Abstract
A video recording apparatus with a pre-event circulation recording function is provided. A limitation on memory capacity may be removed by recording a pre-event video directly on a nonvolatile storage medium, such as a hard disk drive (HDD), without using a buffer according to a circulation recording method during pre-event recording performed to record videos before and after an event occurs.
