Can a Dash Cam See Inside the Car?
2 Answers
A dash cam cannot see inside the car. It is only responsible for recording the road conditions in front of the vehicle. Some dash cams also have the capability to record both front and rear views. However, whether it's a single-lens or dual-lens dash cam, none can see or record the interior of the car. Single-lens dash cams have fewer components, are easier to install, and are more practical. Dual-lens dash cams, on the other hand, add a rear camera to the single-lens setup, enabling front and rear recording. Dual-lens dash cams have more components, are more complex to install, and have a higher failure rate. If using a dual-lens dash cam that can function as a streaming rearview mirror, the significant distortion from the rear camera can easily mislead the driver into misjudging distances, posing certain safety risks.
I usually enjoy tinkering with car equipment. Recently, while researching dash cams, I found that most models have their lenses directly facing the front windshield, mainly capturing the road outside to prevent accident disputes, with little to no view of the car interior. Unless it's a wide-angle model or has built-in auxiliary lenses—like some night-vision car cameras with slightly tilted angles that might inadvertently record the passenger seat, but with poor and blurry image quality. There are also dual-lens versions with front and rear cameras, where the rear camera might capture activities of children in the back seat, but if installed too far forward, it becomes ineffective. So, if you really want to monitor the car interior, you need to opt for a professional camera kit, additionally fixed on the sunroof or seats. Regular dash cams just won’t cut it—don’t waste your effort trying.
