Hanwha XRN-3220B4-48TB 32 CH NVR

The Hanwha XRN-3220B4-48TB is a 32-channel network video recorder engineered for mid-to-large scale surveillance deployments requiring robust storage capacity and reliable video management in embedded Linux environments.

This NVR delivers professional-grade video handling across 32 channels with support for up to 20MP+ camera streams. The system employs advanced H.265 compression alongside H.264 and MJPEG codecs, enabling efficient bandwidth utilization and storage optimization without sacrificing image clarity. Multi-codec support ensures compatibility with diverse camera ecosystems while dynamic WDR processing enhances detail recovery in high-contrast scenes. Audio integration via G.711, G.726, and AAC compression (16/48kHz) enables comprehensive surveillance workflows including two-way communication and incident verification.

Built for resilience and continuous operation, the XRN-3220B4-48TB features a compact metal chassis (17.32" W × 5.2" H × 22.48" D) designed for rack-mount or console deployment in control rooms and security operations centers. The embedded Linux platform provides system stability and minimizes maintenance overhead. Three 1Gbps RJ-45 Ethernet ports (LAN/WAN) enable reliable network connectivity and remote access across distributed monitoring environments. Operating temperature range of 0°C to 40°C (32°F to 104°F) supports both climate-controlled facilities and moderately varied environments.

The recorder integrates native ONVIF protocol support, ensuring seamless interoperability with third-party IP cameras, encoders, and management software. Built-in analytics encompassing defocus detection, dynamic event triggers, and user-defined events enable intelligent event logging and alert generation without external processing overhead. 48TB native storage provides extended recording windows for high-channel-count operations, reducing reliance on external archival systems.

Deployment scenarios range from retail and hospitality multi-location networks to transportation hubs, education campuses, and enterprise security operations requiring centralized video management. The 32-channel capacity combined with 20MP+ stream support addresses contemporary HD+ and 4K camera adoption without architectural redesign.

The XRN-3220B4-48TB suits integrators building large-scale systems where 32-channel density and native H.265 compression deliver measurable bandwidth savings. The 48TB capacity handles extended retention for multi-site operations, and ONVIF compliance eliminates vendor lock-in. Verify network infrastructure can handle aggregated bitrates before deployment—three 1Gbps ports work best with managed switching and QoS configuration.
