What Type of Memory Card Should Be Used for a Dash Cam?
2 Answers
Dash cams should use memory cards with a capacity of 8GB or more, and must meet Class6 or higher standards. Below are the relevant details: Commonly used memory cards for dash cams: The commonly available memory card capacities on the market are 8GB, 16GB, and 32GB. Additionally, as a high-speed read/write device, dash cams have stringent requirements for storage and read speeds. It is essential to use a Class6 or higher memory card to ensure smooth video storage and prevent corrupted recordings. Loop recording mode: To avoid the dash cam's memory from being completely filled, most devices are set to loop recording mode. This means recordings are divided into multiple segments, where newer videos continuously overwrite the older ones.
Having driven for so many years, I'm very familiar with dash cams. For memory cards, reliable brands like SanDisk or Samsung's High Endurance series are the top choice, with a capacity of at least 32GB. Regular cards often stutter or interrupt critical footage when recording in HD, compromising safety evidence collection. It's best to opt for high-speed cards with Class 10 or above speed ratings to ensure every frame is clear and smooth. Don’t cheap out with low-quality cards—summer heat makes car interiors harsh, and these durable cards can withstand heat and vibration. Personally, I’ve experienced distorted recordings before, but after switching to a quality card, the issues disappeared. A 64GB capacity allows for several days of loop recording, eliminating the hassle of frequent card swaps. Also, check compatibility when purchasing—make sure your dash cam supports microSDXC to avoid return hassles. Safe driving relies on details, and investing a little extra is worth it.
