Hanwha XRN-3220B4-20TB 32 Channel NVR

The Hanwha XRN-3220B4-20TB is a 32-channel network video recorder engineered for enterprise-scale surveillance deployments requiring high-capacity storage and reliable multi-stream management.

Image Quality and Recording Capabilities
This NVR supports up to 20MP resolution streams, accommodating modern high-definition and megapixel camera networks. It processes multiple compression standards—H.265, H.264, and MJPEG—optimizing bandwidth and storage efficiency across varied camera types. The device handles dynamic event recording and defocus analytics, enabling intelligent capture of motion-triggered or anomaly-based events without continuous full-resolution logging.

Build and Physical Design
Constructed with a metal chassis and finished in black, the XRN-3220B4-20TB measures 17.32" (W) × 5.2" (H) × 22.48" (D), fitting standard rack or shelf mounting in server environments. Its compact depth allows integration into tight installation spaces while maintaining professional aesthetics. The embedded Linux operating system ensures stable, headless operation with minimal maintenance overhead.

Storage and Connectivity
Provisioned with 20TB of internal storage, the unit handles extended retention periods for 32-camera arrays. Three RJ-45 Gigabit Ethernet ports (LAN/WAN, 1Gbps) enable redundant network paths and remote management. ONVIF protocol compliance guarantees interoperability with third-party IP cameras and management software, reducing vendor lock-in risk and simplifying system expansion.

Audio and Analytics Integration
Integrated audio support includes G.711, G.726, and AAC (16/48kHz) compression, enabling two-way communication and incident documentation. Built-in analytics detect defocus conditions, dynamic events, and user-defined triggers, reducing false positives and focusing storage on actionable footage. Camera setup wizards streamline configuration for large deployments.

Deployment Range
Rated for 0°C to +40°C operation, the XRN-3220B4-20TB suits climate-controlled server rooms, equipment closets, and small-to-medium facility deployments. Ideal for retail chains, office complexes, light industrial facilities, and institutions managing 20+ camera sites.

Key Features:

• 32-channel capacity with 20MP stream support
• 20TB onboard storage for extended retention
• H.265/H.264/MJPEG codec flexibility
• Gigabit redundant networking (3× RJ-45 ports)
• ONVIF-compliant for open ecosystem integration
• Embedded Linux OS with defocus and dynamic event analytics

The XRN-3220B4-20TB is a solid choice for facility managers stepping up from smaller NVR deployments. The 32-channel density and 20TB capacity provide meaningful runway for 18–24 month retention on moderate-traffic sites. ONVIF support is critical—it prevents costly camera replacement if you need to pivot vendors. Budget for proper network segmentation and consider a second Gigabit port for failover; three ports is minimum for enterprise reliability, and that 0–40°C operating window means datacenter placement, not outdoor installations.
