Can a Dash Cam Capture Rear-End Collisions?

Can a Dash Cam Capture Rear-End Collisions? A dash cam can indeed capture rear-end collisions. Here are the selection criteria for dash cams: 1. Lens: Glass lenses are superior to resin lenses. Additionally, using a dual-lens setup can capture footage of the rear of the vehicle. 2. Chip: The primary chip in dash cams is the Ambarella A7 series. 3. Image Sensor: Image sensor specifications are often exaggerated. Currently, the mainstream image sensors are the OV4689 and AR0330OV4689, typically used in higher-end products. Paired with the A70 chip, this configuration represents the top-tier setup available. 4. A 32GB memory card is the most suitable capacity.
Last time my car got its rear bumper scratched in a supermarket parking lot, I immediately checked the dashcam footage, but it captured nothing. Since dashcams are usually installed on the front windshield with the lens facing forward, the rear of the car is completely a blind spot. Unless your car is equipped with a dual-camera dashcam (front and rear) or has a separate rear window camera, it's very difficult to capture what happens behind you. That time, I had to accept my bad luck, and later I simply installed a rear camera. Now when parking, I habitually position the rear of my car towards surveillance cameras or choose parking spots with more empty spaces on both sides. If you do get scratched, don't panic—first check if nearby stores have surveillance footage that can be retrieved. If all else fails, just handle it through insurance.
