Hanwha XRN-3220B4-56TB 32 Channel NVR

The Hanwha XRN-3220B4-56TB is a 32-channel network video recorder engineered for medium to large-scale surveillance deployments requiring high-capacity storage and advanced video analytics in a compact form factor.

This NVR supports up to 32MP resolution per channel and delivers exceptional image quality through H.265, H.264, and MJPEG compression formats. The H.265 codec significantly reduces bandwidth and storage requirements without compromising clarity, making it ideal for facilities managing multiple high-resolution streams simultaneously. Wide Dynamic Range (WDR) processing ensures optimal image quality in challenging lighting conditions, from bright sunlight to dimly lit areas, providing forensically valuable video across diverse environments.

Built with an embedded Linux operating system, the XRN-3220B4-56TB offers a stable, purpose-built platform optimized for continuous recording and playback. Its metal chassis and robust construction are designed for reliable operation across standard indoor environments, with an operating temperature range of 0°C to +40°C (32°F to 104°F). The unit measures 17.32" × 5.2" × 22.48", fitting efficiently into standard server racks or equipment cabinets without consuming excessive floor space.

Connectivity is handled through three RJ-45 Gigabit Ethernet ports (1Gbps each) supporting both LAN and WAN configurations, enabling flexible network topology and remote access. ONVIF protocol compliance ensures seamless integration with cameras and third-party management software from multiple manufacturers, eliminating vendor lock-in concerns. The recorder supports advanced audio codecs including G.711, G.726, and AAC (16/48kHz), enabling two-way audio and synchronized audio-video recording for comprehensive incident documentation.

Integrated analytics include defocus detection, dynamic event processing, and user-defined event triggers, automating threat detection and reducing reliance on 24/7 manual monitoring. The 56TB storage capacity provides extended retention for medium-resolution streams or shorter retention for maximum-resolution feeds, depending on frame rate and compression settings. Storage configuration supports flexible drive arrays for redundancy and capacity scaling.

Key Features:

• 32-channel support with up to 32MP resolution per camera
• 56TB internal storage with efficient H.265 compression
• Embedded Linux OS with WDR and advanced video analytics
• Three Gigabit Ethernet ports for LAN/WAN deployment
• ONVIF-compliant for cross-manufacturer interoperability
• G.711, G.726, and AAC audio codec support

The XRN-3220B4-56TB is a solid workhorse for integrators managing large multi-camera systems where storage efficiency and cross-platform compatibility matter. The H.265 codec and 56TB capacity give you meaningful retention without oversizing infrastructure, and the three Gigabit ports handle redundancy and remote monitoring effectively. Confirm your camera mix supports ONVIF before deployment to maximize the recorder's flexibility, and plan storage based on actual frame rates—32MP streams consume capacity quickly at 30fps.
