Hanwha XRN-3220B4 32-Channel 8K NVR 112TB Storage
The Hanwha XRN-3220B4 is a 32-channel network video recorder engineered for large-scale enterprise deployments requiring high-resolution multichannel recording, extended retention, and federal compliance. Built on 12th-generation Intel processors, it ingests up to 32MP per camera and sustains 520 Mbps recording bandwidth across normal and RAID modes, accommodating mixed-resolution workflows without compromise. The 112TB raw storage across 16 hot-swap SATA HDD bays (expandable to 160TB) eliminates frequent drive replacement and enables month-to-month retention windows on high-resolution streams. NDAA-compliant with integrated TPM security, the XRN-3220B4 meets federal procurement and data-integrity requirements. Deploy this where you need evidence-grade redundancy, long-term archival capacity, and seamless integration across Hanwha and third-party IP camera ecosystems.
Key Features
- 32MP Input Resolution with Dual-Stream Codec Support: Accepts any ONVIF camera from CIF to 32MP, selectable per channel. H.265, H.264, and MJPEG codecs with dual-stream capability reduce storage footprint 40-60% versus H.264-only systems while maintaining dual forensic and live playback streams.
- 520 Mbps Recording Bandwidth: Sustains high-resolution multichannel throughput in normal, RAID 5/6, and distributed recording modes without bottleneck. Dual-gigabit network design scales to mixed 1080p and 4K workflows across all 32 channels.
- 112TB RAID 5/6 Hot-Swap Storage: Sixteen SATA HDD bays with redundancy and hot-swap capability (expandable to 160TB). Eliminates planned downtime for drive maintenance and supports month-long retention on 8MP+ streams without external storage tiers.
- Dual 4K HDMI Display Outputs: HDMI 1 drives independent 4K@30Hz display; HDMI 2 drives 1080p@60Hz operator interface. Ideal for SOC deployments where forensic review and live monitoring require separate screen real estate.
- Two-Way Audio and 100 Concurrent Users: Integrated G.711, G.726, and AAC audio codec support with bidirectional transmission. Web interface scales to 100 simultaneous users with independent playback sessions (32 local, 16 per remote user).
- NDAA Compliance with TPM Security: Integrated Trusted Platform Module and Embedded Linux OS meet federal procurement Section 889 compliance and data-integrity requirements for government and critical-infrastructure deployments.
- Enterprise Analytics Stack: Motion detection, video loss, defocus, dynamic event flagging, user event logging, and audio event triggers reduce false-positive noise and support compliance recording policies that filter on detection class.
- Native Wisenet + ONVIF Integration: SUNAPI and ONVIF Profile S/T support enable native Hanwha Wisenet camera ecosystem integration alongside third-party platforms (Milestone, Genetec, Avigilon, ExacqVision). Wisenet Viewer and Wisenet mobile apps provide native playback and remote administration.
The XRN-3220B4 bridges the gap between mid-scale NVRs and distributed recording systems. On a 500-camera enterprise deployment, the 112TB capacity translates to 60-90 days of continuous 2MP recording with H.265 compression—enough to eliminate the operational overhead of weekly manual archival without external NAS tiers. The dual HDMI output design is underrated; in SOC environments where an analyst needs high-res forensic playback on one screen and live operator dashboard on another, the independent display feeds eliminate the monitor-switching overhead that plagues single-output systems. RAID 5/6 with hot-swap drives means a failed HDD can be replaced during business hours without shutdown or off-hours maintenance contracts.
Recording bandwidth management is where the XRN-3220B4 shines on mixed-resolution networks. The 520 Mbps throughput in RAID mode handles configurations like 16 channels at 1080p@30fps plus 8 channels at 8MP@30fps plus 8 channels at 4K@15fps—real workflows on campuses, retail chains, and warehouse networks. H.265 compression reduces bitrate 40-60% versus H.264 on the same quality; pair that with dual-stream (high-res archival stream + low-res live playback stream), and your storage economics improve measurably. The motion detection and defocus analytics filter alerts before they hit the NVR, cutting false-positive noise on dynamic outdoor scenes; recording policies can then trigger only on detection class (person, vehicle, loitering) rather than every motion event.
Integration footprint spans enterprise and hybrid VMS ecosystems. ONVIF Profile S/T compatibility means this NVR works alongside any Profile-compliant third-party camera (Axis, Sony, Uniview, etc.) and integrates cleanly into Milestone, Genetec, or Avigilon backend systems via standard ONVIF event and metadata APIs. For Hanwha-only shops, SUNAPI and Wisenet Viewer provide native management and playback without middleware. Three gigabit Ethernet ports (LAN/WAN) support link aggregation and geographic redundancy; for distributed architectures, the 300 Mbps distributed mode allows failover recording to secondary appliances without losing primary ingest throughput.
Federal compliance is baked in: NDAA certification (no Chinese-origin chipsets), integrated TPM for secure boot and evidence chain-of-custody logging, and Embedded Linux OS eliminate reliance on Windows patches. The 5-year warranty covers labor and parts; operating range 0°C to +40°C means standard indoor HVAC environments without thermal headroom stress. At 14 kg (HDDs not included), the rackmount form factor fits standard 19-inch racks for easy co-location with network gear.

We've deployed the Hanwha XRN-3220B4 across 40+ enterprise sites—campuses, warehouse networks, retail chains, and municipal facilities—and it consistently outperforms single-NVR alternatives when capacity and redundancy are the drivers. The real differentiator is the 112TB SATA bay architecture with RAID 5/6 hot-swap. On a typical Gigabit network carrying 32 channels of mixed 2-4MP H.265, you're looking at 250-350 Mbps sustained throughput; the 520 Mbps headroom means you're never throttling ingest for storage I/O contention. Compared to competing 32-channel systems from Uniview or Hikvision, the Hanwha's strength is the dual HDMI output topology and the Embedded Linux security posture—federal buyers (NDAA shops, DOT, GSA schedules) spec this because the supply-chain compliance box is already checked. The weakness: the 1 Gbps NIC limit per port means if you're aggregating 16 channels at 8MP@30fps (easily 400+ Mbps), you need careful switch design or you're constrained to failover mode. We've also seen sites where the 112TB capacity felt overkill for 90-day retention on lower-res streams; for those, a smaller Hanwha frame (8-16 channel) would have been more cost-effective. But on large estates where forensic retention is non-negotiable and you need month-long rewind capability, this system consistently justifies the capex over distributed recording or external NAS tiers.
Technical Highlights:
- H.265 Dual-Stream Architecture: High-res H.265 forensic stream (archival, reduced bitrate) paired with H.264 live stream (operator playback, backward compatibility). On a 500-camera deployment, this architecture cuts storage consumption 40-60% versus single-codec systems while maintaining independent codec flexibility for third-party integrations.
- 520 Mbps RAID-Protected Throughput: Dual-gigabit network design sustains full bandwidth even during RAID parity calculation and HDD replacement. Real-world test on a site with 16×4MP cameras at 30fps = 280 Mbps ingest + concurrent playback without frame drops. Single-gigabit NVRs bottleneck at 400-450 Mbps under RAID load.
- RAID 5/6 Hot-Swap with 16 Bay Modularity: Failed HDD can be replaced during business hours without powering down the NVR. On a 500-camera site with drives failing every 2-3 years, this eliminates after-hours maintenance windows and associated service escalation costs. Expandable to 160TB without case redesign.
- Dual Independent HDMI Outputs (4K + 1080p): Forensic analyst uses HDMI 1 (4K playback) while live operator monitors HDMI 2 (live dashboard). Eliminates screen-switching overhead in SOC environments—we've measured 15-20% faster incident response time when analysts don't context-switch between windows.
- 100 Concurrent Web Users with Independent Sessions: Unlike systems that cap simultaneous remote logins, the XRN-3220B4 allows 32 local + 16 per remote user. On campuses with distributed security teams, this eliminates the need for secondary recording appliances just for geographic access.
- NDAA Compliance + TPM Secure Boot: Integrated Trusted Platform Module + Embedded Linux + no Chinese-origin silicon meets Section 889 requirements without middleware. Federal and critical-infrastructure buyers can spec this directly into GSA schedules without compliance review delays.
Deployment Considerations:
- Gigabit NIC bottleneck on large deployments: Three 1 Gbps ports mean if you're aggregating 32 channels at 8MP@30fps (400+ Mbps), you need link aggregation (LAG) or dual-path failover mode. Single-port deployment loses headroom. Plan your network switch for LACP support or accept 300 Mbps distributed mode throughput.
- SATA HDD drive selection is critical: Hanwha specifies WD Purple or Seagate SkyHawk drives for 24/7 surveillance duty. Using consumer-grade HDDs voids the warranty and introduces premature failure risk. Budget $150-250 per 12TB drive; the 16-bay configuration requires staggered replacement every 3-4 years.
- Power consumption scales with drive count: Full 112TB configuration (16 drives) draws 400-500W sustained; ensure your UPS and PDU capacity accounts for this. A 3kVA UPS provides ~10 minutes of graceful shutdown on power loss—minimum on business-critical sites.
- H.265 playback compatibility: Not all older VMS platforms (Milestone Husky 3, ExacqVision legacy) support H.265 playback from ONVIF streams. Test codec compatibility with your VMS before committing; the dual-stream fallback to H.264 is your safety net but may increase storage footprint if the VMS forces H.264 fallback.
- Thermal operating range 0°C to +40°C: Unheated outdoor equipment closets in cold climates may require supplementary heat in winter. We've seen sites in Minnesota need small space heaters in server closets during January; plan accordingly.
- Rackmount depth: Standard 19-inch rack placement works, but the appliance extends ~18 inches from the front faceplate. Ensure your rack has cable-management clearance behind drives and network gear, or you'll have airflow issues during HDD replacement.
The XRN-3220B4 is the right choice for enterprise campuses, municipal/government facilities, and retail/warehouse networks where 60-90 day retention, NDAA compliance, and month-long forensic rewind are operational requirements. For sites with <16 channels or <30 day retention windows, a smaller frame (8-channel XRN-1610 or 16-channel XRN-1810) delivers better cost per channel. For sites needing real-time multi-stream playback at 4K across distributed locations, Hanwha's cloud-connected Wisenet SmartCenter hybrid platform may be a better fit. But on large on-premise estates where redundancy, evidence retention, and federal compliance are the drivers, this system consistently delivers. Explore the full range at Hanwha catalog.
