Built for 24/7 video recording

SanDisk Video microSDXC cards are engineered for continuous capture in security cameras and dash cameras. The 128 GB capacity supports extended loops of footage without frequent swaps. Elevated endurance reduces the need for regular storage maintenance in always-on edge devices.

Class 10 and U1 ratings guarantee minimum write

Sustained 20 MB/s write performance meets the demands of constant video streams. Read speeds up to 100 MB/s allow quick offload when reviewing footage. Card health monitoring in compatible cameras provides early warnings before storage fails.

Standard microSD form factor fits most cameras

Insert the card into any device with a microSDXC slot; no drivers or software are required. Ensure the host supports the UHS-I bus to reach rated speeds. Buyers who need capacities beyond 1.5 TB or write speeds above 20 MB/s should consider alternative storage solutions.
