WizSense + AcuPick · 5-Series · 32-Channel · 4-HDD · 1.5U
The Dahua DHI-NVR5432-AI/ANZ is a 32-channel 5-Series WizSense AI NVR with AcuPick on all 32 channels, four SATA bays, dual Gigabit NICs, dual HDMI + dual VGA outputs, and a 1.5U rack chassis built for enterprise-scale installs. Record up to 32 MP per channel, scale storage to roughly 80 TB on-board (plus eSATA and iSCSI expansion), and split the live wall across up to 36 channels on the main monitor.
This is the official Australia / NZ-market SKU (the AI/ANZ suffix). It's a headend NVR with no built-in PoE — connect your cameras through an external PoE switch (or a dedicated PoE injector chain) and use the recorder for AI, storage and the control-room wall. Shipped with regional firmware, an internal 100–240 VAC universal PSU and a local 3-year warranty backed by CCTV Guru in Sydney.
AcuPick on all 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 all 32 channels for matches across hours or days — 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 32 cameras and three weeks of footage in a single search. Particularly valuable for police investigations, insurance disputes, and post-incident review.
Beyond Quick Pick
AcuPick is the next generation of Dahua's Quick Pick — more attributes, more accuracy, and supports both people and vehicles natively. Exclusive to the 5-Series NVR family.

NVR5432 vs the family — where it sits
The 5432 is the enterprise headend in our Dahua range — twice the channel count of the 5216, twice the HDD bays, twice the network ports, and the only model with a 36-channel split and a 12 V alarm-output feed. The trade-off is the absence of built-in PoE: cameras must be powered through an external switch. Choose the 5216 instead if you want PoE built into the recorder; choose the 5432 (this model) when you're running more than 16 cameras through an existing managed network.

Frequently asked questions
Why doesn't the NVR5432 have built-in PoE?
The 5432 is a headend NVR designed for sites that already run a managed network. Cameras connect through an external PoE switch (Dahua's own PoE switches, or any IEEE 802.3af/at managed switch). This gives you VLAN segregation, redundant network paths and far better scaling than fixed 16-port PoE NVRs. If you'd prefer all-in-one with PoE built into the recorder, choose the 5216-16P-AI/ANZ instead.
How big a PoE switch do I need for 32 cameras?
Allow about 7-15 W per camera for most Dahua WizSense bullets/turrets, more for active-deterrence units and PTZs. A 24-port PoE+ switch with 370–500 W of budget will run 32 typical cameras comfortably; a 48-port managed PoE+ switch is more headroom and gives spare ports for VoIP, APs and APs. CCTV Guru can quote a complete switch + NVR bundle.
What is AcuPick and what do I need for it?
AcuPick is Dahua's next-generation attribute-and-image search — it extracts rich target attributes (clothing, body shape, vehicle make/model/colour/plate, direction) at the camera AND the NVR, then lets you search across all 32 channels by reference image or combined attributes. You need Dahua's AcuPick-ready cameras (typically TiOC PV and 5-Series WizSense Plus IPC families). Standard WizSense cameras still record and recognise faces but the full AcuPick depth requires paired AcuPick IPCs.
What's the dual NIC for?
Two independent Gigabit RJ-45 ports — use them for VLAN segregation (camera VLAN on NIC1, management/uplink VLAN on NIC2), or bond them for active-passive failover (NIC2 takes over if NIC1's switch port dies), or load-balance for combined throughput. Configured from the local GUI or web interface.
How much storage do I need for 32 cameras?
For 32 × 4 MP cameras at H.265+ on motion-record, allow ~25-35 TB for 30 days of retention. Four 8 TB or 10 TB surveillance-grade drives (WD Purple, Seagate SkyHawk) covers most use cases with disk-group protection. If on-board capacity isn't enough, iSCSI lets you expand onto network-attached storage or eSATA onto external archive arrays.
Is the DHI-NVR5432-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 — 1.5U / 440 mm wide fits a standard 19-inch rack with ears (rack ears sold separately). It can also sit on a desk or shelf if you've allocated cabinet space. At 4.74 kg empty (without HDDs), plan for around 7-8 kg fully loaded with four drives.
What's the 12 V alarm output for?
One of the 6 alarm outputs is a direct 12 V 1 A power feed — drive a siren, strobe light or electric strike directly without needing an external relay or power supply. The other 5 outputs are dry-contact relays you can wire to anything that takes a NO/NC trigger.
