For 4K video recordings, choose from 32 GB, 64 GB, or 128 GB based on your desired retention period and how frequently the camera records. A 32 GB card supports shorter recording periods, while 64 GB or 128 GB provides more local storage for longer retention, more frequent recording, or both.

For 4K video SD cards, look for a Class 10 speed class, U3 UHS speed class, and V30 video speed class, which support sustained write performance for high-resolution recording. Also confirm that the card matches the camera’s supported format and capacity, especially when using it for local video storage.

High-endurance 4K video SD cards are suitable for continuous recording in compatible cameras that support local onboard storage. Class 10, U3, and V30 ratings support recording up to 4K video, with storage capacities available from 32GB to 128GB.

Check your camera’s documentation for support for micro SD cards, the available capacity range, and the required video speed rating. For 4K recording, look for support for a Class 10, U3, or V30 card, then confirm that the card’s capacity, such as 32GB, 64GB, or 128GB, falls within the camera’s specifications.
