What type of memory card is used in dash cams?
2 Answers
The memory card used in dash cams is either TF or SD type. TF cards are small cards primarily used in mobile phones, while SD cards are larger cards commonly used in portable devices such as digital cameras. A dash cam is an instrument that records images, sounds, and other related information during vehicle travel. After installing a dash cam, it can record the entire driving process in video and audio, providing evidence in case of traffic accidents. The dash cam continuously records while driving, capturing time, speed, and location in the footage. It can also be used at home as a DV to film daily life or as a home surveillance device, and it can serve as a parking monitor. Generally, a dash cam consists of a main unit, a speed sensor, data analysis software, and an infrared camera.
When it comes to dash cam memory card types, I know the most commonly used are microSD cards, specifically microSDHC or microSDXC formats, depending on your device's compatibility. I recommend choosing fast cards like Class 10 or UHS-1 grade to ensure smooth video recording without lag. For capacity, 32GB is a good starting point to store more driving records, but I'd suggest going straight for 64GB to avoid frequent overwriting of old files. Installation is simple—just insert it into the card slot—but be careful not to buy counterfeit cards, as data loss could compromise accident evidence. Compatibility is also crucial; check the manual to confirm the card speed matches your device. I've seen friends experience missing frames due to slow cards. Regularly formatting the card can extend its lifespan, which is key for long-term use.
