Inventory of Car Models with Built in Driving Recorders and Analysis of Difference between DVR and Black Box​

DVR (Digital Video Recorder) focuses on video and audio recording. It is like the "eyes" of the vehicle, capturing the road conditions ahead, the dynamics of surrounding vehicles, pedestrian behavior, and the driver's operation details in real-time through on-board lenses. Its storage method mostly relies on external memory cards, and car owners can replay, copy or transmit the recorded content at any time. After a traffic accident, the video data recorded by DVR can intuitively restore the scene, becoming an important basis for liability determination and greatly reducing the difficulty of dispute handling.​

Black box focuses more on recording vehicle operation data, which can be called the "data log" of the car. It mainly collects key parameters during vehicle driving, including real-time speed, acceleration changes, braking frequency, engine speed, steering angle and other core data. These data are stored in the dedicated storage module inside the device, which has high security and stability and is difficult to be tampered with artificially. The main application scenarios of the black box are concentrated in accident in-depth analysis, vehicle performance evaluation and insurance claim investigation, providing accurate and objective data support for professionals to explore the cause of the accident.​

In short, DVR is an "image recorder" and black box is a "data recorder". Although both serve driving safety, their functional focuses are completely different.​

Popular Car Models Equipped with Built-in Dashcams​

Tesla Model 3/Y: Intelligent Linked Recording System​

Tesla's Model 3 and Model Y are equipped with a built-in dashcam system called "TeslaCam". It makes full use of multiple cameras around the vehicle to build a 360-degree monitoring range, which can record the dynamics around the vehicle in an all-round way. When the vehicle detects abnormal events such as collision and sudden braking, the system will automatically save the relevant video clips, and the owner can also perform emergency recording through manual operation. The recorded video needs to be stored in a USB device inserted into the car, which is convenient for the owner to view at any time and extract evidence quickly when needed.​

BMW 3 Series: Clear Recording in High Definition and Low Light​

The built-in dashcam of the new BMW 3 Series adopts a front and rear dual-lens design, which can record the road conditions in front of and behind the vehicle at the same time. Its high-definition lens has excellent light-sensing ability, and can clearly capture details such as road signs and license plate numbers even in low-light environments such as dusk and night. More intimately, car with built in dashcam is seamlessly connected with the in-vehicle infotainment system, so the owner can easily view and manage the recorded video files directly on the central control screen without additional equipment, which greatly improves the operation convenience.​

Mercedes-Benz C-Class: Intelligent Device for Parking Safety​

In addition to the basic driving recording function, the built-in dashcam of Mercedes-Benz C-Class also has two practical features: loop recording and motion detection. The loop recording function can automatically overwrite the earlier video content to ensure sufficient storage space; The motion detection function protects the vehicle when it is parked. When it detects collisions, abnormal movements and other situations around the vehicle, the device will automatically start recording immediately, effectively preventing accidents such as scratches and theft of the vehicle, and solving the worries of car owners after parking.​

BYD Han: All-round and Dead Angle-free Monitoring​

At the same time, it is also connected with BYD's DiLink intelligent network connection system. Car owners can control the start/stop, photographing and other operations of the recorder through voice commands, further improving the convenience of use.​

With its perfect integration with the vehicle, convenient operation and practical functions, the built-in car driving video recorder has become an important consideration for more and more car owners when purchasing a car. And clarifying the difference between DVR and black box can make us more clearly understand the value of different vehicle-mounted recording devices, so as to better use them to protect driving safety. With the continuous development of automobile technology, it is believed that the function of built-in dashcam will be more perfect, bringing more comprehensive safety protection for car owners.
