What type of memory card is used in a car dash cam?
2 Answers
The memory card used in a car dash cam is either a TF or SD card. TF cards are small cards primarily used in mobile phones, while SD cards are larger cards commonly used in portable devices like digital cameras. Memory capacity of dash cams: Most dash cams do not have built-in memory and rely on memory card expansion or portable digital hard drives. For SD card expansion, capacities vary from 2GB, 4GB, 8GB, 16GB, to 32GB. For portable digital hard drives, capacities can range from 250GB, 500GB, to 1000GB, meeting users' greater video storage needs. Functions of dash cams: They feature identity recognition, recording car driving time, speed, and mileage, with functions for over-time driving (fatigue driving) alerts and recording. They also manage software, providing a good human-machine interface, enabling functions such as car information management, driver profile input, modification, query statistics, and report printing.
I've been using a dash cam for several years and found that the key is to choose a TF card, also known as a MicroSD card. This type of card is very small and fits perfectly when inserted into the back of the dash cam. It's best to opt for a high-speed card, the kind labeled U1 or Class10, otherwise, recording high-definition videos may lag. A capacity of 32GB is recommended as a starting point; my 64GB card can store about four to five days of footage. When buying a card, choose a durable one specifically designed for dash cams, as these can withstand high temperatures and vibrations. Never go for cheap, no-name brands—I bought a generic card before that failed twice in less than six months, which ended up being a waste of money. Regularly formatting the card can help it last longer.
