Hanwha WRR-P-S204S-112TB 2U Rackmount Network Video Recorder
The Hanwha WRR-P-S204S-112TB is a 2U rackmount NVR engineered for enterprise surveillance deployments where storage density, sustained recording throughput, and data center integration are foundational requirements. With 112TB raw storage capacity (87TB usable under RAID 5), this recorder handles mid-to-large scale camera networks without the storage bottlenecks that constrain undersized systems. It ships with Wisenet WAVE video management software pre-installed and four Professional licenses included—eliminating the typical separate VMS licensing cost and reducing deployment overhead on large projects by weeks.
Key Features
- 12 Hot-Swappable 3.5" HDD Bays: Front-facing drive slots allow you to add, replace, or upgrade storage without powering down or removing the recorder from the rack. On 24/7 operations where maintenance windows are expensive or unavailable, this matters significantly. No drive failure forces an extended outage.
- 112TB Raw Storage (87TB Usable): Twelve 3.5" drive slots support the industry's standard high-capacity configuration. At 87TB usable with RAID 5, this translates to months of uninterrupted 24/7 recording from dozens of concurrent camera streams—a real advantage if your deployment requires 90+ days of retention or operates multiple sites from a single data center NVR.
- 470 Mbps Sustained Recording Bandwidth: This throughput ceiling accommodates roughly 40–60 concurrent 4K (5MP) streams or 100+ 1080p streams without frame drops during peak traffic. For large retail, campus, or industrial deployments, this headroom prevents the tradeoff between live analytics processing and reliable recorded playback that undersized recorders force.
- H.265 Video Compression: Reduces bandwidth and storage requirements 40–60% compared to H.264, depending on scene complexity. On a 470 Mbps recorder with 87TB usable storage, this compression efficiency directly extends retention windows or accommodates more concurrent camera streams without sacrificing image quality.
- Flexible RAID Architecture (RAID 0, 1, 5, 6): RAID 5 and 6 configurations protect against single or dual drive failure—the industry standard for mission-critical surveillance. RAID 0 maximizes capacity if your backup strategy is managed separately. The choice stays with your deployment, not the recorder's limitations.
- 8GB NV (Non-Volatile) Cache: Provides write buffering during peak recording and playback spikes. Prevents frame loss when multiple high-bitrate streams arrive simultaneously—essential on systems operating near the 470 Mbps bandwidth ceiling.
- Wisenet WAVE Professional Pre-Installed & Licensed: Four Professional licenses ship ready to deploy. No additional software purchase, no license key hunting, no separate VMS server infrastructure to maintain. For integrators managing dozens of sites, this pre-configuration reduces per-project onboarding time and ongoing support overhead.
- Standard 19" Rackmount Form Factor: Fits any data center or server room with included sliding rail kit. Dimensions (18.97" W × 3.41" H × 30.39" D) integrate seamlessly into existing infrastructure without custom mounting or bracket engineering.
Integration & Compatibility
The WRR-P-S204S-112TB integrates with any standards-compliant IP camera supporting RTSP or ONVIF—by design, NVR systems remain equipment-agnostic. Wisenet WAVE Professional provides native optimization for Hanwha Wisenet IP cameras (superior codec efficiency and analytics integration), but does not require them. If your deployment mixes vendors—Axis, Hikvision, Uniview, or others—the recorder's RTSP/ONVIF ingestion still operates normally. You simply forego some vendor-specific optimizations like deep codec integration or proprietary metadata handling.
For large multi-site deployments, review your storage and retention requirements to confirm 87TB usable capacity meets your timeline. At 470 Mbps sustained throughput, confirm your network infrastructure (switch uplinks, network segmentation) can reliably deliver that bandwidth during peak recording periods without congestion-induced frame loss.

Frequently Asked Questions
Q: What's the difference between 112TB raw and 87TB usable?
A: Raw capacity is the sum of all twelve 3.5" drives (typically 112TB). Usable capacity accounts for RAID 5 overhead—one drive's worth of space is reserved for parity (fault tolerance). RAID 5 requires roughly 1/n of total capacity for parity; with 12 drives, that's approximately one full drive (87TB usable from 112TB raw). RAID 6 offers dual-drive protection but reserves two drives' worth of capacity, reducing usable space further.
Q: Can I install the WRR-P-S204S-112TB in an existing server rack without special power or cooling?
A: The unit is 2U and designed for standard 19" racks. Power requirements and thermal output depend on the specific model's specs (not included in this brief). Verify your rack's available power capacity, UPS support, and ventilation before installation. Contact the manufacturer or consult the full technical datasheet for exact power draw and thermal specifications.
Q: Does the WRR-P-S204S-112TB support cameras from multiple manufacturers?
A: Yes. The recorder accepts any IP camera supporting RTSP or ONVIF protocol—this includes Axis, Hikvision, Uniview, Dahua, and other vendors. Wisenet WAVE Professional offers native codec optimization for Hanwha Wisenet cameras, but non-Hanwha cameras still integrate and record normally.
Q: What happens if a drive fails?
A: Under RAID 5, a single drive failure does not stop recording or playback. The remaining drives continue to operate using parity data. Replace the failed drive (hot-swappable front-facing slot) and the RAID automatically rebuilds without downtime. RAID 6 protects against two simultaneous drive failures; RAID 0 provides no protection and loses all data if any drive fails.
Q: Is Wisenet WAVE included, or do I purchase it separately?
A: Four Professional licenses come pre-installed and pre-activated with the WRR-P-S204S-112TB. No separate purchase or activation code required. Additional Professional or Lite licenses can be purchased separately if you need to support more simultaneous users or additional sites.
Q: How does H.265 compression affect storage life and retention?
A: H.265 reduces file size 40–60% compared to H.264 at equivalent image quality. On the 87TB usable space, this means you can record significantly more camera-days before drives fill and archive begins. Exact retention depends on resolution, frame rate, and scene complexity (high motion uses more bits).

The WRR-P-S204S-112TB targets deployments where you're recording dozens of concurrent streams 24/7 and need the math to work for months of retention without running out of rack space or power budget. The 470 Mbps sustained throughput is the key number here—it's designed to absorb peak load without frame drops, which matters far more than theoretical maximum specs when you're managing real-world mixed-resolution networks.
Technical Highlights:
- 470 Mbps Sustained Throughput: Translates directly to 40–60 concurrent 4K (5MP) streams or 100+ 1080p streams without frame loss. This ceiling is realistic for enterprise deployments; undersized recorders force you to choose between live analytics and recorded integrity.
- H.265 Compression at 87TB Usable: Cuts storage requirements nearly in half versus H.264. On an 87TB recorder recording 24/7, that efficiency extends retention from, say, 60 days to 120 days—or doubles the number of concurrent streams you can record at the same retention window.
- Hot-Swappable Drive Bays + RAID 5/6 Protection: Single or dual drive failure doesn't interrupt recording. Replace a failed drive, RAID rebuilds automatically in the background. Critical for operations where any NVR downtime cascades into compliance gaps or investigation delays.
- Wisenet WAVE Professional Pre-Licensed (4 Seats): Saves roughly $400–600 in separate VMS licensing and eliminates the dependency on a separate server. If you're deploying 20+ sites, this per-unit pre-licensing adds up fast.
Deployment Considerations:
- Network Bandwidth: 470 Mbps sustained is the ingestion ceiling. Confirm your network uplink, switch ASIC capacity, and PoE switch power budget can sustain that load. A single oversubscribed switch uplink will bottleneck the entire system.
- RAID Overhead Trade-offs: RAID 5 reserves one drive's space for parity (87TB usable from 112TB raw). RAID 6 reserves two, dropping usable to roughly 75TB. The protection is worth the cost if drive failure frequency or downtime risk justifies it; RAID 0 maximizes capacity but means total data loss on any single drive failure.
- Power and Thermal Requirements: A fully loaded 2U rackmount NVR draws significant power and heat. Verify your rack's PDU capacity, UPS support, and cooling infrastructure before installation. Undersized PDUs or ventilation will throttle performance or trigger thermal shutdowns during sustained recording peaks.
Best suited for large retail, campus, logistics, or industrial environments where you're operating 50+ cameras from a single data center NVR and retention requirements are measured in months, not days. If your deployment is 10–20 cameras with 14–30 day retention, a smaller model will cost less and require simpler power/cooling infrastructure.
