Can a Dash Cam See Scratches on the Side of the Car?

Whether a dash cam can see scratches on the side of the car depends on the type of dash cam. Here are the details: 1. Single-lens dash cam: Cannot see the sides, only the front. 2. Dual-lens dash cam: Can see both the front and rear, but still cannot see the sides. 3. If you want to see the sides: You need to install a 360-degree panoramic dash cam to observe whether there are scratches on the sides of the car. Below is a brief introduction to the 360-degree panoramic dash cam: The 360-degree panoramic dash cam uses four ultra-wide-angle cameras installed at the front, rear, left, and right of the car to simultaneously capture images around the vehicle. After processing and stitching by image software, it forms a 360-degree top-down view of the vehicle's surroundings.

Here's what I think. Dash cams mainly capture the front view of the car, with limited coverage on the sides. My car has privacy window film, and last week I found a scratch on the right rear door. Checking the dash cam footage, it didn’t capture the offending vehicle at all. Unless you install a multi-camera system, like ride-hailing drivers who add small cameras under the side mirrors, but who would go to such lengths for a regular family car? If you really want to prevent side scrapes, just buy a pair of blind-spot convex mirrors from Taobao and stick them on your side mirrors—it’s a 20-yuan solution, much more practical than fussing with dash cams.

Mr. Zhang, a ride-hailing driver, told me that he had to install three cameras in his car just to barely capture the side views. While a standard 170-degree wide-angle dash cam sounds impressive, it only incidentally captures side views. The other day, my car's wheel got scraped in an underground mall parking lot, and all the dash cam footage showed was a shadow flashing by. The main issue is that most dash cams automatically go into sleep mode when parked, requiring additional parking monitor wiring for continuous recording, but battery drain becomes another concern. If you're worried about scratches, it's best to park under surveillance cameras. If that's not possible, investing in a full-car PPF (paint protection film), though expensive, really does protect against scratches.

From personal experience, it's really difficult. Once, the right front door of my car was scratched by a delivery tricycle, and my dashcam, which claims to have a 150-degree wide-angle, only captured a glimpse of the other vehicle's handlebar. Later, a friend in auto repair explained that dashcam lenses have a fisheye effect, with more severe distortion towards the edges of the frame, making license plates hard to read. For effective side monitoring, it's better to follow the approach of some high-end cars and integrate cameras directly into the side mirrors. By the way, if you do get scratched, remember to report it to the police within 24 hours to check the parking lot surveillance—it's more reliable than relying on the dashcam.

Just ran into this issue! Yesterday when I picked up my car, I found scratches on the left rear fender. I was eagerly looking forward to checking the dashcam footage, only to discover that the side view was completely distorted. After some research, I learned that the wider the dashcam's angle, the worse the edge image quality becomes. The auto parts store owner said unless I install a panoramic imaging system, but modifications would involve altering the wiring, affecting the warranty. My makeshift solution now is: when parking in a narrow spot, I adjust the dashcam angle towards the driver's side, but there's nothing I can do about the passenger side. By the way, a reminder: installing a separate side camera might violate traffic regulations by obstructing the view, so be cautious.

As a seasoned driver with ten years of experience, I can confidently say that capturing side views with front-mounted dashcams is largely a matter of luck. Last year, my car's side mirror was scratched by an electric scooter ridden by a parent near a school gate. The footage from my so-called 165-degree wide-angle dashcam showed the side mirror barely at the edge of the frame, stretched like putty. Subsequent tests revealed that standing near the front wheel would often result in the camera failing to capture a clear view of a person's face. My advice? Prioritize protecting the front and rear of your car. Buying two inexpensive dashcams to face the side windows is a smarter choice than splurging on a full panoramic kit—saving you around two thousand. And remember, when temporarily parked roadside, simply rotating the dashcam 90 degrees to face your car door is the most practical move.
