Hanwha PRN-6400DB4 vs i-PRO NX400/27000T3: Specification Comparison
Both the Hanwha PRN-6400DB4 and the i-PRO WJ-NX400/27000T3 are rack-mount embedded Linux NVRs in the 64-channel enterprise class, supporting ONVIF and H.265 compression. This comparison covers their recording bandwidth and resolution ceilings, storage architecture and redundancy, and integration and AI analytics capabilities — the three dimensions most likely to drive a purchasing decision at this channel count and deployment scale.

Which NVR delivers higher recording bandwidth and maximum camera resolution?
The PRN-6400DB4 is specified at a maximum recording bandwidth of 400 Mbps and supports camera resolutions up to 32MP, with decoding capable of 32MP at 15 fps or 1080p at 480 fps via dual HDMI outputs (4K@30Hz + 1080p@60Hz). Simultaneous playback across up to 112 channels (64 local, 16 per remote user) is documented, with a maximum playback bandwidth of 64 Mbps across 64 channels.
The WJ-NX400/27000T3 specs state a maximum resolution of 4K (3840×2160, i.e., 8MP) and a speed figure of 3 Mbps — which appears to represent a per-channel or specific-mode throughput figure rather than aggregate recording bandwidth; no aggregate recording bandwidth spec is provided in the supplied data. Maximum frame rate is listed as 60 fps per camera. The resolution ceiling is substantially lower than Product A's 32MP.
For deployments requiring multi-megapixel cameras above 8MP — such as 12MP or 32MP panoramic or multi-sensor units — only the PRN-6400DB4 provides documented support. The i-PRO unit's bandwidth ceiling is not comparable from available specs.
How do the two units differ in storage capacity, expansion, and data redundancy?
The PRN-6400DB4 provides 16 hot-swappable SATA HDD bays supporting drives up to 10TB each, yielding a documented maximum of 160TB raw capacity. RAID 5 and RAID 6 are supported across two arrays of 8 HDDs each, and iSCSI external storage expansion is specified. An N+1 failover redundancy mode and Automatic Recovery Backup (ARB) are explicitly listed.
The WJ-NX400/27000T3 ships with 27TB pre-installed (nine 3TB drives per the SKU designation) and supports RAID 0, 1, 5, 6, and 10. No maximum expandable raw capacity figure, hot-swap capability, iSCSI support, or N+1 failover specification is provided in the supplied data. Local storage via microSD is listed as a separate spec, suggesting edge-clip or supplemental use.
The PRN-6400DB4 offers a documented raw capacity ceiling six times higher than the i-PRO unit's pre-installed 27TB, with explicit hot-swap, iSCSI, and N+1 failover specs. The WJ-NX400/27000T3's maximum expandable capacity and hot-swap status are not determinable from the provided specifications.
Which unit provides broader integration, AI analytics, and remote management capabilities?
The PRN-6400DB4 supports ONVIF Profile S alongside Hanwha's proprietary SUNAPI/Wisenet ecosystem, PTZ control for up to 300 presets, P2P QR-code setup, fisheye dewarping (local 1CH plus CMS), and AI search for person, face, vehicle, and license plate attributes — with LPR supporting English and numeric plates on Wisenet AI/P/X-series cameras. Remote access allows up to 10 live unicast and 20 multicast users; web viewer supports Windows 10 and macOS 10.13 via Chrome, Edge, and Safari. Security features include 802.1x, IP filtering, device certificate, and signed firmware.
The WJ-NX400/27000T3 specifies ONVIF Profile S compatibility and i-PRO IP camera compatibility, with PTZ control covering pan/tilt, zoom, focus, brightness, and up to 256 presets. Audio compression covers G.711 and G.726 ADPCM at 32 kbps with RCA output. Alarm I/O is specified at up to 32 inputs and 4 reset inputs. No AI analytics, remote user count limits, web viewer OS/browser support, or advanced security features (802.1x, signed firmware) are listed in the provided specs.
The PRN-6400DB4 documents a more complete integration and security feature set including AI search, higher PTZ preset count (300 vs. 256), explicit multi-user access limits, and firmware integrity controls. The WJ-NX400/27000T3's integration capabilities beyond ONVIF and basic PTZ are not determinable from available data.
Which should you choose: the PRN-6400DB4 or the NX400/27000T3?
Our take: The PRN-6400DB4 is the stronger choice when maximum throughput, high-resolution camera support, and on-box AI analytics are required. Three concrete spec deltas stand out: recording bandwidth is documented at 400 Mbps for the Hanwha versus an unspecified aggregate for the i-PRO (only a 3 Mbps per-mode figure provided); maximum camera resolution is 32MP on the PRN-6400DB4 versus 4K/8MP on the WJ-NX400/27000T3; and maximum raw storage is 160TB (16 hot-swap bays) versus 27TB pre-installed with no documented expansion ceiling for the i-PRO. The PRN-6400DB4 fits enterprise deployments running high-megapixel or multi-sensor Wisenet cameras and requiring on-box AI search with RAID redundancy and N+1 failover. The WJ-NX400/27000T3 may suit mid-scale i-PRO-centric environments where 27TB pre-installed capacity suffices and a 4K resolution ceiling is acceptable, but critical specs including aggregate bandwidth and expansion limits are absent from provided data and should be verified before purchase.
