What is the Difference Between Dual-Lens and Single-Lens Dash Cams?
2 Answers
The difference between dual-lens and single-lens dash cams lies in the fact that dual-lens dash cams have an additional rear-facing camera. Below is relevant information: 1. Recommendations: It is advisable to purchase a stable-performance single-lens dash cam. The original purpose of dash cams is to record the view in front of the vehicle while driving. The rear camera of dual-lens dash cams is not only troublesome to install but also provides poor image quality, with many being low-quality knockoffs. 2. Disadvantages of Dual-Lens Dash Cams: Dual-lens dash cams place higher demands on the processing power of the chip. The chip is the core component of a dash cam and also the most costly part. Dual-lens dash cams not only have inferior lens quality but also rely on cheap chips, which cannot guarantee stable operation.
I'm often asked about the difference between dual-lens and single-lens dash cams. As an experienced driver, safety always comes first for me. A single-lens dash cam only has one camera, which can only record the road conditions in front of the vehicle, providing incomplete evidence in cases of rear-end collisions or accidents. A dual-lens dash cam, on the other hand, has an additional camera, typically one recording the front and another recording the rear or interior of the vehicle, offering comprehensive coverage for more reliable accident documentation. For example, if you're rear-ended on the highway, a single-lens cam can only show your braking signs, while a dual-lens cam captures the entire movement of the vehicle behind you. Additionally, dual-lens cams perform better in parking surveillance, preventing unnoticed scratches. The downsides? Installation is a bit more complicated, requiring extra wiring for the rear camera, and it costs a few hundred yuan more. But from a safety perspective, it's worth it. I've been driving for decades and never skimp on this expense.
