What type of memory card is generally used in dash cams?
2 Answers
Dash cams use TF or SD memory cards. TF cards are small cards mainly used in mobile phones, while SD cards are larger cards typically used in portable devices such as digital cameras. The memory card slot in dash cams is mostly located on the top of the device. For hidden or smaller dash cams, the memory card slot is usually on the sides of the device. A dash cam is a device that records images, sounds, and other related information during vehicle travel. It captures high-definition footage, recording the vehicle's travel images, sounds, and driving data comprehensively. It mainly consists of a host, speed sensor, data analysis software, and an infrared camera. The functions of a dash cam include protecting the driver's legal rights to avoid extortion; providing accurate evidence for court trials in road traffic accident cases, ensuring precise sentencing and compensation; assisting traffic police in handling accidents quickly and accurately; and reminding drivers to avoid violations, thereby reducing accident rates.
Dash cams mostly use microSD cards, and both SDHC or SDXC types will work. Having driven for over a decade, I've encountered memory card issues a few times. The key is to get a fast enough card – Class 10 or UHS-I U3 is required for smooth high-definition video recording, otherwise frames may drop. Capacity should start from at least 32GB, with 128GB being more suitable to allow loop recording and avoid wasted space. Brands like SanDisk High Endurance are good, specifically designed for high-temperature environments – I haven't had any problems since switching. Also pay attention to slot compatibility; check the manual to confirm maximum supported capacity before buying. Remember to format the card every few months to extend its lifespan and prevent critical data loss, ensuring better driving safety.
