Hanwha PRN-3200B4 vs Hanwha PRN-3200B2: Specification Comparison
Both the PRN-3200B4 and PRN-3200B2 are Hanwha Wisenet 32-channel 8K AI NVRs running embedded Linux, sharing the same 400 Mbps recording bandwidth, H.265/H.264/MJPEG codec support, dual HDMI outputs, and identical camera input ceiling of 32 channels at up to 32MP. The primary decision axis between them is physical scale: storage bay count, RAID array capacity, chassis size, and power draw. Buyers choosing between these two units are essentially deciding how much on-board storage headroom and redundancy depth their deployment requires.

Which NVR gives you more on-board storage capacity and RAID protection depth?
The PRN-3200B4 is equipped with 16 SATA HDD bays supporting drives up to 10 TB each, yielding a maximum raw capacity of 160 TB in non-RAID mode. Its RAID implementation supports RAID-5 and RAID-6 across two independent arrays of up to 8 HDDs each (8 HDD × 2 arrays), enabling dual-parity redundancy with significant usable capacity after overhead. Drives are hot-swappable, reducing downtime during maintenance.
The PRN-3200B2 carries 8 SATA HDD bays with the same 10 TB per-drive ceiling, capping raw capacity at 80 TB in non-RAID mode — exactly half the PRN-3200B4. Its RAID-5/6 implementation is confined to a single array, meaning one failure domain rather than two. Hot-swap capability is not explicitly stated in the provided specifications for the B2.
For high-retention deployments — long-loop recording, multi-site archiving, or high-resolution camera farms — the PRN-3200B4's 160 TB ceiling and dual-array RAID configuration provide substantially more headroom. The PRN-3200B2's 80 TB single-array design suits mid-scale sites where storage density is not the primary driver.
How do chassis size, power consumption, and playback bandwidth differ between the two units?
The PRN-3200B4 measures 440.0 × 132.0 × 571.1 mm and weighs approximately 13.6 kg (HDDs excluded). Maximum power draw is rated at 285 W with all 16 HDDs installed (972.5 BTU). It occupies a larger rack footprint commensurate with its 16-bay chassis. Playback bandwidth is specified at a maximum of 64 Mbps supporting up to 32 channels locally and 16 channels per remote user simultaneously.
The PRN-3200B2 is meaningfully more compact at 438 × 86 × 434.9 mm and weighs approximately 9.1 kg (HDDs excluded), consuming a maximum of 205 W with eight 10 TB HDDs installed. It draws 80 W less at full HDD load. Playback bandwidth is differentiated by storage mode: RAID mode caps at 64 Mbps, while non-RAID mode drops to a maximum of 32 Mbps — a spec distinction not present in the B4's documentation.
Space- and power-constrained installations benefit from the PRN-3200B2's smaller footprint and lower wattage. Installers should note the B2's non-RAID playback bandwidth ceiling of 32 Mbps when sizing simultaneous retrieval workloads; the B4's spec states 64 Mbps without a mode-dependent qualifier.
Are there meaningful differences in protocol support, viewer software, and AI analytics integration?
The PRN-3200B4 lists Wisenet and ONVIF as its camera-side protocols, and its full network protocol stack includes PPPoE — not listed for the PRN-3200B2. Viewer software for the B4 includes Webviewer, Smart Viewer, Wisenet mobile, and CGI/SUNAPI. Recording modes cover Normal, Dual Stream, Schedule, and Event. AI search covers Person, Face (with Wisenet AI camera), Vehicle, and License Plate, with LPR supporting English and numeric characters via Wisenet AI P/X cameras.
The PRN-3200B2 lists SUNAPI and ONVIF as camera-side protocols; Wisenet is not separately enumerated, though SUNAPI is Hanwha's proprietary API. Its viewer software omits Smart Viewer relative to the B4, listing Webviewer, Wisenet mobile, and CGI/SUNAPI. Recording modes add Bookmark compared to the B4. AI search attributes are labeled Human, Face, Vehicle, and License Plate — functionally equivalent to the B4's Person/Face/Vehicle/LP set. PPPoE is absent from the B2's protocol list.
Both units share ONVIF Profile-S compatibility, identical remote user limits (Search 3, Live Unicast 10, Multicast 20), identical mobile platform support (iOS/Android), and the same SPC-2000 controller support. The PRN-3200B4 additionally lists Smart Viewer and PPPoE. The PRN-3200B2 adds a Bookmark recording mode. Neither difference is a disqualifier for standard Wisenet ecosystem deployments; integrators relying on Smart Viewer or PPPoE WAN connectivity should specify the B4.
Which should you choose: the PRN-3200B4 or the PRN-3200B2?
Our take: The PRN-3200B4 is the stronger choice when on-board storage volume, RAID redundancy depth, or Smart Viewer integration are deployment requirements. Concretely: it provides 16 SATA bays versus the B2's 8, doubling maximum raw capacity from 80 TB to 160 TB; its RAID-5/6 spans two independent 8-HDD arrays rather than a single array; and its playback bandwidth holds at 64 Mbps regardless of RAID mode, whereas the B2 drops to 32 Mbps in non-RAID operation. The trade-off is a larger, heavier chassis (440 × 132 × 571 mm, 13.6 kg) drawing up to 285 W versus the B2's 438 × 86 × 435 mm, 9.1 kg form factor at 205 W. The PRN-3200B2 is the appropriate selection for rack-space- or power-budget-constrained sites where 80 TB of storage and a single RAID array are sufficient, and where Smart Viewer and PPPoE are not required.

Frequently Asked Questions
Which should you choose: the PRN-3200B4 or the PRN-3200B2?
The PRN-3200B4 is the stronger choice when on-board storage volume, RAID redundancy depth, or Smart Viewer integration are deployment requirements. Concretely: it provides 16 SATA bays versus the B2's 8, doubling maximum raw capacity from 80 TB to 160 TB; its RAID-5/6 spans two independent 8-HDD arrays rather than a single array; and its playback bandwidth holds at 64 Mbps regardless of RAID mode, whereas the B2 drops to 32 Mbps in non-RAID operation. The trade-off is a larger, heavier chassis (440 × 132 × 571 mm, 13.6 kg) drawing up to 285 W versus the B2's 438 × 86 × 435 mm, 9.1 kg form factor at 205 W. The PRN-3200B2 is the appropriate selection for rack-space- or power-budget-constrained sites where 80 TB of storage and a single RAID array are sufficient, and where Smart Viewer and PPPoE are not required.
Is the PRN-3200B4 or PRN-3200B2 better for larger deployments needing more on-site storage retention?
The PRN-3200B4. It supports 16 SATA bays up to 160 TB raw (non-RAID) with dual independent RAID-5/6 arrays, compared to the PRN-3200B2's 8 bays and 80 TB ceiling with a single RAID array. If your retention policy requires more than 80 TB on a single appliance, the B4 is the only option of the two that meets that requirement.
Do both NVRs support the same camera count and resolution?
Yes. Both the PRN-3200B4 and PRN-3200B2 accept up to 32 IP camera channels at resolutions ranging from CIF up to 32MP, share the same 400 Mbps maximum recording bandwidth, and decode at identical frame rates: 32MP@15fps, 12MP@30fps, and 8.3MP@120fps. Neither unit has an advantage in channel count or maximum resolution per the provided specifications.
Will the PRN-3200B2 fit in a tighter rack or equipment room where space and power are limited?
Yes. The PRN-3200B2 is 86 mm tall (versus 132 mm for the B4), shorter in depth at 434.9 mm versus 571.1 mm, lighter at 9.1 kg versus 13.6 kg, and draws a maximum of 205 W with 8 HDDs installed compared to the B4's 285 W with 16 HDDs. For installations where rack units, physical depth, or power circuit capacity are constrained, the PRN-3200B2 has a materially smaller physical and electrical footprint.
