What does loop recording mean for a dash cam?
2 Answers
Loop recording for a dash cam refers to the continuous video recording function of the device. Modern dash cams are equipped with memory cards, typically ranging from 4GB to 32GB in capacity. As the dash cam records in loop mode, the saved videos accumulate, gradually occupying the memory card's space. When the memory card reaches full capacity, the loop recording feature automatically deletes the oldest recorded videos (those furthest from the current time) to free up space. This ensures the continuous operation of the loop recording function, allowing the dash cam to store the most recent video footage.
I did some research on loop recording when I installed my dash cam before. Simply put, it's a feature that automatically overwrites old footage when storage is full, allowing the device to run 24/7. My dash cam is set to record 3-minute clips, and the memory card can store about 2-3 days of content. Without this feature, you'd either have to manually delete videos or risk sudden storage failure stopping recordings – my friend once missed capturing a crash-for-cash scam because of this. Now I use a 128GB high-speed card with 1080P resolution, which works perfectly – no missed recordings and no daily cleanup hassle. Remember to manually format the memory card every six months to prevent lagging and file errors.
