Motion Detection vs Time-Lapse Recording — Which is Better?

When your car is parked, your dash cam becomes your silent security guard. But not all parking modes work the same. The two most popular options are Motion Detection Recording and Time-Lapse Recording — and both come with different benefits.

So, which one is better for long-term parking surveillance? Let’s break it down.

What is Motion Detection Recording?
This mode triggers the dash cam to start recording only when it detects movement in its field of view (e.g. someone walking past, a car approaching).

✅ Pros:
Saves storage space — only records important activity

Saves power — ideal for battery-powered or OBD-II hardwiring

Easy to review — fewer clips, mostly relevant motion

❌ Cons:
May miss quick events — slight delay before recording starts

False triggers — e.g. moving tree shadows or lights

Gaps in recording — not continuous

What is Time-Lapse Recording?
This mode records continuously, but at a lower frame rate (e.g. 1 frame per second), creating a fast-forward effect while saving space.

✅ Pros:
Continuous coverage — captures everything, no gaps

Good for evidence — helpful in hit-and-run or vandalism

Predictable footage — easy to track incidents over time

❌ Cons:
Uses more storage — though still lower than full-frame recording

Harder to spot small events — due to fewer frames

Higher power draw — may affect car battery if parked long-term

 

Final Verdict:

If you want to save power and storage, and park in a low-risk area, go with Motion Detection.

If your car is in a public place or high-risk zone, Time-Lapse is better because it captures everything, even subtle incidents like door dings or key scratches.
