Sentinel Cameras

A 64GB microSDXC card sized for continuous security-camera recording. It is V10 and A1 rated with a UHS-I interface, so it keeps writing steadily while a camera records in HD instead of dropping frames under sustained load — the failure mode that catches out cheap, unrated cards.

It is the storage we stock for The Guardian, and it works equally well in dash cams, drones, phones and action cameras.

Capacity: 64GB microSDXC (OLEO®)

Video speed class: V10 — rated for sustained HD video writing

App performance class: A1

Interface: UHS-I

Suits: security cameras, dash cams, drones, smartphones, action cameras

Footage stays on the card and in your hands — there is no cloud subscription attached to it. Format the card in the camera before first use, and replace it if recordings start failing, as you would with any card in continuous-write duty.
