Hanwha XRN-6420B2-20TB 8K 64-Channel NVR

The Hanwha XRN-6420B2-20TB is a professional-grade 64-channel network video recorder engineered for large-scale surveillance deployments requiring exceptional image fidelity and storage capacity.

This NVR delivers outstanding image quality across multiple codec standards. Supporting H.265, H.264, and MJPEG compression, the system optimizes bandwidth and storage efficiency without sacrificing detail. The recorder handles up to 32MP resolution input and 20MP+ streams, making it suitable for ultra-high-definition camera networks. WDR (Wide Dynamic Range) support ensures clear footage in challenging lighting conditions, while integrated analytics including defocus detection, dynamic events, and user event triggers enable intelligent monitoring across large venues.

Built for demanding enterprise environments, the XRN-6420B2-20TB features a robust metal chassis with compact 3.39-inch height, allowing dense rack-mount or cabinet installation. The device operates reliably across 0°C to +40°C, supporting both climate-controlled server rooms and semi-protected outdoor installations. With eight SATA HDD slots supporting up to 80TB total capacity, the recorder provides extended retention periods for forensic investigation and compliance requirements.

Connectivity is straightforward with three RJ-45 Gigabit Ethernet ports (1Gbps each) for LAN/WAN deployment, supporting both local and remote access architectures. The embedded Linux operating system runs reliably without external dependencies. Full ONVIF compliance ensures seamless integration with third-party IP cameras and management software, eliminating vendor lock-in concerns. Audio is supported via G.711, G.726, and AAC compression at 16/48kHz sampling rates for two-way communication and event logging.

The XRN-6420B2-20TB excels in tier-1 security deployments including critical infrastructure monitoring, large retail and hospitality networks, transportation hubs, and government facilities. Its 64-channel capacity, massive storage architecture, and standards-based design make it ideal for integrators building scalable, future-proof surveillance ecosystems.

The XRN-6420B2-20TB is purpose-built for operators managing large camera counts on mission-critical networks. The 80TB capacity is substantial, but calculate your actual retention based on codec selection—H.265 will extend recording windows significantly versus H.264. The three Gigabit ports work well for segmented networks; consider bonding or load-balancing if you're pushing close to line-rate throughput. ONVIF support is a major advantage for mixed-vendor environments. This recorder demands proper power conditioning and network infrastructure, so budget accordingly during deployment planning.
