Axis 02021-021 Surveillance Card 256GB microSDXC 10-Pack
Overview
The Axis 02021-021 is a 10-pack of 256GB microSDXC cards engineered for continuous write-intensive video recording in Axis camera systems. Each card (model 02021-021) enables edge recording directly to the camera without dependency on centralized NVRs or network infrastructure — a critical advantage when network bandwidth is constrained or unavailable. The pack includes SD card adapters for legacy reader compatibility and standard SD slot devices.
Compatibility
These cards work with Axis camera models equipped with microSDXC card slots. Axis Zipstream technology, when enabled in compatible cameras, reduces file sizes on-card without quality loss — extending effective recording duration beyond the raw 256GB capacity. Exact compatible camera series depend on your specific model; verify your camera's manual for microSDXC support before ordering.
Deployment Considerations
Edge Recording Advantage: Each camera records independently to its card, eliminating single points of failure in centralized recording architectures. Footage is captured directly when network disruptions occur — no data loss during connectivity gaps. This is essential for retail branches, manufacturing floor zones, and remote sites where WAN reliability is inconsistent.
Health Monitoring: Axis cameras with microSDXC support include integrated card health status reporting. The system flags performance degradation or imminent failure early, allowing proactive card replacement before data loss occurs — a meaningful operational difference vs. passive storage.
Storage Math: 256GB per card at typical H.265 bitrates (with Zipstream compression) delivers 7–14 days of continuous 1080p recording depending on scene complexity and motion frequency. Higher-resolution cameras or disabled compression reduce retention proportionally; lower bitrates extend it.
Capacity Planning: 10 cards per pack provides flexible deployment: one card per 10-camera edge installation, or 5 pairs for redundancy across 5 sites. Each card carries its own health monitoring — no shared dependency.
