What does loop recording mean on a dash cam?

[DeEmerson]

Loop recording on a dash cam refers to the continuous video recording function of the device. Current dash cams are equipped with memory cards, typically ranging from 4GB to 32GB in capacity. As the dash cam keeps recording in loop mode, the saved videos will continuously increase, gradually occupying the memory card's storage space. When the memory card becomes full, the dash cam's loop recording feature will automatically delete the older recorded videos that are further from the current time, thereby freeing up space to maintain continuous operation of the loop recording function and store new video footage.
