What kind of card is used in a dash cam?
2 Answers
The card used in a dash cam is generally a TF card, while some models use SD cards. TF cards are small cards primarily used in mobile phones, whereas SD cards are larger and commonly used in portable devices like digital cameras. For rearview mirror dash cams, the memory card slot is usually located on the upper side of the device body. For hidden or compact dash cams, the memory card slot is typically found on either side of the device body. A dash cam is an instrument that records images, sounds, and other relevant information during vehicle travel. After installation, it can capture the entire driving process in video and audio, providing crucial evidence in the event of traffic accidents.
I've been driving for over a decade, and the memory card for dash cams is actually that compact Micro SD card. I've used several brands of car dash cams myself and found this type of card the most durable because it's small and doesn't take up space, plus it can withstand high temperatures and bumps inside the car. Usually, a 64GB capacity is quite suitable, storing several days of high-definition video. For long trips, 128GB is better to prevent overwriting old files mid-journey, which could compromise evidence. A crucial tip is to choose Class 10 or higher speed cards—don't go for low-speed ones, or the recording might stutter or drop frames. I once used a cheap card and suffered when the video was incomplete at a critical moment. I also recommend formatting the card every three months to extend its lifespan, while checking if the card slot is loose to ensure worry-free driving safety.
