What Is Loop Recording On a Dash Cam?

Loop recording on a dash cam is a feature that allows the camera to record continuously without running out of storage space.

Here’s how it works:

  • The dash cam saves videos in small segments (e.g., 1, 3, or 5 minutes).
  • When the memory card gets full, the camera automatically overwrites the oldest files with new recordings.
  • This ensures you always have the most recent footage without needing to manually delete old files.

Key Points About Loop Recording

  • Never stops recording – it ensures uninterrupted video capture.
  • Protects important files – most dash cams lock event footage (like collisions triggered by G-sensor) so it won’t get overwritten.
  • Segmented clips – makes it easier to find specific incidents rather than scrolling through one long video.

Advantages of Loop Recording

  • Uninterrupted Video Capture: Loop recording keeps your dash cam rolling nonstop, so every moment on the road is documented without gaps.
  • Smart Use of Memory: Forget about constantly clearing storage—old clips are replaced automatically, making room for new footage.
  • Secure Key Moments: If something important happens, you can lock the file so it won’t be erased, guaranteeing vital evidence stays protected.

Example

If your dash cam is set to 3-minute loops and has a 32GB card:

  • It records multiple 3-minute videos until the card is full.
  • Once full, the dash cam starts recording over the oldest 3-minute clip, keeping storage fresh.

In short: Loop recording = continuous recording with automatic overwriting of old footage.

How to Set Up Loop Recording

Here’s a clear and practical guide on how to properly set up loop recording on a dash cam:

1. Insert and Format the SD Card

  • Use a high-quality, high-endurance SD card (recommended by your dash cam manufacturer).
  • Format the card inside the dash cam before first use to ensure compatibility.
  • Some dash cams require regular formatting (every 2–4 weeks) to prevent file corruption.

2. Enable Loop Recording in the Settings

  • Go to your dash cam’s menu or settings.
  • Look for “Loop Recording” or “Recording Length.”
  • Choose a video segment length (commonly 1, 3, or 5 minutes).
    • Shorter segments (1–3 min): Easier to find specific clips.
    • Longer segments (5–10 min): Fewer files, slightly smoother review.

3. Adjust File Protection Options

  • Make sure G-sensor (impact detection) is turned on. This will automatically lock files during collisions so they aren’t overwritten.
  • Learn how to manually lock a video (usually by pressing a button on the dash cam) in case you want to save something important.

4. Test the Overwriting Feature

  • Let your dash cam record until the card is full.
  • Check that the camera correctly overwrites the oldest clips with new ones while keeping locked files safe.

5. Fine-Tune for Your Needs

  • Daily drivers: A 3-minute loop is usually best.
  • Long trips: A 5-minute loop gives fewer but longer clips.
  • Fleet or business use: Adjust based on storage size and monitoring needs.

Pro Tips

  • Always use Class 10 / UHS-I or higher microSD cards for smooth recording.
  • If your dash cam has an app, check whether loop settings can be customized there.
  • Replace SD cards every 12–18 months if used heavily—they wear out over time.
