Hanwha XRN-6420B2-48TB 64-Channel 8K NVR

The Hanwha XRN-6420B2-48TB is a high-capacity 64-channel network video recorder designed for large-scale surveillance deployments requiring 8K resolution imaging and extensive storage capacity.

This NVR delivers exceptional image quality through support for 32 MP and 20 MP+ resolution streams, leveraging advanced H.265 compression alongside H.264 and MJPEG alternatives to optimize bandwidth and storage efficiency. The system's WDR (Wide Dynamic Range) capability ensures clear video in challenging lighting conditions, making it suitable for environments with mixed illumination levels. Multiple compression codec options provide flexibility in balancing image fidelity with network and storage demands across diverse camera installations.

Built on an embedded Linux operating system, the XRN-6420B2-48TB integrates ONVIF compliance for seamless interoperability with third-party IP cameras and systems. The recorder supports sophisticated analytics including defocus detection, audio analysis, and dynamic event triggering, enabling proactive monitoring and intelligent alarm management. Audio compression via G.711, G.726, and AAC (16/48 kHz) codecs supports two-way communication and forensic audio review when integrated with audio-capable cameras.

Storage capacity reaches 80 TB maximum across eight SATA HDD slots, accommodating extended retention periods for high-resolution multi-channel recording. The pre-configured 48 TB model balances capacity with operational efficiency for organizations requiring substantial archival capability. Network connectivity via three 1 Gbps RJ-45 ports (supporting LAN/WAN configurations) enables distributed monitoring, remote administration, and multi-site management scenarios.

The metal chassis construction and compact 3.39-inch height facilitate flexible rack-mount or shelf deployment in server rooms, control centers, and security operations facilities. Operating temperature range of 0°C to +40°C supports standard indoor environments. User event configuration allows custom rule creation for site-specific monitoring requirements, enhancing operational control.

The XRN-6420B2-48TB addresses large enterprise and critical infrastructure surveillance needs where channel density and storage capacity are primary requirements. The 48 TB configuration provides meaningful retention at high resolution without requiring immediate expansion, though the modular 80 TB maximum allows growth as archive requirements evolve. ONVIF compliance simplifies multi-vendor camera deployments, and the trio of Gigabit ports supports both centralized recording and distributed WAN scenarios common in campus or multi-location operations. This is a purpose-built recorder for organizations where recording capacity and channel count outweigh compact form factor priorities.
