How to Choose a Dash Cam?
2 Answers
Here are the selection methods for choosing a dash cam: 1. Lens: Glass lenses are better than resin lenses. 2. Chip: The main chip of a dash cam is the Ambarella A7 series. 3. Image sensor: The parameters of image sensors are often exaggerated. Currently, the mainstream image sensors are the OV4689 and AR0330. The OV4689 is generally used in higher-end products and is usually paired with the A70, making it the best top-tier configuration available. 4. A 32GB memory card is most suitable. Below is additional information: 1. Dash cam: It is an instrument that records images, sounds, and other related information during vehicle travel. 2. Function: The main role of a dash cam is to record the entire process of driving, including video and sound, providing evidence for traffic accidents. It also records time, speed, and location in the video, functioning like a black box. 3. Fraudulent claims: With fraudulent claims becoming increasingly rampant today, dash cams are particularly important.
When choosing a dash cam, I prioritize core features like video quality and field of view. High-definition resolutions such as 1080p or 2K ensure clearer footage, making license plates visible even at night—crucial for providing solid evidence in case of an accident. A wider field of view, like 140 degrees or more, captures adjacent lanes, leaving no detail missed. Night vision is also essential, as dimly lit roads often see unexpected incidents. Opt for models with loop recording, which automatically overwrites old files, sparing you the hassle of constantly managing the memory card. I once tried a brand with poor video quality—footage was blurry even in tunnels. Spending extra on a high-quality model is worth it. In short, don’t just go for the cheapest option; a good one lasts years and proves invaluable in critical moments.
