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

The Hanwha XRN-6420B2-64TB is a high-capacity 64-channel network video recorder engineered for large-scale surveillance deployments requiring advanced analytics, massive storage, and seamless IP camera integration.

This 8K-capable NVR delivers exceptional image quality and processing power across its 64 channels, supporting up to 32 MP resolution streams. The system employs H.265, H.264, and MJPEG compression codecs, allowing flexible bandwidth and storage optimization across mixed camera ecosystems. H.265 compression reduces storage demands by up to 50% compared to H.264, extending the operational life of your archival infrastructure without sacrificing frame rate or detail.

The XRN-6420B2-64TB features eight SATA HDD slots with a maximum capacity of 80 TB, enabling extended retention periods critical for corporate security, retail operations, and institutional surveillance. The embedded Linux operating system provides a stable, purpose-built foundation with native ONVIF compliance, ensuring compatibility with third-party IP cameras and management platforms. Audio support via G.711, G.726, and AAC compression enables two-way communication and synchronized audio-visual recording for forensic investigations and live incident response.

Built-in analytics capabilities including defocus detection, dynamic event triggers, and user-defined event rules allow for intelligent monitoring without external servers. The system supports camera setup workflows that simplify multi-camera provisioning across enterprise networks. Three Gigabit Ethernet ports (RJ-45, 1 Gbps each) deliver robust connectivity for LAN/WAN configurations, supporting remote access, cloud integration, and distributed recording architectures.

The recorder operates across 0°C to +40°C environmental conditions, accommodating server rooms, secure facilities, and temperature-controlled indoor installations. Its compact 3.39" height (17.24" × 17.12" footprint, 16.09 lbs) fits standard 19" racks and equipment cabinets. The all-metal black chassis ensures durability and professional appearance in control centers and server environments.

The XRN-6420B2-64TB is purpose-built for facilities managing 40–64 megapixel-capable camera fleets where storage density and codec flexibility matter. The 80 TB ceiling and H.265 support make this recorder ideal for long-term forensic retention in high-traffic environments—retail chains, airports, and government campuses benefit most. Verify your network architecture supports Gigabit throughput across all 64 channels before deployment; this unit demands sufficient WAN bandwidth if cloud failover is required.
