Hanwha XRN-3220B4-40TB 32 Channel NVR

The Hanwha XRN-3220B4-40TB is a 32-channel network video recorder engineered for enterprise-scale surveillance deployments requiring high-resolution image capture, reliable storage, and seamless IP camera integration.

This NVR supports up to 32MP resolution and 20MP+ streams, delivering exceptional image clarity across multi-camera installations. The recorder is equipped with advanced compression standards—H.265, H.264, and MJPEG—enabling efficient bandwidth and storage utilization without sacrificing visual fidelity. Wide Dynamic Range (WDR) processing enhances performance in challenging lighting conditions, while built-in analytics including defocus detection, audio detection, dynamic events, and user-defined events provide intelligent monitoring and incident response capabilities.

Built for professional installations, the XRN-3220B4-40TB features a rugged metal chassis with compact form factor (17.32" W × 5.2" H × 22.48" D), allowing flexible rack or shelf mounting in control rooms and security operations centers. The embedded Linux operating system provides stability and reduced maintenance overhead, while the 40TB storage capacity supports extended retention for large-scale operations. Operating temperature range of 0°C to +40°C (32°F to 104°F) ensures reliable performance across standard indoor environments.

Network connectivity is provided via three RJ-45 Gigabit Ethernet ports (1Gbps each) for LAN/WAN deployment, enabling remote access and multi-site management. ONVIF compliance ensures interoperability with third-party IP cameras and management platforms, eliminating vendor lock-in and supporting heterogeneous camera ecosystems. Audio support via G.711, G.726, and AAC compression (16/48 kHz) enables two-way communication and audio-based event triggering.

The recorder's extensive feature set makes it suitable for corporate facilities, retail chains, transportation hubs, and critical infrastructure environments where simultaneous monitoring of dozens of camera feeds and extended archival are required.

The XRN-3220B4-40TB is a solid midrange choice for operators deploying 20-32 IP cameras across a single or distributed site. The combination of 40TB storage, triple Gigabit uplinks, and ONVIF support gives you flexibility in camera selection and network architecture. H.265 codec support is a practical advantage for managing bandwidth in bandwidth-constrained environments. Verify your camera resolution and frame rate requirements upfront—this recorder's analytics engine is event-driven, so pair it with quality camera firmware for best results.
