What type of card is inserted in a dash cam?

Dash cams use memory cards, as most dash cams do not come with built-in memory and rely on memory cards for storage expansion or portable digital hard drives. Choosing the memory card capacity: Selecting the appropriate memory card size for a dash cam depends on individual needs. For office workers, an 8GB-16GB memory card is usually sufficient. Firstly, 8GB and 16GB memory cards are moderately priced, offering good value for money. Selection based on dash cam usage: The choice of memory card size should be determined by the recording resolution of the dash cam and the storage requirements of the camera. High-definition dash cams typically record in 720p or 1080p. A 4GB card can record approximately 1 hour of 720p video, while 1080p video occupies nearly twice the storage space of 720p.

The card typically used in dash cams is a microSD card, which is that tiny memory card, the same type used in smartphones. Nowadays, dash cams are all digital HD devices, so they require a card that is both fast and stable. Personally, I use a microSD card, with capacities ranging from 32GB to 128GB being common. A 32GB card is sufficient to store several hours of video, but a 128GB card can last much longer, making it ideal for long-distance driving. The speed class of the card is crucial, such as Class 10 or UHS-I, to ensure smooth video recording without lag. If you use a slow card, large video files may easily get interrupted or even corrupted. In terms of brands, I recommend SanDisk or Samsung for their good compatibility and reliability. Installation is straightforward—just insert the card into the dash cam's slot—but remember to manually format it every three months to prevent loop recording failure when the card is full, which could lead to the loss of crucial accident evidence. When choosing a card, also consider the voltage; some cards with too low voltage can overheat severely, affecting the lifespan of the dash cam. In short, selecting a good card can make your dash cam more reliable and better protect your safety.

The dash cam in my car directly takes a microSD card, commonly known as the small SD card. You can easily buy this at supermarkets or electronics stores, with the capacity depending on your needs. I personally use a 64GB one, which is enough to record my daily commute videos for a week. The loop recording feature overwrites old files, so you don’t need to worry too much about running out of space. However, be careful not to buy cheap no-name brands—once I tried a card that cost just a few bucks, and it frequently froze, failing to record critical moments. Now I stick to mid-range SanDisk cards, which are fast and reliable. After inserting the card, don’t forget to test it to ensure the dash cam recognizes it properly. For maintenance, I recommend regularly checking the card’s health. When using a card reader to view files on your computer, delete unnecessary clips to prevent card failures. Also, check user reviews when choosing a card to avoid compatibility issues. These small details can ensure worry-free driving safety.

The memory card used in a dash cam is a microSD card, a small memory card. A capacity of 32GB or 64GB is recommended, which is sufficient for loop recording. When choosing a card, a medium speed like class 10 is fine—it's cost-effective and practical. From my experience, don't spend too much on the card; you can get one for just a few dozen yuan on Taobao, but make sure it's reliable to avoid losing critical data. For daily use, it automatically overwrites old files, so you don't need to replace the card frequently.
