About the Integral INMSDX256G100V30-SEC

From our tech experts at CEN

The Integral Security High Endurance 256GB (INMSDX256G100V30-SEC) doubles the capacity of the 128GB card and its endurance rating, with up to 48,000 hours of continuous recording. It keeps the same UHS-I U3, V30 and A2 ratings, up to 100MB/s read and 50MB/s write, power-off protection, and an SD card reader in the box.

Who it suits

Drivers using 4K or multi-channel dash cams, or long parking mode sessions, and CCTV or home cameras that need more footage before overwriting. For a basic 1080p or single-camera setup, the 128GB card is usually enough. For maximum retention, there is a 512GB version.

Our tech experts advise

Not every camera accepts 256GB, so confirm the maximum card size in your manual first. Format the card in the device, and reformat it periodically to keep recording reliable. It is rated from -25°C to 85°C for in-car and outdoor use. Browse our Integral collection.
