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

The Hanwha XRN-6420B2-8TB is a 64-channel network video recorder engineered for large-scale surveillance deployments requiring ultra-high resolution and intelligent video management.

This NVR supports up to 32 MP resolution across multiple camera streams, delivering exceptional image clarity for detailed forensic review and real-time monitoring. The system employs advanced H.265 compression alongside H.264 and MJPEG codec support, optimizing bandwidth and storage efficiency without compromising image fidelity. With WDR (Wide Dynamic Range) capability, the recorder handles challenging lighting conditions—from backlighting to shadowed areas—ensuring consistent video quality across diverse environments. Integrated analytics including defocus detection, dynamic event triggers, and user event configuration enable intelligent alerting and automated workflow integration.

Built for durability and performance, the XRN-6420B2-8TB features a robust metal chassis with black finish, weighing 16.09 kg and dimensioned at 17.24" W × 3.39" H × 17.12" D for standard rack deployment. The recorder operates reliably across 0°C to +40°C ambient temperatures, suitable for both climate-controlled data centers and field installations. Eight SATA HDD slots accommodate up to 80 TB of internal storage, providing extended retention for high-resolution video archives.

Network connectivity is provided through three RJ-45 Gigabit Ethernet ports (1 Gbps each), supporting flexible LAN/WAN configurations for remote access and redundant network paths. The embedded Linux operating system ensures stability, security, and vendor-neutral device management. ONVIF compliance enables seamless integration with third-party IP cameras, VMS platforms, and monitoring software ecosystems. The recorder also incorporates audio processing with G.711, G.726, and AAC (16/48 kHz) compression, supporting two-way voice communication and audio event detection.

This system scales effectively across retail, transportation, critical infrastructure, and enterprise security applications where 64-channel consolidated recording, ultra-high resolution, and intelligent storage management are essential. The combination of advanced compression, multi-protocol support, and extensive storage capacity reduces operational complexity while maintaining investigative image quality.

The XRN-6420B2-8TB excels in high-channel-count deployments where you need consolidated recording without sacrificing resolution. The 8 TB base storage and H.265 codec efficiency mean you can retain weeks of 32 MP video in a compact form factor. The three independent Gigabit ports support network redundancy—critical for mission-critical sites. Verify your camera mix (megapixel range) and bandwidth capacity before deployment; 64 channels at peak resolution will require careful network design and potentially aggregated uplinks.
