Hanwha XRN-3220B4-12TB 32-Channel 8K NVR
The Hanwha XRN-3220B4-12TB is a powerful 32-channel Intel-based network video recorder engineered for enterprise and large-scale IP surveillance deployments. Supporting up to 32MP camera resolution and 8K capability, this NVR delivers the performance and storage capacity required for demanding multi-camera surveillance environments. Pre-configured with 12TB of raw storage and expandable to 160TB across 16 SATA HDD bays, the XRN-3220B4 provides flexible scalability for growing security needs.
Key Features
- 32-channel simultaneous recording at up to 520 Mbps (distributed mode) or 300 Mbps (normal mode)
- Support for up to 32MP camera resolution with H.265, H.264, and MJPEG codec flexibility
- Dual-stream recording capability for concurrent high-quality and bandwidth-optimized streams
- 16 SATA HDD bays with hot-swap capability and support for drives up to 10TB each
- RAID 5 and RAID 6 support with automatic degradation and full-bandwidth rebuild
- Two-way audio support for interactive surveillance communication
- PoE compatibility for streamlined camera integration
- WiseStream intelligent bandwidth optimization on compatible Wisenet cameras
Recording & Playback Performance
The XRN-3220B4 accommodates diverse surveillance scenarios through multiple recording modes: 32MP at 15 fps (H.265), 12MP at 30 fps, 8.3MP (4-channel at 30 fps), 1080p (16-channel at 30 fps), and 720p (32-channel at 30 fps). Multi-stream playback reaches 200 Mbps bandwidth, enabling simultaneous review and live monitoring. H.265 compression delivers superior quality at lower bandwidth compared to H.264, while MJPEG support ensures broad camera interoperability.
Storage & Redundancy
With 16 hot-swappable SATA bays and support for drives up to 10TB each, the XRN-3220B4 scales from the included 12TB base configuration to 160TB maximum capacity. RAID 5 and RAID 6 configurations protect against drive failure while maintaining full 520 Mbps rebuild bandwidth. Automatic Recovery Backup (ARB) with N+1 failover ensures business continuity in mission-critical deployments. iSCSI support enables network-attached storage expansion for additional flexibility.
Applications
Ideal for large campuses, transportation hubs, retail chains, government facilities, and critical infrastructure where high-resolution, multi-camera surveillance is essential. The dual-stream capability and WiseStream optimization reduce storage requirements without compromising image quality, making it cost-effective for bandwidth-constrained environments.

The XRN-3220B4 stands out for its Intel-based architecture, delivering reliable performance in enterprise settings. The 520 Mbps bandwidth in distributed mode accommodates demanding 32-channel 32MP deployments with headroom for redundancy and failover processes. RAID 6 support and ARB functionality address mission-critical requirements where data loss is unacceptable.
The dual-stream architecture intelligently balances storage efficiency with quality retention—particularly valuable when paired with WiseStream-compatible Wisenet cameras. For organizations requiring scalable, redundancy-rich surveillance infrastructure with future-proof 8K support, this NVR represents a mature, production-grade solution.
