Surveillance SD & microSD Cards

Durability and Endurance in Surveillance Edge Units


Removable Solutions That You Can Trust To Work With Demanding Surveillance Workloads

The industrial SD and microSD™ cards and WD Purple microSD cards deliver superior endurance, reliability, and extended temperature range for smart video and surveillance applications such as IP cameras, mDVRs, dash cams, body cams and drones.

Designed and tested to withstand 24/7 continuous write workloads, meet data retention requirements, and accommodate harsh environmental conditions, the industrial SD and microSD cards and WD Purple microSD cards are ideal for low footprint, local storage at the surveillance edge, working in concert with other Western Digital solutions in on-premises DVRs and NVRs, in near-edge cloud servers and in back-end cloud data centers.

Serviceability and Flexibility of Storage at the Edge of an Imaging Ecosystem

Industrial SD and microSD cards and WD Purple microSD cards are a perfect match to the needs of a surveillance system. With high durability, small footprint, and features like host lock and health statistics through the card health monitor, these cards are used by multiple imaging devices to provide long lasting storage of video – either as a standalone solution, as local failover storage for an NVR, or as a companion to a cloud solution in a VSaaS system.

The cards can be part of the original design or be added to the edge device later – when the unit is already deployed in the field – by a service provider, an integrator or a value added reseller.
