Hanwha XRN-6420B2-16TB 8K 64-Channel NVR

The Hanwha XRN-6420B2-16TB is a high-capacity 64-channel network video recorder engineered for enterprise-scale surveillance deployments requiring advanced image fidelity and reliable long-term storage.

This 8K-capable NVR supports up to 32 MP resolution across simultaneous channels, delivering exceptional detail clarity for forensic review and real-time monitoring. The system employs H.265, H.264, and MJPEG compression codecs to optimize bandwidth and storage efficiency, critical for large-scale camera networks. Hardware-based WDR (Wide Dynamic Range) processing ensures balanced image quality in mixed lighting conditions, preserving detail in both highlights and shadows across diverse indoor and outdoor scenes.

Built on embedded Linux architecture with ONVIF compatibility, the XRN-6420B2-16TB integrates seamlessly into heterogeneous IP camera ecosystems. Three 1 Gbps Ethernet ports (RJ-45) support both LAN and WAN connectivity, enabling distributed monitoring, cloud backup, and multi-site management. The system runs integrated analytics including defocus detection, audio event monitoring, and dynamic/user-defined event triggers—reducing false alarms and focusing operator attention on genuine security events.

Storage capacity reaches 80 TB maximum across eight SATA HDD slots, providing weeks or months of rolling archive depending on resolution, frame rate, and codec selection. Audio compression via G.711, G.726, and AAC (16/48 kHz) enables two-way communication and incident audio logging. The compact 3.39-inch chassis (17.24" W × 17.12" D) fits standard 19-inch rack mounting or desktop deployment in control rooms.

Operating across 0°C to +40°C, the metal-chassis design handles both climate-controlled facilities and industrial environments. The 16 TB pre-installed storage configuration provides immediate deployment readiness while allowing future expansion for extended retention policies.

The XRN-6420B2-16TB excels in large-scale enterprise and government installations where 64-channel density and 32 MP detail are non-negotiable. The 80 TB maximum storage and H.265 efficiency make this platform cost-effective for long-term compliance recording. ONVIF support ensures vendor flexibility, and the dual-port network design supports failover and geographic redundancy. Plan for adequate cooling and UPS power—this is a data center-class appliance, not a small office recorder.
