Hanwha XRN-6420B2-80TB 8K 64-Channel NVR

The Hanwha XRN-6420B2-80TB is a high-capacity 64-channel network video recorder engineered for large-scale surveillance deployments requiring massive storage and advanced video processing capabilities.

This NVR supports up to 32 MP resolution input and 20 MP+ recording, delivering exceptional image clarity across dozens of simultaneous camera feeds. The recorder leverages H.265, H.264, and MJPEG compression standards to optimize storage efficiency without sacrificing fidelity. Wide Dynamic Range (WDR) processing enhances performance in mixed lighting conditions, while integrated analytics—including Defocus, Audio, Dynamic Event, and User Event detection—enable intelligent monitoring and automated alerting across the surveillance network.

Built on an embedded Linux operating system, the XRN-6420B2-80TB provides a stable, purpose-built platform for continuous operation. The unit accommodates up to eight SATA HDD slots with maximum 80 TB total storage capacity, ensuring extended retention periods for high-resolution multi-channel recording. Its metal chassis and compact 3U form factor (17.24" W × 3.39" H × 17.12" D) integrate cleanly into standard server racks, while the 16.09 lb weight allows flexible mounting in control centers or distributed recording locations.

Connectivity includes three 1 Gbps RJ-45 Ethernet ports (LAN/WAN configuration), enabling redundant network paths and remote management across enterprise infrastructure. Full ONVIF compliance ensures interoperability with third-party IP cameras and video management software, eliminating vendor lock-in and supporting mixed-brand camera ecosystems. Audio compression via G.711, G.726, and AAC (16/48 kHz) provides synchronized sound recording and two-way communication capabilities.

The device operates reliably across 0°C to +40°C ambient temperatures, making it suitable for both climate-controlled server rooms and ruggedized field deployments. Its scalable architecture supports growth from small multi-camera sites to enterprise installations with 64+ simultaneous streams.

The XRN-6420B2-80TB is built for facilities that need to ingest and retain massive volumes of high-resolution video. The 80 TB capacity combined with H.265 compression gives you months of retention on a 64-camera array, while ONVIF support and multiple Ethernet ports simplify integration into existing security infrastructure. If you're scaling a multi-site deployment or upgrading from smaller NVRs, this unit's embedded Linux foundation and rack-mount design make it a practical long-term investment.
