This function on a dashboard camera allows for continuous video recording. The device records in segments, typically ranging from one to five minutes in length. When the storage medium reaches its capacity, the oldest segment is overwritten by the newest, creating a continuous cycle of recording.
The primary benefit of this capability is that the dashcam is always recording without the need for manual intervention to clear storage. This ensures crucial events are captured, even if memory card space is limited. Its development addressed the challenge of finite storage in early recording devices, guaranteeing that the most recent events are always documented.
