Using the correct type and specification of memory card is crucial to ensure reliable and continuous recording.

The type of SD card you need for your dash cam depends on the dash cam's specifications and your recording preferences.

While most dash cams use microSD cards due to their compact size, some models use standard-sized SD cards.

It's essential to check the product specifications and the user manual for your specific dash cam to determine which type of memory card it requires.

Additionally, the manual will provide recommendations on the class, capacity, and other specifications that are compatible with your particular dash cam model.

Here are the key factors to consider when selecting an SD card for a dash cam:

1. Check the Dash Cam's Manual: The best place to start is by reviewing your dash cam's user manual. It often provides specific recommendations for compatible SD cards. The manufacturer will suggest the class, capacity, and other details that are suitable for your particular model.

2. Consider Your Recording Needs: Determine how you plan to use your dash cam. If you want to record in high-definition or 4K resolution, you'll need a card with a higher class rating and more significant storage capacity. If you only need basic video recording, a lower capacity card may suffice.

3. Class Rating: As a general guideline, use a Class 10 or UHS-I card. This ensures that the SD card has a minimum write speed suitable for recording video without interruptions. If your dash cam supports higher resolution recording, you might want to consider UHS-II cards for even faster write speeds.

4. Capacity: Choose a card with an appropriate capacity for your recording needs. If you want to save a lot of footage before offloading it, a higher-capacity card (e.g., 64GB, 128GB, or 256GB) is a good choice. Smaller capacities, like 32GB, may be suitable for shorter recording periods.

5. Endurance Rating: For the longevity of the SD card, especially if your dash cam records continuously, consider an endurance-rated SD card. These cards are designed to withstand the frequent write cycles of dash cam usage.

6. Temperature Resistance: Dash cams are often exposed to a wide range of temperatures. Choose an SD card that is rated for extended temperature ranges, ensuring it operates reliably in various weather conditions.

Remember that using the wrong SD card can lead to issues like lost or corrupted footage, recording interruptions, and reduced card lifespan. Therefore, it's crucial to follow the manufacturer's recommendations and choose an SD card that aligns with your dash cam's capabilities and your recording preferences.
