What is a dash cam memory card?
2 Answers
The memory card used in dash cams is either a TF or SD card. TF cards are smaller in size and primarily used in mobile phones, while SD cards are larger and typically utilized in digital cameras or portable devices. In dash cams, the memory card is usually inserted into the main body of the device, often in a hidden slot. For compact dash cam models, the memory card slot is commonly located on either side of the device. A dash cam is an instrument that records video, audio, and other relevant information during vehicle operation. It captures high-definition footage of the road ahead, along with sound recordings and vehicle status data. The system mainly consists of a main unit, speed sensor, data analysis software, and infrared camera.
The memory card in a dash cam is used to store driving footage, functioning like a small portable hard drive inserted into the camera to record all visuals. I've used both 32GB and 64GB cards—the 32GB can store about 3 hours of HD video, while the 64GB doubles that. I recommend choosing a U1-class high-speed card; otherwise, recording in 4K may lag. Also, don’t cheap out on no-name brands—I once tried a low-quality card that frequently auto-overwrote crucial footage, making it infuriating when trying to retrieve recordings at critical moments. Additionally, remember to format the card every two months to clear fragmentation, or it may crash when full. Some premium cards now support a wide temperature range from -25°C to 85°C, making startup much faster in winter.
