Do I Need to Install an Additional Dash Cam If My Car Comes with One Built-in?
3 Answers
If your car comes with a built-in dash cam, there is no need to install an additional one. However, if the built-in dash cam's performance is unsatisfactory, you can install an extra one later. Additional information is as follows: A dash cam is a device that records images, sounds, and other relevant information during vehicle travel. After installation, it can record the entire driving process, including video and audio, providing evidence for determining liability in traffic accidents. Dash cams are mainly divided into two categories: portable dash cams and aftermarket in-dash DVD-integrated dash cams. Portable dash cams can be further categorized into rearview mirror dash cams and data dash cams, which are characterized by good concealment, easy installation, detachability, low cost, and simple operation. On the other hand, aftermarket in-dash DVD-integrated dash cams are usually vehicle-specific and can be divided into front-installed and rear-installed types. Installing this type of dash cam is more costly and challenging, but it helps maintain the aesthetics of the car's interior.
Whether you need to install an additional dash cam alongside the factory-installed one depends on its functionality. Many OEM dash cams are convenient as they come pre-installed, but their lens angles may be narrow—for example, only capturing the front view, which might miss crucial details in a rear-end collision. Nighttime recording quality can also be mediocre, making license plates hard to read in low light. Limited storage is another issue; some models require manual video exports, risking loss of critical evidence in an accident. If you frequently drive long distances or navigate complex road conditions, upgrading to a model with a rear camera can expand coverage and enhance safety. Many cost-effective aftermarket dash cams are easy to install, but first test your factory unit—if it meets your needs, there’s no need to spend extra. Overall, try the built-in cam for a few days to evaluate its performance before deciding.
I've been using the factory-installed dash cam in my own car for three years. It's sufficient for daily commutes, but I once encountered a dispute where the footage was too blurry and the other party refused to admit fault. After that incident, I added a rearview camera, and now the recordings are much clearer both front and rear. The night vision feature is truly important, as the original camera couldn't capture details well in poor lighting conditions at night. Additionally, the storage card capacity is small, and the factory settings might overwrite old files after just a few days of loop recording, making it troublesome to retrieve evidence after an accident. Whether to install one depends on personal habits. If you frequently drive on highways or park in crowded areas, adding an extra dash cam can provide more peace of mind. When choosing, consider brand reliability and installation position to avoid obstructing your view. If you're on a tight budget, there are good options in the second-hand market. In short, safety comes first—don't skimp on small expenses.
