Hanwha XRN-6420B2-40TB 8K NVR, 64-Channel

The Hanwha XRN-6420B2-40TB is a high-capacity 64-channel network video recorder engineered for enterprise-scale surveillance deployments requiring maximum storage and processing power in a compact form factor.

This NVR delivers exceptional image quality through support for 32MP resolution capture and 20MP+ processing capabilities, leveraging advanced H.265 compression alongside H.264 and MJPEG codecs to optimize bandwidth and storage efficiency. The inclusion of WDR (Wide Dynamic Range) technology ensures detail preservation in challenging lighting conditions, making it suitable for environments with mixed illumination levels. Built on embedded Linux architecture with full ONVIF compliance, the system integrates seamlessly with multi-vendor IP camera ecosystems, eliminating proprietary lock-in while maintaining operational flexibility.

Storage capacity reaches 40TB standard configuration with expandability to 80TB maximum via eight SATA HDD slots, accommodating extended recording periods and high-resolution footage retention. This makes the unit ideal for mission-critical applications where forensic review windows span weeks or months. Triple 1Gbps Ethernet ports (RJ-45) support simultaneous LAN/WAN connectivity, enabling distributed monitoring, cloud integration, and secure remote access architectures.

Analytics capabilities include dynamic event detection and user-defined event triggering, complemented by audio analytics with support for G.711, G.726, and AAC compression at 16/48kHz sampling rates. This multi-modal approach supports integrated security workflows combining video, audio, and metadata for comprehensive incident investigation.

The chassis measures 17.24" × 17.12" × 3.39" (W × D × H) and weighs 16.09 lbs, featuring a metal construction finished in black for professional installation in server rooms, security command centers, and network closets. Operating temperature range of 0°C to +40°C ensures reliable performance in controlled environments with standard HVAC systems.

Key capabilities include:

• 32MP resolution support with 20MP+ processing capacity
• 40TB pre-installed HDD, expandable to 80TB (8 SATA slots)
• Triple 1Gbps Ethernet for LAN/WAN deployment flexibility
• H.265/H.264/MJPEG codec support for bandwidth optimization
• WDR technology for high-contrast environment handling
• Full ONVIF compatibility for multi-vendor camera integration

The XRN-6420B2-40TB targets large-scale deployments where 64-channel capacity and substantial local storage are non-negotiable requirements. The 40TB standard configuration with 80TB expansion ceiling is particularly valuable for organizations avoiding frequent HDD replacement cycles or managing high-bitrate 4K+ camera streams. Triple Gigabit ports enable redundant network paths—a critical reliability feature often overlooked in mid-range NVRs. Verify your camera codec preference before purchase; while H.265 efficiency is excellent, legacy systems may require native H.264 support for seamless integration.
