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

WD Purple microSD cards are a perfect match to the needs of your surveillance system. Designed for high durability and a small foot print, they are physically easy to protect, host-locked, and able to provide card health statistics for maintenance purposes (via compatible cameras). These cards are used by multiple imaging segments to locally store a stream of video as either a standalone solution, as part of an NVR architecture, or as a companion to a cloud solution in a Video-Surveillance-as-a-Service (VSaaS) system.

The cards can be a part of the original design, or be added later while the unit is already deployed in the field by the end user, a service provider, an integrator, or a value-added reseller.
