What kind of memory card should I buy for a dash cam?
2 Answers
Dash cams generally use TF cards or SD cards. Here are the relevant details: 1. Difference: TF cards are small cards primarily used in mobile phones; SD cards are larger cards typically used in portable devices like digital cameras. 2. Location: For rearview mirror dash cams, the memory card slot is usually on the top of the device body. For hidden or compact dash cams, the slot is generally located on the sides of the device. 3. Regular inspection: Depending on usage patterns, an authentic high-speed memory card should be checked every 3-6 months to determine if replacement is needed.
I often help friends choose memory cards for dash cams, and I think there are a few key points to focus on. First, opt for high-endurance cards, like SanDisk High Endurance or Kingston's Endurance series, which are specifically designed for dash cams and can handle frequent read-write cycles—regular SD cards tend to burn out quickly. Storage capacity is also crucial; I find 64GB works well for me, recording over 10 hours of HD footage. If you frequently drive long distances, 128GB is safer, but check your dash cam's maximum supported capacity. The speed class should be at least Class 10 or UHS-I to ensure smooth data writing without lag. Also, stick to reputable brands and avoid cheap knockoffs—I once used a low-quality card, and within months, all the data was lost, including footage of a parking collision. It's best to check the card's health annually and back up important files. Lastly, remember to format the card in the dash cam before installation to ensure system compatibility.
