Resolution affects video clarity - higher resolution means clearer footage. You can adjust the settings based on your needs. The main functions of a dash cam are: 1. Providing evidence: It records video and audio of the entire driving process, which can serve as evidence in traffic accidents. 2. Documenting road trips: Travel enthusiasts can use it to record their adventures, capturing the journey along with timestamps, speed, and location data - essentially functioning as a "black box". 3. Parking surveillance: The recorded footage must not be edited, as altered videos cannot assist in determining liability after an incident. This also helps prevent potential insurance fraud schemes that are unfortunately common in today's society.

I often help friends adjust their dash cams, and resolution settings are really a key point. Generally, it's recommended to set it to 1080p or 2K, which ensures clear image quality and captures license plate details while keeping file sizes manageable. If the memory card is large enough, like 128GB or more, you might try 4K—super sharp footage but very space-consuming, which can lead to faster file overwrites or heavy battery drain. For night recording, consider low-light performance, as higher resolutions might actually cause blur. From my experience, 2K is a good balance for daily driving, and there's no need to chase the highest resolution. Also, make sure loop recording is properly configured to avoid missing data. In short, adjust based on your car's usage frequency and memory card capacity to ensure critical footage is reliably saved.

I use my dash cam every day for commuting, and 1080p resolution is just perfect—simple and practical. The footage is clear enough to read road signs without hogging too much memory, so even a small-capacity SD card can handle loop recording. Some people chase after 4K for better image quality, only to find their storage filling up rapidly, risking interrupted recordings during trips. I've tried lower resolutions like 720p, but nighttime footage was so blurry it felt like driving blind. The setup is actually straightforward—just adjust it in the device menu, prioritizing clarity both day and night. Don’t forget to periodically check your SD card to clear old files, ensuring reliable driving safety.

For setting the resolution of a dash cam, I recommend going directly with 2K or 1080p. Anything lower won't capture license plates clearly, making it easy to miss accident evidence; higher resolutions like 4K consume too much power and storage, with little practical benefit. Choosing a balanced point is hassle-free and reliable.

I used to have a 720p dash cam, but the footage was too blurry to be used as evidence in an accident. Later, I upgraded to 2K resolution, and the video details were crystal clear, easily capturing license plate movements. No need to go for overly expensive high-end models—1080p is sufficient for daily protection. Regularly clearing the memory card to ensure enough space is a must; don’t let resolution issues cause trouble.
