Hanwha XRN-3220B2-20TB 32-Channel 8K NVR with 20TB Storage
Overview
The Hanwha XRN-3220B2-20TB is a 32-channel network video recorder purpose-built for enterprise and large-scale surveillance deployments. Running on Intel 12th-generation processor architecture, this NVR ships with 20TB of onboard storage and delivers the distributed bandwidth and processing power to simultaneously record all 32 channels at 32MP resolution without frame-rate compromise. The combination of high-channel density, multi-codec support, and expandable storage makes it suitable for multi-facility operations, transportation hubs, large retail complexes, critical infrastructure, and government surveillance networks where forensic-quality retention and extended playback are non-negotiable. This is the recorder that handles the load when you cannot afford dropped frames or resolution scaling to fit bandwidth limits.
Key Features
- 32-channel simultaneous recording at up to 32MP resolution: Captures forensic-grade detail across all channels at native resolution without rate reduction. Critical for identification, investigation, and compliance audits in large deployments where you cannot sacrifice clarity to fit a smaller bitstream.
- 520 Mbps distributed recording bandwidth; 300 Mbps normal mode: The 520 Mbps ceiling ensures simultaneous high-bitrate feeds from all 32 channels remain lossless. Normal mode (300 Mbps) provides operational flexibility when mixing camera resolutions or lower-bitrate surveillance tiers, keeping the recorder responsive under varied load.
- H.265, H.264, and MJPEG codec support: H.265 cuts storage overhead roughly 40–60% compared to H.264, directly extending retention on the same hardware. For 24/7 multi-camera recording, this translates to weeks or months of additional archive without purchasing additional drives.
- 20TB pre-installed storage, expandable to 80TB across 8 SATA HDD bays: Modular expansion means you scale capacity without forking for a new recorder. Add drives as retention policies tighten or coverage expands—predictable cost growth tied to operational need, not forced hardware replacement.
- Dual HDMI outputs—4K UHD (HDMI1) and 1080p@60Hz (HDMI2): Independent resolution outputs let you run a wall-mounted 4K overview display and a lower-latency operator workstation monitor simultaneously without video switching, scaling artifacts, or display matrix gear. Real-world control-room efficiency.
- Up to 64-division simultaneous multi-channel display with dynamic layout switching: View all 32 channels at once, group by zone or facility, or prioritize critical areas on the fly. Essential in high-throughput control rooms where monitoring teams juggle dozens of simultaneous feeds.
- Dual-stream recording: Record one stream at high quality for forensic review and a second at lower bitrate for efficient long-term archive. Preserves investigative detail on demand while reducing storage strain on day-to-day operations.
- Two-way audio support: Enables interactive communication from the NVR to remote sites or field personnel, speeding incident response and real-time operational coordination without separate intercom systems.
- PoE camera compatibility: Integrate PoE-powered cameras without separate power distribution infrastructure. Reduces cable runs, conditioning hardware, and on-site wiring complexity.
- 200 Mbps playback bandwidth: Supports concurrent forensic review and backup operations without stalling live recording. When security teams, auditors, and administrators access archives simultaneously, the recorder does not drop incoming feeds.
Integration & Compatibility
The XRN-3220B2-20TB is ONVIF-compliant, integrating with standard VMS platforms and management software from major vendors. The 12th-generation Intel processor ensures broad codec and third-party analytics plugin support. Dual HDMI output architecture handles mixed-resolution camera deployments without external upscalers or video matrix switches. Two-way audio and PoE camera integration simplify provisioning in facilities migrating from analog or hybrid infrastructure to IP-native systems. NVR selection and sizing guides help confirm this channel and bandwidth class matches your specific footprint and retention model.
When to Choose a Different Model
If your deployment requires fewer than 16 simultaneous channels at forensic resolution, or if you are targeting sub-32MP feeds at modest bitrates, a lower-channel-density recorder in the Hanwha family may deliver better cost efficiency without sacrificing codec flexibility or expansion headroom. Conversely, if you need more than 80TB raw capacity or require specialized analytics accelerators (such as object detection or people counting at the appliance level), evaluate higher-tier or purpose-built intelligence-focused NVRs. For deployments mixing PoE and non-PoE cameras, confirm that your network infrastructure can deliver the aggregated bandwidth the XRN-3220B2-20TB will draw without saturation or packet loss.
Frequently Asked Questions
Q: What is the maximum resolution the XRN-3220B2-20TB can record on all 32 channels simultaneously?
A: Up to 32MP at native resolution across all 32 channels, assuming sufficient bandwidth and storage allocation. The 520 Mbps distributed mode provides the bandwidth headroom; lower resolutions (e.g., 12MP or 8MP per channel) reduce bitrate and extend retention proportionally.
Q: How much does H.265 compression reduce storage requirements compared to H.264?
A: H.265 typically cuts storage overhead 40–60% depending on scene complexity and motion. On a 24/7 multi-camera recorder, this savings compounds quickly—potentially adding weeks or months of archive retention on the same hardware without additional drives.
Q: Can I mix different camera resolutions on the same recorder?
A: Yes. The XRN-3220B2-20TB supports simultaneous recording of multiple resolutions, codecs, and frame rates on different channels. Dual-stream recording also allows you to capture high-quality detail on priority channels while archiving lower-bitrate secondary streams, optimizing storage efficiency.
Q: What is the maximum storage capacity of the XRN-3220B2-20TB?
A: 80TB across 8 internal SATA HDD bays. The unit ships with 20TB pre-installed; additional drives can be added incrementally as retention policies tighten or coverage grows, without replacing the entire system.
Q: Does the XRN-3220B2-20TB support two-way audio communication?
A: Yes. Two-way audio is supported, enabling real-time interaction from the NVR to remote camera locations or field sites. Useful for incident response coordination without requiring separate intercom or paging infrastructure.
Q: What VMS platforms are compatible with the XRN-3220B2-20TB?
A: As an ONVIF-compliant device, the XRN-3220B2-20TB integrates with any standards-based VMS or network camera management platform. Confirm specific version compatibility with your VMS vendor before deployment.

The XRN-3220B2-20TB is purpose-built for deployments where you cannot afford frame drops, resolution scaling, or storage surprises. Its 520 Mbps distributed bandwidth and 12th-gen Intel core ensure that all 32 channels record simultaneously at forensic resolution without bottlenecks—something smaller recorders struggle with under real-world mixed-load conditions. The modular storage architecture (expandable from 20TB to 80TB) is particularly valuable in large facilities where retention policies tighten over time or coverage grows incrementally; you scale capacity without forking for new hardware.
Technical Highlights:
- 520 Mbps distributed bandwidth with dual HDMI (4K + 1080p): Supports simultaneous high-bitrate recording on all 32 channels and independent 4K wall display + operator workstation monitoring without video switching, display scaling, or matrix equipment overhead.
- H.265 + H.264 + MJPEG codec flexibility: H.265 cuts archive storage by 40–60% versus H.264 on 24/7 multi-camera systems, directly extending retention or reducing drive requirements. Mixed-codec support handles legacy and modern camera integrations on the same recorder.
- 8 SATA HDD bays, 20TB pre-installed, expandable to 80TB: Modular architecture means you add capacity incrementally tied to operational need—no forced system replacement as your retention policy or footprint grows.
- 200 Mbps playback bandwidth: Forensic teams and auditors can review archived footage concurrently without stalling live recording, essential in high-throughput control rooms or compliance-heavy environments.
Deployment Considerations:
- The 520 Mbps distributed mode is ceiling performance; normal mode (300 Mbps) is sufficient for most mixed-resolution deployments but leaves less headroom for bitrate spikes. Confirm your camera mix fits your target bandwidth budget before committing.
- Eight internal SATA bays require careful HDD selection and sparing strategy. Drives fail; plan for hot-swap spares and monitor SMART health actively, especially in 24/7 mission-critical installations.
- HDMI1 (4K) and HDMI2 (1080p) are independent streams, not downscaled duplicates—plan your display topology carefully to avoid redundant wiring or signal loss.
The XRN-3220B2-20TB is the right call for large facilities, transportation hubs, or retail campuses running 20+ simultaneous camera feeds at high resolution and requiring extended forensic retention. It is not a bargain-basement recorder—it is a load-bearing appliance for deployments where dropped frames or storage surprises are unacceptable.
