Dash Cam microSD Capacity Estimator
Estimate recording retention and compare endurance-card options before buying storage.
Storage estimate
Approximate loop window: 38 hours
This is an estimate from usable card capacity and total recording bitrate. Treat it as a planning number, then verify the camera manual and real retention after installation.
- Camera load
- Dual-channel
- Bitrate
- Typical
- Useful days
- 4+ days
Use this estimate
- This is a reasonable starting size for many daily loop-recording setups.
- Reserve space for locked event clips and camera file overhead.
- Check real loop retention after one normal week of driving.
Change settings if
- Mixed driving and parked clips need both capacity and a regular card-health check.
- Lower bitrate if retention matters more than maximum plate detail.
- Use impact-only parking clips if motion clips overwhelm useful footage.
Card care
- Buy endurance-style microSD cards, not generic storage cards.
- Format cards in the dash cam when the manual recommends it.
- Replace cards that show write errors, missing clips, or repeated corruption.
Product recommendations
Products to compare for this result
The output recommends endurance-style cards because loop recording constantly overwrites storage.

How it works
Choose the recording quality, camera count, card size, and recording pattern. The estimator uses those answers in the browser to approximate loop time and the kind of card to buy.
Logic
- Retention is estimated from card capacity and total bitrate.
- Actual results vary by codec, resolution, event clips, and camera overhead.
- Always check the dash cam manual for supported card sizes.
- More parked recording means the same card overwrites useful footage sooner.
