Hanwha XRN-6420B2 64CH 8K NVR

The Hanwha XRN-6420B2 is a 64-channel 8K network video recorder engineered for large-scale surveillance deployments requiring exceptional image fidelity and reliable long-term storage.

Built on a 32MP capable platform with support for up to 20MP+ resolution streams, this NVR accommodates the latest high-definition camera technologies while maintaining backward compatibility through H.265, H.264, and MJPEG codec support. The H.265 compression standard ensures efficient bandwidth utilization and reduced storage overhead—critical for operations managing dozens of simultaneous camera feeds. WDR (Wide Dynamic Range) processing enhances image quality in challenging lighting conditions, enabling clearer forensic review and real-time monitoring across varying environments.

The XRN-6420B2 features eight SATA HDD slots with a maximum capacity of 80TB, delivering substantial local storage for extended retention periods without reliance on external systems. The embedded Linux operating system provides stability and security while reducing operational complexity. Three 1Gbps Ethernet ports facilitate redundant network configurations and load balancing across LAN/WAN infrastructure, essential for geographically distributed or mission-critical installations.

Onboard analytics capabilities—including defocus detection, dynamic event processing, and user-defined event triggers—enable intelligent alerting and automated responses to suspicious activity. G.711, G.726, and AAC audio compression support integrated two-way communication and environmental monitoring when paired with compatible microphone-equipped cameras. Full ONVIF compliance ensures seamless integration with third-party IP cameras and management platforms, protecting system flexibility and future hardware investments.

The unit operates reliably in temperatures from 0°C to +40°C (32°F to 104°F), suitable for controlled indoor environments including data centers, command centers, and secure facilities. Housed in a durable black metal chassis measuring 17.24″ × 3.39″ × 17.12″ and weighing 16.09 lbs, the compact 1U form factor fits standard rack installations.

The XRN-6420B2 is purpose-built for organizations requiring serious storage density and multi-camera management without overprovisioning. The 64-channel architecture paired with H.265 compression and up to 80TB local storage creates an economical backbone for enterprise surveillance. ONVIF support is non-negotiable for long-term deployment flexibility. Confirm your network infrastructure can handle consistent 1Gbps throughput across all three ports if leveraging redundancy—this unit will saturate bandwidth on under-provisioned gigabit networks.
