What kind of memory card is used for dash cams?

[DiJason]

Currently, the vast majority of dash cams use Micro-SD cards, originally named Trans-flash-Card (TF card), which is a member of the SD-Card Association. Due to their small size, fast transfer speed, and support for hot-swapping, they are widely used in mobile phones, navigation devices, and some automotive electronic products. The dimensions are only 15x11x1mm. Additional information is as follows: 1. How loop recording works: The video footage from dash cams is stored on removable memory cards. Videos are typically segmented into 1, 3, or 5-minute clips based on user settings. When the memory card is nearly full, the dash cam automatically deletes the oldest clip to store newly recorded videos, preventing storage shortages. 2. TF card: The memory card used in dash cams is also called a TF card, short for Trans-flash-Card. It supports hot-swapping, can be rewritten repeatedly, offers fast storage speeds, and is compact in size. These advantages make it widely used in various electronic devices for data storage. It is particularly suitable for the frequent read-write operations of dash cams, enabling the loop recording function. Depending on the size of the memory card, it can continuously loop and store recorded video footage.

I've been using a dash cam for several years and found the memory card is crucial. I recommend microSD cards with around 64GB capacity - perfect for most situations, allowing several days of loop recording. Choose high-speed cards like UHS-I to ensure smooth HD recording without lag or dropped frames. I use SanDisk High Endurance cards which are shockproof and heat-resistant, durable enough for vehicle vibrations. Avoid regular phone cards - they're not durable and prone to failure. Once I cheaped out with a 16GB low-speed card, resulting in choppy footage that missed critical evidence. Remember to format the card monthly to prevent malfunctions when full. Too large capacity is expensive, too small can't store enough; too slow speed causes recording issues. 128GB suits 4K, but 64GB suffices for 1080P. Investing in quality cards is worthwhile for road safety and peace of mind. Reliable brands like Samsung EVO are good choices - never buy no-name brands or you'll regret it.

From a technical perspective, dash cams require microSD type memory cards with high-speed specifications like UHS Speed Class U3. This ensures fast writing speeds and stable recording of high-definition videos without interruption. A minimum capacity of 32GB is required, with 64GB being a more balanced choice. I personally prefer SanDisk's High Endurance series, which is specifically designed for automotive environments. The card should be shockproof and temperature-resistant due to vehicle vibrations during driving. Slow cards may cause dropped frames and stuttering in recordings, while insufficient capacity risks missing critical footage. Loop recording relies on the card automatically overwriting old files. Regular card health checks using specialized software tools are recommended to prevent errors. Brands like Kingston also offer quality cards. Avoid repurposing old phone cards as they're prone to failure. Larger capacities like 128GB are suitable for long trips, but verify your dash cam's compatibility first. High-speed cards ensure all-weather reliability.

In my experience with automotive-related matters, it's essential to use high-speed microSD cards for dash cams. A 64GB capacity is ideal, ensuring fast read/write speeds for smooth video recording. Opt for professional shockproof cards like Sandisk High Endurance. The harsh in-car environment demands heat-resistant and vibration-proof cards. Avoid extremely cheap or oversized capacity cards, as some dash cams have compatibility limitations that may cause issues. Regularly format the card to prevent malfunctions. Since card quality directly affects evidence integrity, I recommend purchasing reputable brands to mitigate risks.
