Best Dash Cam with Loop Recording for Cars & Trucks

Best Dash Cam with Loop Recording for Cars

The loop recording function of dash cams allows for uninterrupted recording without manually clearing the SD card: when the SD card is full, the device automatically deletes the oldest unlocked videos to free up space. The recorded clips are usually short segments of 1–5 minutes. The advantage is that critical events are not missed, but important videos not locked in time may be deleted. Excessive locked videos, SD card issues, or improper settings can also cause this feature to fail. Users should remember to save or back up important videos in a timely manner.

What Exactly Is Loop Recording?

1.1 What Is Loop Recording?

Loop recording is an automatic overwrite storage mechanism. The dash cam splits video into small segments (usually 1, 3, or 5 minutes) and continuously writes them to a storage card (like an SD card). When the card is nearly full, the system automatically overwrites the earliest recorded segments, ensuring the latest videos are always saved without manually deleting old files.

1.2 What Factors Affect Dash Cam Recording Duration?

Recording duration depends on storage card capacityand video resolution. For example:

①　1080P resolution + 3-minute segments:A 32GB SD card can store approximately 5–6 hours of video.

②　4K resolution + 5-minute segments:The same capacity may only store 2–3 hours of video.

Due to limited storage space, loop recordingbecomes a core technology to ensure key videos are not lost.

1.3 Why Is Loop Recording Especially Important for Truck Drivers?

For semi-trucks, cargo trucks, and long-haul vehicles, driving times are longer and road conditions more complex, increasing the likelihood of accidents or disputes. Loop recordingensures that every stage of a long journey is continuously recorded, preventing important evidence from being missed due to manual storage management.
