i-PRO WV-SDA128G 128GB SDXC Memory Card for Surveillance
The i-PRO WV-SDA128G is a professional-grade 128GB SDXC memory card engineered for edge-based video storage in i-PRO IP cameras and compatible surveillance devices. Built on 3D TLC NAND flash, this card delivers onboard recording capacity—roughly 4–8 weeks of continuous HD video depending on bitrate—without requiring frequent offloads or centralized NVR infrastructure. That matters in remote deployments, field locations, or redundancy scenarios where local storage keeps your video safe even if network connectivity drops.
Key Features
- 128GB capacity: Stores approximately 4–8 weeks of continuous HD recording at typical bitrates. In field deployments, this eliminates the need for daily card swaps. On your main NVR, it acts as a failover tier—if centralized storage goes offline, the camera continues recording locally without losing frames.
- V30 Video Speed Class: Guarantees a minimum sustained write speed of 30 MB/s, critical for uninterrupted 24/7 recording. Most consumer SD cards throttle under sustained write load; V30 ensures your camera won't drop frames or corrupt recordings during peak demand, even across multiple simultaneous streams.
- 50 MB/s write / 100 MB/s read speeds: Write speed is the real bottleneck in surveillance. At 50 MB/s sustained, this card handles 1080p and higher resolutions without speed-induced bottlenecks. Read speed matters when exporting footage for forensic review or pulling video clips off the card at full throughput.
- Class 10, UHS Speed Class U3: Class 10 ensures sustained minimum performance under any load condition. UHS-I support lets you hit the full 100 MB/s read speed on camera motherboards that support it. Combined with V30, this prevents the card itself from becoming a throughput ceiling in your surveillance system.
- 3D TLC NAND technology: Triple-level cell NAND is more durable than SLC in write-heavy, always-on workloads like continuous surveillance. 3D stacking improves reliability and density; you get more storage without sacrificing endurance in this compact form factor.
- 3000 rewrite cycles (reference): Industry standard for NAND flash durability. In a 24/7 recording scenario with typical bitrates, this translates to 3–5 years of reliable service before proactive replacement is prudent. Plan replacement as a preventive maintenance item in high-duty deployments.
- Operating temperature range -25°C to +85°C (-13°F to +185°F): Covers outdoor street-level, unheated utility boxes, and climate-controlled indoor installations. The -25°C floor handles frozen environments and sealed outdoor enclosures without performance loss. The +85°C ceiling accommodates sealed camera housings or direct sunlight exposure without derating.
Integration & Compatibility
The WV-SDA128G (often searched as WV SDA128G) is tested and certified for all i-PRO network cameras with SD card slots. Before purchase, verify your specific camera model supports SDXC (not just SD or SDHC)—older devices may not recognize the full 128GB capacity or may cap at 32GB. The card requires an SD UHS-I host controller in the camera to deliver the full 100 MB/s read speed; legacy SD interfaces will still record but at reduced read speeds during export. Compatible with standard card readers and forensic imaging tools for chain-of-custody workflows. When integrating with network video recorders or storage planning, treat the WV-SDA128G as a local retention layer that supplements your centralized NVR, not a replacement for it. Pair with your standard offload and archival procedures.
Deployment Considerations
Deploy this card in remote or mobile surveillance where network bandwidth is constrained, NVR space is unavailable, or you need a failover tier for business continuity. It's particularly valuable in outdoor or extreme-environment installations where the -25°C to +85°C range prevents performance loss that consumer-grade cards might experience. At 1080p@30fps, 128GB fills in roughly 10–14 days depending on motion and compression; plan offload and rotation schedules accordingly. For multi-camera deployments, calculate total retention needs across all cards and establish a card-cycling protocol. In high-duty scenarios (continuous 24/7 recording across multiple cameras), replace cards every 3–5 years proactively to avoid unexpected NAND wear-out.
Frequently Asked Questions
Q: Will the WV-SDA128G work in my i-PRO camera that supports SDHC?
A: SDHC cameras can physically read SDXC cards, but they typically recognize only 32GB of the 128GB capacity. Check your camera's documentation for SDXC support before relying on the full 128GB; contact the camera manufacturer if in doubt.
Q: How long will 128GB store continuous video?
A: Retention depends on resolution, bitrate, and compression. At 1080p@30fps with typical H.264 compression, expect 10–14 days of continuous recording. H.265 codec (if supported by your camera) extends retention by roughly 40–50%. Calculate your specific scenario by dividing 128GB by your camera's expected bitrate.
Q: Can I use the WV-SDA128G as my only storage (no NVR)?
A: Yes, for remote single-camera deployments or as a failover tier. But for multi-camera systems or long-term archival, pair it with centralized NVR storage. The card is best used as a local backup layer, not a sole retention mechanism.
Q: Does the WV-SDA128G support 4K recording?
A: The card supports any resolution your camera outputs—4K, 1080p, or lower. 4K bitrates are higher, so 128GB fills faster. Expect 5–7 days at 4K continuous recording, depending on compression and frame rate.
Q: What's the warranty on the WV-SDA128G?
A: Refer to i-PRO's standard product warranty terms. As a storage component, coverage may differ from camera warranties. Contact the distributor or i-PRO for specific warranty details and return procedures.
Q: Will the card work in extreme heat or cold?
A: Yes. The -25°C to +85°C operating range covers outdoor, unheated, and sealed-enclosure deployments. Consumer cards often derate or fail outside 0°C to 60°C; this card is rated for industrial and harsh environments.

The WV-SDA128G is a solid edge-storage choice for i-PRO camera deployments where network reliability or NVR capacity is a constraint. The 50 MB/s sustained write speed and V30 guarantee are what separate this from consumer alternatives—your camera won't throttle or drop frames under continuous load. The -25°C to +85°C operating range is a genuine differentiator for outdoor and extreme-environment work, where garden-variety cards fail or derate.
Technical Highlights:
- V30 Video Speed Class with 50 MB/s write: Guarantees 30 MB/s minimum sustained—you won't hit the write-speed wall that consumer cards do. At 50 MB/s actual sustained write, you can safely record 1080p+ multi-stream scenarios without frame loss or file corruption.
- 100 MB/s read speed (UHS-I): Matters less for recording, but critical when pulling footage for export or forensic imaging. You're moving 100GB+ off the card without waiting hours; on legacy SD interfaces, this drops to ~25 MB/s, so verify camera UHS-I support if throughput is a priority.
- 3D TLC NAND with 3000 rewrite cycles: TLC is more wear-tolerant than SLC in continuous-write workloads. 3000 cycles translates to 3–5 years in 24/7 scenarios at typical bitrates. Plan replacement as preventive maintenance, not emergency response—flash wear is cumulative and unpredictable near end-of-life.
- Operating temperature -25°C to +85°C: Your outdoor boxes won't degrade the card. Sealed enclosures and direct sun can push internal temps to 70–80°C; this card handles it without performance loss. Most consumer cards spec to 60°C; you're getting 25°C of margin here.
Deployment Considerations:
- Capacity math: At 1080p@30fps H.264, plan for 10–14 days of continuous storage. If you're recording high-bitrate or 4K, retention drops to 5–7 days. Calculate your offload schedule now—waiting until the card is full is a recipe for overwrite and lost evidence.
- SDXC backward compatibility gotcha: Verify your camera supports SDXC, not just SDHC. Older i-PRO models may physically accept the card but cap recognition at 32GB. Check your camera firmware version and model datasheet; a firmware update may unlock full capacity support.
- UHS-I vs legacy SD speed gap: If your camera has only a standard SD (not UHS-I) controller, reads will max out at ~25 MB/s instead of 100 MB/s. Writes still hit 50 MB/s for recording, but export/forensic workflows get slower. This isn't a dealbreaker for continuous recording, but it's a workflow penalty you should know.
The WV-SDA128G fits three use cases well: redundancy tier on your main NVR (camera keeps recording if centralized storage fails), sole storage in remote single-camera deployments, and long-term retention in harsh or extreme-temperature environments. Don't use it as your only archival mechanism—pair it with NVR or cloud backup. For multi-camera systems with high bitrates, calculate total card fleet costs and rotation schedule upfront.
