What size memory card is needed for a dash cam?

[LeMalachi]

Generally, a dash cam requires a 16GB or 32GB memory card. If you need to record more videos or require higher resolution, a 64GB or larger card is recommended. Common memory card capacities available in the market for dash cams include 8GB, 16GB, 32GB, and 64GB. Key considerations when selecting a dash cam: video resolution and recording mode. Video resolution: When choosing a dash cam, the first thing to consider is its video resolution. It should be able to clearly capture pedestrians' faces or vehicle license plate numbers. Typically, a 1080P resolution is sufficient. Lower resolutions may produce overly blurry footage with limited value, while excessively high resolutions consume too much storage space, leading to frequent memory card replacements and unnecessary hassle. Recording mode: In addition to resolution, it's important to select a dash cam with loop recording. When the memory card is full and not replaced in time due to oversight, critical incidents may go unrecorded. A dash cam with loop recording can overwrite old footage with new recordings when the memory card is full, ensuring no potential event is missed.
