What to look for in an SD card for a security camera

1. Storage Capacity

The storage capacity you need depends on how often your security camera records. For continuous recording, a higher capacity card (64GB or 128GB) is recommended.

2. Speed Class

The speed class of an SD card refers to its minimum sustained writing speed. For high-resolution video recording, a high-speed class (Class 10, UHS-1) is essential.

3. Endurance

Security cameras write and overwrite data continuously, which can wear out an SD card over time. Look for cards specifically designed for surveillance or dash cams, as they often have higher endurance.

4. Reliability and Brand Reputation

Choose a reliable brand that offers warranty protection. This ensures that you have support if the card fails or encounters any issues.
