WizSense + AcuPick · 5-Series · 64-Channel · 8-HDD RAID · 2U
The Dahua DHI-NVR5864-AI/ANZ is a 64-channel 5-Series WizSense AI NVR with AcuPick, eight SATA bays, RAID 0/1/5/6/10 support, dual Gigabit NICs, dual HDMI + dual VGA outputs, and a 2U rack chassis built for long-retention enterprise installs. Record up to 32 MP per channel, run AcuPick across up to 32 channels, drive a 64-channel split on the main monitor, and scale storage to roughly 128 TB on-board with hardware RAID protection.
This is the official Australia / NZ-market SKU (the AI/ANZ suffix). It's a headend NVR with no built-in PoE — cameras connect through an external PoE switch or your existing managed network. Internal 100–240 VAC universal PSU and a local 3-year warranty backed by CCTV Guru in Sydney. Designed for casinos, transport hubs, hospitals, government and any site that needs RAID-protected storage with 90+ days of retention on 64 cameras. AcuPick, N+M cluster, iSCSI and ONVIF 23.12 are enabled by Dahua's V5 firmware (current factory ship as of 2025).

Eight surveillance-grade bays
Drop in up to eight WD Purple, Seagate SkyHawk or equivalent surveillance HDDs (each up to 16 TB) — months of 64-channel recording without touching network storage. Hot-swap behind the front door for quick maintenance.
RAID 5 / RAID 6 for redundancy
Survive single-drive (RAID 5) or dual-drive (RAID 6) failures with zero footage loss. Rebuilds run in the background while recording continues — ideal for casinos, government and compliance-driven installs.
RAID 10 for performance + safety
Mirror-of-stripes configuration combines RAID 0's throughput with RAID 1's redundancy — useful when the NVR is also a fast playback workstation for the control room.
eSATA + iSCSI expansion
External SATA archive port plus iSCSI network-storage support — scale beyond 128 TB without rebuilding the recorder. Run hot-tier on the eight on-board RAID bays, archive-tier on iSCSI / eSATA.
AcuPick on up to 32 channels — enterprise-scale search
AcuPick Channels
Up to 32 ch · 1 event / channel / sec
Search Method
Image + attribute · front + back AI
Search by reference image
Click any person or vehicle in recorded video, hit AcuPick, and the NVR scans the active 32 channels for matches across hours, days or weeks — clothing colour, body shape, vehicle make / model / colour / direction included.
Front- + back-end intelligence
Camera-side AI extracts target attributes during recording; NVR-side AI runs the comparison. Higher accuracy than recorder-only search and orders of magnitude faster than human review.
Investigations finish in minutes
Find a suspect across the AcuPick-active channels and weeks of RAID-protected footage in a single search. Particularly valuable for police investigations, insurance disputes, and post-incident review.
ANPR + SMD Plus on all 64
While AcuPick covers up to 32 channels, ANPR by camera, SMD Plus by camera and perimeter protection by camera all scale across every connected camera up to 64 — site-wide intelligence with no channel left behind.

NVR5864 vs the family — how it compares
The 5864 (this model) is the storage flagship of the 5-Series AI/ANZ NVR range — double the HDD count of the 5464, hardware RAID 0/1/5/6/10, and a 2U chassis with extra alarm outputs and serial ports. Choose this when retention, redundancy or compliance-grade storage matters more than the smaller 1.5U footprint. For 64 channels in a smaller 1.5U chassis with 4 HDDs, step down to the 5464.

Frequently asked questions
What's the real benefit of RAID over disk groups?
Disk groups (on the 5464) protect against single-drive failures by warning you and isolating the bad drive — but you lose the recordings on that drive. RAID 5 and RAID 6 mathematically distribute parity across all drives, so a single (RAID 5) or even dual (RAID 6) drive failure causes zero footage loss. Compliance-driven sites (banks, casinos, healthcare, government) often require RAID for this reason.
Should I run RAID 5, RAID 6 or RAID 10?
RAID 5 (single-disk redundancy) gives 7 × 16 TB ≈ 112 TB usable across 8 × 16 TB drives — the typical default for surveillance. RAID 6 (dual-disk redundancy) gives ~96 TB usable but survives two simultaneous failures — recommended for critical sites. RAID 10 (mirror-of-stripes) gives ~64 TB usable but extremely fast playback — useful when the NVR drives the control-room wall directly.
Does this NVR really support AcuPick?
Yes. Dahua's V5 firmware (binary DH_NVR5XXX-EI_MultiLang_V5.001.0000000.0.R.251220 or later) enables AcuPick on the AI/ANZ unit alongside N+M cluster, iSCSI and ONVIF 23.12. The firmware is published on Dahua AU's official product page for this model and ships from CCTV Guru with V5 installed. Older 2023-vintage datasheets predate this firmware, which is why some online documentation doesn't mention AcuPick.
Why is AcuPick capped at 32 channels when the NVR supports 64?
AcuPick is heavy on AI-chip resources — running attribute extraction and image-search against 64 channels simultaneously isn't possible on the current 5-Series silicon. You choose which 32 of the 64 channels run AcuPick (the rest still record, and still get ANPR / SMD Plus / perimeter via camera-side AI).
Why doesn't it have built-in PoE?
The 5864 is a headend NVR for sites with managed PoE switches. Sixty-four cameras through fixed PoE ports would need a 3–4U chassis with much higher power draw. Most 64-camera installs already have a switching layer, and dedicated PoE switches give you better cable layout, VLANs and redundancy than fixed-port PoE.
How much storage do I need for 64 cameras at 90 days retention?
For 64 × 4 MP cameras at H.265+ on motion-record, expect ~100–120 TB for 90 days. Eight 16 TB surveillance-grade drives (WD Purple Pro, Seagate SkyHawk AI) in RAID 5 gives ~112 TB usable — exactly the right size. RAID 6 across the same 8 drives gives ~96 TB usable with two-disk redundancy.
Is the DHI-NVR5864-AI/ANZ NDAA Section 889 compliant?
No. Dahua products are not currently NDAA Section 889 compliant. If NDAA compliance is required (federal, government or defence installs), choose a Uniview, Hanwha, Axis, Bosch or IDIS NVR instead — CCTV Guru can recommend an equivalent.
Can it be rack-mounted?
Yes — 2U / 440 mm wide fits a standard 19-inch rack with ears (rack ears sold separately). At 6.4 kg empty (without HDDs), plan for ~13–15 kg fully loaded with eight drives.
