Hanwha XRN-1620B2 16-Channel 4K Network Video Recorder

The Hanwha XRN-1620B2 is a 16-channel network video recorder engineered for mid-to-large surveillance deployments where high-resolution evidence preservation and system continuity are non-negotiable. This unit supports input resolution up to 32MP and delivers 140Mbps aggregate recording bandwidth—enough bandwidth headroom to capture full-frame multi-stream video without forcing frame-rate compromises or codec trade-offs that would degrade forensic value. The XRN-1620B2 is purpose-built for retail chains, warehouses, transportation hubs, government facilities, and enterprise campuses where storage density, redundancy, and long-term evidence integrity matter.

Key Features

• 16-channel input with up to 32MP resolution support: Accommodates ultra-high-resolution sensors (4K, 5MP, and beyond) without compression-forced degradation. H.265, H.264, and MJPEG codec support means you're not locked into one compression strategy—H.265 cuts storage requirements roughly in half compared to H.264 on the same scene, a tangible cost savings when running 24/7 recording across all 16 channels.
• 140Mbps recording bandwidth: Delivers sustained throughput for simultaneous high-bitrate streams. This prevents the bottleneck that occurs when you daisy-chain multiple high-resolution cameras on undersized NVRs—all 16 channels record at full quality without visible frame-rate stuttering or quality reduction during peak traffic.
• Up to 80TB total storage capacity across 8 SATA HDD slots: Supports drives up to 10TB each. That translates to multi-month retention of 16-channel 4K or mixed-resolution video depending on compression codec and frame rates. Larger capacity per drive reduces the number of mechanical devices in the system, lowering failure probability and power consumption.
• Dual monitor output: 4K HDMI and FHD VGA: Enables hybrid control room setups where modern 4K displays coexist with legacy infrastructure. No need to replace working VGA monitors or buy adapter chains—both outputs run simultaneously, supporting different refresh rates and resolutions.
• N+1 failover and Automatic Redundancy Backup (ARB): If the primary NVR fails, recording and playback automatically transfer to a secondary unit without manual intervention. This eliminates the gap in evidence capture that would occur during traditional manual failover, critical for compliance and incident reconstruction in high-security deployments.
• Multi-source event triggering: Alarms, video loss, motion detection, and camera analytics (via Wisenet AI metadata) can independently trigger pre/post recording windows. Pre-recording buffers ensure you don't miss the critical frames before an alarm condition—footage begins capturing seconds before the trigger event.
• Up to 4 concurrent users with 32Mbps playback bandwidth per user: Multiple investigators can simultaneously search and review recorded footage without waiting for single-user playback queues. Simultaneous 64-channel playback (16 local, 16 per remote user) means collaborative incident review doesn't require taking the system offline or stalling operations.
• ONVIF and SUNAPI protocol support: Integrates with third-party VMS platforms (Milestone XProtect, Genetec, etc.) and third-party IP cameras from other manufacturers. You're not forced into an all-Hanwha ecosystem—mix-and-match cameras based on deployment needs, not vendor lock-in.
• 16-channel 2-way audio communication: Built-in audio codec support (G.711, G.726, AAC) enables two-way voice between remote users and on-site microphones. Useful for remote facility management, warehouse floor communication, or incident de-escalation scenarios.
• Wisenet AI metadata search compatibility: Compatible with Hanwha's AI analytics—search footage by object type, person, vehicle, or behavioral anomalies rather than scrubbing through hours of raw video. Dramatically reduces forensic investigation time when handling large case volumes.
• P2P connectivity with QR code setup: Simplified remote access without static IP or port forwarding headaches. Scan a QR code on the unit, connect via mobile app. Useful for multi-site operators who need rapid deployment or field access without IT infrastructure overhead.
• iOS and Android mobile support: Live 16-channel viewing and 4-channel playback on smartphones. Allows site managers or security personnel to monitor or review incidents from the field without returning to the control room.

Integration & Compatibility

Network protocols include IPv4, IPv6, TCP/IP, UDP/IP, RTP, RTSP, ONVIF Profile-S, and SUNAPI, ensuring compatibility with most enterprise IP camera ecosystems and VMS platforms. Connectivity includes 2x Gigabit Ethernet (LAN/WAN separation supported), 4 alarm inputs, 2 alarm outputs, and 3 USB ports (front 2x USB 2.0, rear 1x USB 3.0) for evidence export and configuration management. Security features include IP filtering, user access logging, 802.1x network authentication, device certificates, and signed firmware—table-stakes for healthcare, financial, and government deployments where audit trails and tamper-evidence are regulatory requirements.

Power consumption is 130W at 100-240VAC, modest for a 16-channel unit. Operating temperature range is 0°C to +40°C (32°F to 104°F), suitable for most climate-controlled data centers and secure server rooms; extended environmental hardening would require additional enclosure work.

When to Choose a Different Model

If you need more than 16 channels, consider larger-capacity Hanwha NVR variants in the XRN series. If your deployment requires lower bandwidth (single-stream recording, legacy SD cameras), a smaller-channel NVR will reduce power and cooling costs. If you need built-in video analytics without Wisenet AI licensing, evaluate whether post-event metadata search justifies the software subscription model in your operational budget.

Frequently Asked Questions

Q: What's the maximum recording duration on the XRN-1620B2 with 80TB storage?

A: Duration depends on resolution, frame rate, and codec. Using H.265 at 4K 30fps across all 16 channels, you'll achieve roughly 30–40 days of continuous recording with full 80TB capacity. H.264 reduces that to 15–20 days. Mixed-resolution deployments (some 4K, some 1080p) extend retention proportionally.

Q: Does the XRN-1620B2 support ONVIF Profile S cameras?

A: Yes. ONVIF Profile-S is fully supported, and Profile-T (PTZ) is also compatible. This means you can integrate cameras from other manufacturers without vendor lock-in.

Q: Can I use the XRN-1620B2 in a failover configuration?

A: Yes. The N+1 failover and Automatic Redundancy Backup (ARB) features allow a secondary unit to take over if the primary fails, with no manual intervention required. This is designed for surveillance-critical deployments where evidence loss is unacceptable.

Q: What's the playback bitrate, and can multiple users review footage simultaneously?

A: Up to 4 concurrent users can access the system, each with 32Mbps playback bandwidth. You can simultaneously play back 16 channels locally and 16 channels per remote user (64 total playback channels across all sessions).

Q: Does the XRN-1620B2 support H.265 compression?

A: Yes. H.265 (HEVC) is fully supported alongside H.264 and MJPEG. H.265 cuts storage consumption by roughly 40–60% on typical surveillance scenes, a meaningful savings over years of 24/7 operation.

Q: Can I search recordings using AI metadata from Hanwha cameras?

A: Yes. The XRN-1620B2 is compatible with Wisenet AI metadata. If your cameras support AI object detection or behavioral analytics, you can search by person, vehicle, or event type rather than manual scrubbing through hours of footage.

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

The XRN-1620B2 represents Hanwha's enterprise-focused approach to mid-scale NVR deployment. The 140Mbps bandwidth paired with H.265 codec support delivers efficient storage utilization without sacrificing frame rate or resolution fidelity—a critical balance when you're managing budgets for multi-year retention across dozens of cameras. The dual-output display system (HDMI 4K + VGA FHD) addresses hybrid control room environments where legacy and modern displays must coexist, eliminating the need for expensive KVM switchers or wholesale control room refresh cycles.

Technical Highlights:

• H.265 compression with 140Mbps bandwidth: Reduces storage footprint 40–60% versus H.264 on the same scenes. At 80TB maximum capacity, this translates to 30–40 days of true 4K recording across all 16 channels—meaningful for organizations managing long-term evidence retention without quarterly drive upgrades.
• N+1 failover and ARB redundancy: Automatic failover to a secondary unit eliminates the evidence gap that occurs during manual failover scenarios. In incident reconstruction, missing 30 minutes of footage can invalidate an entire investigation. This feature alone justifies deployment in surveillance-critical operations.
• Multi-source event triggering with pre/post recording: Alarms, motion, analytics, or video loss independently trigger pre-event buffering. You capture the critical frames leading up to an alarm condition, not just what happens after. In retail loss prevention, this is the difference between identifying a suspect's entry point and having only the theft itself on record.
• ONVIF Profile-S and SUNAPI support: Full third-party camera and VMS integration. You're not locked into an all-Hanwha ecosystem—deploy best-of-breed sensors and integrate with platforms like Milestone, Genetec, or Axis Camera Station without middleware or API workarounds.
• Wisenet AI metadata search: If your cameras support Hanwha AI analytics, search by object type or behavior pattern rather than frame-by-frame review. A 30-day investigation window on 16 channels shrinks from weeks of manual scrubbing to hours of targeted forensics.

Deployment Considerations:

• Storage planning is critical: 80TB maximum capacity with H.265 delivers 30–40 days at 4K 30fps. If your policy requires 90+ day retention, you'll need external archival strategy (secondary NAS, cloud export) or a larger system—don't assume the maximum capacity translates directly to your retention SLA.
• Control room dual-output is fixed: The HDMI 4K output and VGA FHD output run in parallel, not switchable. If you need three independent monitor outputs, you'll need an external switcher or a second display management appliance.
• Failover requires infrastructure: N+1 redundancy demands a second XRN-1620B2 and synchronized storage configuration. Single-unit deployments don't benefit from ARB. Budget for the secondary unit and network configuration before committing to failover SLAs.

The XRN-1620B2 is purpose-built for warehouse, retail, and government deployments where evidence integrity, multi-user concurrent access, and long-term retention are operational requirements, not nice-to-haves. It's the right choice when your investigation and compliance teams need full resolution, rapid search, and zero tolerance for evidence loss—not when you're optimizing for lowest cost per camera.
