How many hours of recording time can my dashcam provide?

What Determines Recording Time

The total recording time on a microSD card depends on several key factors:

1. Video resolution – higher resolutions (e.g., 2K or 4K) create larger video files.
2. Bitrate – higher bitrates capture more detail but use more storage.
3. Frame rate – higher FPS increases file size.
4. Number of channels – front, rear, or cabin cameras multiply storage use.
5. Compression format – H.265 (HEVC) uses space more efficiently than H.264.

 General Recording Time Patterns

• As resolution and bitrate increase, total recording time decreases.
• Single-channel dashcams record significantly longer than dual- or triple-channel systems.
• Higher-capacity SD cards extend recording loops before older footage is overwritten.
• Using H.265 compression can increase recording time compared to H.264 at the same quality.

 Why It Matters

• Ensures your dashcam retains enough recent footage before overwriting.
• Helps you choose the right SD card size for your recording quality and setup.
• Balances video clarity with storage duration depending on how the dashcam is configured.
