Hanwha XRN-6420DB4-20TB 64 Channel NVR

The Hanwha XRN-6420DB4-20TB is a 64-channel network video recorder designed to deliver enterprise-grade surveillance storage and processing for large-scale security deployments.

This NVR supports up to 20MP+ resolution input, enabling high-fidelity video capture across dozens of connected cameras. The system employs advanced H.265, H.264, and MJPEG compression codecs to optimize storage efficiency without compromising image quality. With 20TB of onboard storage, the recorder provides extended retention windows for forensic review and compliance documentation. Wide Dynamic Range (WDR) processing enhances visibility in mixed-lighting environments, critical for perimeter and entrance monitoring.

Built on an embedded Linux operating system, the XRN-6420DB4 delivers reliable, headless operation with minimal maintenance overhead. The unit measures 17.32" × 5.2" × 22.48" and features a black metal chassis designed for secure rack or cabinet installation in server rooms and control centers. Three gigabit Ethernet ports (RJ-45, 1Gbps each) support simultaneous LAN and WAN connectivity, enabling remote monitoring and centralized management across distributed locations.

Analytics capabilities include defocus detection, dynamic event triggering, and user-defined event rules, allowing operators to respond intelligently to motion, alarm conditions, and system anomalies. Audio support via G.711, G.726, and AAC (16/48 kHz) codecs enables two-way communication and incident audio logging. Full ONVIF compliance ensures seamless integration with third-party IP cameras, access control systems, and management platforms.

The recorder operates reliably across 0°C to +40°C ambient temperatures, suitable for indoor control room and climate-controlled facility deployment. Camera setup and storage configuration are managed through an intuitive web interface, reducing deployment time and technical overhead.
