Hanwha XRN-6420DB4 64-Channel 8K NVR with 140TB Storage
The Hanwha XRN-6420DB4 is an enterprise-grade 64-channel 8K NVR built on 12th-generation Intel processors, purpose-built for large-scale surveillance deployments requiring massive storage capacity and sustained high-bandwidth recording. With 140TB raw storage across 16 SATA HDD bays and support for 32MP native resolution, this NVR delivers the performance and reliability demanded by mission-critical security infrastructure.
Key Features
- 64-channel recording with support up to 32MP camera resolution
- 140TB maximum raw storage capacity (16 SATA bays, up to 10TB per drive)
- 520 Mbps recording bandwidth in distributed mode; 300 Mbps in normal mode
- H.265, H.264, and MJPEG dual-stream compression options
- RAID 5/6 support with automatic hot-swap and N+1 failover redundancy
- Redundant power supply for uninterrupted operation
- Dual HDMI outputs (3840×2160@30Hz + 1920×1080@60Hz)
- Two-way audio support for integrated communication
- PoE compatibility for streamlined network deployments
Performance & Recording Specifications
The XRN-6420DB4 maintains 520 Mbps recording throughput even during RAID rebuilds, with 200 Mbps playback bandwidth for forensic review and incident investigation. The NVR supports flexible recording modes including continuous, event-triggered with pre/post recording, scheduled, and bookmark functions. Resolution flexibility spans from 32MP at 15 fps (H.265 only) and 12MP at 30 fps (H.265) down to D1 resolution at all 64 channels at 30 fps, accommodating diverse camera deployments within a single system.
Storage & Data Protection
With 16 SATA drive bays supporting up to 10TB per drive, the XRN-6420DB4 delivers 140TB of expandable storage for extended retention periods. RAID 5 and RAID 6 redundancy protect against drive failure, while automatic hot-swap capability enables seamless maintenance. Automatic Recovery Backup (ARB) with N+1 failover provides additional safeguarding, and the redundant power supply ensures continuous operation through power interruptions.
Network & Integration
Built-in ONVIF and SUNAPI protocol support enables integration with cameras from multiple manufacturers, reducing vendor lock-in and simplifying mixed-environment deployments. Multi-screen display with dynamic layout options supports efficient security operations center (SOC) configurations.

The XRN-6420DB4 is positioned for organizations requiring extreme scalability: 64 channels at up to 32MP resolution represents one of the highest native resolution capacities in the NVR market. The sustained 520 Mbps bandwidth during RAID rebuild is critical for production environments where recording interruptions are unacceptable. The dual HDMI configuration with mismatched refresh rates (30Hz for 4K, 60Hz for 1080p) suggests design intent for hybrid monitoring—high-resolution forensics on primary display, operational awareness on secondary.
For deployments considering this system, verify HDD sizing strategy: a fully populated 140TB array with H.265 compression and mixed 8-12MP camera loads will yield 20-30+ days retention depending on motion detection configuration. The Intel processor foundation ensures strong codec performance and future codec support through firmware updates.
