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.
