Buying Guide: Key Considerations For Dash Cam Micro SD Cards
When choosing a microSD card for dash cams, focus on endurance, capacity, and write performance. Consider your climate, the number of cameras, and how often you review footage. High-endurance cards are designed to handle continuous recording without excessive wear. Capacity should align with how long you need to store footage between offloads.
- Endurance vs. capacity: High endurance is essential for continuous recording; larger capacity reduces the need to swap cards frequently.
- Write speed: Look for UHS Speed Class 3 (U3) and Video Speed Class if available, especially for 4K footage.
- Device compatibility: Confirm the card is formatted for exFAT and supported by your dash cam’s firmware and file system.
- Environmental resilience: Shocks, temperature, and moisture tolerance help ensure reliability in vehicles.
- Backup strategy: For multi-camera setups, using two cards or redundant storage can prevent data loss.
