Calculating Your Storage Needs:
Key factors influencing storage requirements include:
- Cameras & Resolution: More cameras, higher resolution = more data.
- Frame Rate & Compression: Higher FPS, less efficient compression = more storage.
- Recording Mode: Continuous recording consumes more than motion-triggered.
- Retention Period: How long you need to keep footage.
A Dahua 32 Channel NVR 4 dyski twarde configuration is a game-changer for data retention, ensuring critical moments are always recorded and accessible.
RAID Configurations for Data Security
Many Dahua NVRs with multiple drive bays support RAID (Redundant Array of Independent Disks). Configurations like RAID1 or RAID5 protect your footage against single hard drive failures, ensuring data integrity and minimizing downtime – invaluable for mission-critical surveillance.
Advanced Features of Dahua 32 Channel NVRs
Dahua integrates cutting-edge technology into its NVRs. A Dahua 32 Channel NVR with 4 Hard Drives typically includes:

Estimated Recording Days Based on Configuration
To illustrate the storage power of a Dahua NVR with 4 hard drives, here’s an example of estimated recording days for a single camera, scaled for 32 cameras. Actual results may vary based on scene complexity, compression, and specific camera settings.
| Camera Resolution | Frame Rate (FPS) | Compression (H.265+) | Storage per Camera/Day (Approx.) | Approx. Days for 4x10TB HDDs (32 Cameras) |
|---|---|---|---|---|
| 2MP (1080p) | 15 | Enabled | ~15-20 GB | ~60-80 Days |
| 4MP | 15 | Enabled | ~25-30 GB | ~35-45 Days |
| 8MP (4K) | 15 | Enabled | ~40-50 GB | ~20-25 Days |
* Estimates based on average motion activity and efficient H.265+ compression. Total usable storage considers RAID overhead if applicable. For continuous recording, these numbers might be slightly lower.
