EZVIZ Smart MicroSD Card D Series 64GB

The EZVIZ D Series is a 64GB microSD card made for security cameras, dashcams and DVRs rather than for occasional photo storage. Surveillance recording never stops, so the card is built to absorb the constant loop-writing that wears out an ordinary memory card. It is a 64GB microSDXC card rated Class 10 and UHS-I U3, with read speeds up to 90MB/s and write speeds up to 50MB/s — ahead of what a high-definition camera stream demands, and quick enough to pull footage off the card when you need to review an incident. The card is waterproof, shockproof and X-ray proof, and it operates from 0°C to 70°C, which matters inside a housing on a rooftop or on a car dashboard. Physically it is the standard 15 x 11 x 1mm microSD footprint. This is the card to fit in a home or shop CCTV camera that records around the clock, in a dashcam that starts writing the moment the engine turns over, or in a small DVR handling several channels at once. It also works normally in phones, tablets and action cameras, though its real strength is endurance under continuous recording rather than occasional burst photography.
