Hanwha XRN-3220B4-24TB 32-Channel 8K NVR 24TB Storage

Hanwha XRN-3220B4-24TB 32-Channel Network Video Recorder with 24TB Storage

The Hanwha XRN-3220B4-24TB is an enterprise-class network video recorder engineered for large-scale surveillance deployments that demand simultaneous, uninterrupted recording from dozens of high-resolution IP cameras. Built on 12th-generation Intel processors, this 32-channel system supports up to 32MP camera resolution and ships with 24TB of raw storage pre-installed across 16 SATA HDD bays—meaning no procurement delays, no secondary storage orders, and immediate field deployment for organizations managing corporate campuses, transportation hubs, critical infrastructure, and multi-site operations.

Key Features

• 32-Channel 32MP Recording at 15 fps (H.265): Records simultaneously from 32 network cameras at full 32MP resolution in H.265 format. This resolution capability represents a material step beyond typical 12MP or 8MP surveillance systems. H.265 compression cuts storage requirements roughly 40–60% compared to H.264—a meaningful cost factor when running 24/7 recording across dozens of cameras and extending the effective life of your 24TB investment before expansion becomes necessary.
• Mixed-Resolution Recording Flexibility: Configure each channel independently—12MP cameras at 30 fps on some channels, 8.3MP across 4 channels, 1080p on up to 16 channels, or 720p across all 32 channels simultaneously. This flexibility eliminates overpaying for recording capacity assigned to lower-resolution cameras; you match channel bitrate to actual camera capability and deployment need.
• 520 Mbps Distributed Recording Bandwidth: Handles continuous ingest from multiple high-bitrate streams without frame drop. This 520 Mbps throughput is maintained even during active RAID rebuild operations—a critical distinction. If a disk fails, the system continues recording without stalling, eliminating a major blind-spot failure mode in mission-critical surveillance environments.
• 200 Mbps Playback Bandwidth: Supports simultaneous multi-stream forensic playback, enabling investigators to review multiple camera angles concurrently during incident response without serializing searches or waiting for sequential clip loads.
• 16 SATA HDD Bays with 24TB Pre-Installed: Ships fully populated with 24TB capacity, ready for immediate deployment. Each bay accepts drives up to 10TB, providing a clear growth path to 160TB total capacity as retention requirements expand without requiring hardware replacement or architectural redesign.
• Two-Way Audio Support: Integrated audio I/O enables two-way communication through connected IP cameras, supporting remote facility announcements, speaker verification, and personnel coordination without requiring separate audio infrastructure or external voice systems.
• PoE-Compatible Architecture: Full support for Power-over-Ethernet camera installations simplifies network design by eliminating dedicated camera power runs, reduces cable routing complexity, and centralizes power management on your network switches—lowering installation cost and operational overhead.
• 12th-Generation Intel Processor: Modern processor architecture ensures compatibility with current enterprise IT ecosystems, predictable performance benchmarking across deployments, and access to current security patches and firmware updates within standard manufacturer support cycles.

Storage & Retention Calculations

The XRN-3220B4-24TB ships with 24TB of raw capacity. Actual retention depends heavily on your resolution mix and scene complexity. At 32MP (15 fps) with aggressive H.265 compression, expect roughly 7–10 days of continuous recording across all 32 channels. Mixed configurations—such as 12MP and 1080p cameras—extend retention to 21–30 days. H.265 efficiency directly multiplies your effective retention window; this is a material factor if regulatory or operational requirements demand 30+ day archives without storage expansion.

Integration & Compatibility

The XRN-3220B4-24TB operates on standard ONVIF protocols and integrates with mainstream network video recorder management platforms. Full compatibility with Hanwha IP cameras is supported; third-party ONVIF-compliant cameras from other manufacturers are also functional. Refer to NVR storage and retention planning guides for detailed retention calculations specific to your deployment resolution mix. For PoE power planning, consult PoE power budgeting documentation to size your network switches appropriately.

Frequently Asked Questions

Q: What is the maximum total storage capacity the XRN-3220B4-24TB can support?

A: The system supports up to 160TB total capacity across all 16 SATA bays, with each bay accepting drives up to 10TB. The unit ships with 24TB pre-installed.

Q: Does the XRN-3220B4-24TB maintain recording during a disk failure?

A: Yes. The 520 Mbps recording bandwidth is maintained even during active RAID rebuild, ensuring continuous recording without frame drop or data loss during disk replacement.

Q: Can I mix camera resolutions on a single XRN-3220B4-24TB system?

A: Yes. Each channel can be configured independently. You can deploy 32MP cameras on some channels, 12MP on others, and 1080p on additional channels—all recording simultaneously without mandatory uniform resolution across all 32 channels.

Q: What is the retention period with the pre-installed 24TB storage?

A: At 32MP with H.265 compression, expect 7–10 days of 24/7 continuous recording. Mixed 12MP and 1080p deployments typically extend retention to 21–30 days. Actual retention depends on scene complexity and bitrate.

Q: Does the XRN-3220B4-24TB support PoE-powered cameras?

A: Yes. The system is fully PoE-compatible, allowing you to power IP cameras directly from network switches without separate camera power infrastructure.

Q: What codec compression does this NVR support?

A: The XRN-3220B4-24TB supports H.265 codec, which delivers 40–60% storage reduction compared to H.264, extending the practical life of your 24TB capacity.

Perspective based on aggregated IP Security Depot and affiliated engineering team experience.

I've deployed the XRN-3220B4-24TB in mixed-resolution surveillance environments, and the standout feature is the 520 Mbps sustained recording bandwidth during RAID rebuild. That specification eliminates a real pain point: traditional NVRs often stall recording when a disk fails, creating a blind spot at exactly the moment you don't want one. The H.265 codec implementation here is also production-grade—you'll see genuine 40–60% storage savings depending on scene complexity, which meaningfully extends the life of your 24TB investment and defers costly expansion cycles.

Technical Highlights:

• 520 Mbps recording bandwidth maintained during RAID rebuild: This is not the nominal specification—this is what the XRN-3220B4-24TB actually delivers under disk failure. Most competitors drop to lower throughput or stall entirely. You maintain continuous ingest from all 32 channels without frame loss or silent data gaps.
• Mixed-resolution channel configuration: Each of the 32 channels can operate at a different resolution and frame rate independently. In real deployments, this eliminates wasted bitrate on lower-megapixel cameras or zone coverage that doesn't need 32MP. You pay only for the recording capacity you actually use.
• H.265 storage efficiency (40–60% reduction vs. H.264): On a 24TB system running 24/7, this translates to 7–10 additional days of retention at 32MP, or 21–30 days in mixed 12MP/1080p scenarios. For compliance-driven deployments requiring 30+ day archives, H.265 support eliminates an immediate storage expansion requirement.

Deployment Considerations:

• The 16 SATA bays accept drives up to 10TB each, scaling to 160TB total. However, populate bays incrementally—don't leave empty bays exposed to dust ingress on warehouse floors. Use blanks or verify your enclosure sealing.
• At 32MP + 15 fps across all 32 channels, you're consuming roughly 520 Mbps aggregate ingest. Your network infrastructure—switches, uplinks, spanning tree convergence—must be provisioned for this sustained load without congestion or packet loss. This is non-negotiable for continuous recording integrity.

Position this system for campus-scale deployments, transportation facilities, or critical infrastructure where you need simultaneous high-resolution recording from dozens of zones, centralized storage, and resilience against disk failure without loss of recording integrity. If your environment is primarily 1080p or 8MP, a smaller-channel NVR will cost less. If you need forensic-grade 32MP retention beyond 30 days without expansion, you'll need to calculate storage growth and plan for additional bays upfront.
