvement, such as speeding, sudden braking, or distracted driving.

Vehicle DVRs are also useful for fleet management as they provide a visual record of the company's vehicle driving style. This helps monitor driver behavior, track fuel efficiency, and identify potential maintenance problems.

In addition to the advantages of driving safety and management, in car driving recorders are also increasingly favored by car enthusiasts, used to capture high-speed driving, racing or off-road images. Many models are equipped with high-quality lenses that can capture videos at high resolution and frame rate, making them perfect for this purpose.
