Series 2 · NVR NEXT · WizSense + AcuPick · 32-Channel · 16 HP-PoE · 4-HDD · 1.5U
The Dahua DHI-NVR5432-16HP-AI/ANZ-S2 is a 32-channel, 1.5U WizSense network video recorder built for professional Australian IP CCTV systems. It combines the NVR NEXT interface, AcuPick search, 32 MP camera support, 448 Mbps incoming/recording/outgoing bandwidth with AI disabled, four SATA bays and 8K HDMI output.
Sixteen integrated IEEE 802.3af/at PoE ports provide a 200 W total PoE budget, with up to 25.5 W available per port; ports 1–8 also support Dahua ePoE. The remaining 16 IP channels can be connected through the network using an external PoE switch. This is the official Australia/New Zealand AI/ANZ-S2 model, supplied with Australian stock, local support and CCTV Guru's 3-year warranty.
NVR NEXT — the redesigned Dahua NVR interface

NVR NEXT modular GUI
Dahua's NVR NEXT interface uses a modular design to simplify navigation and streamline live view, playback, search and AI workflows for small and medium-sized business installations.
AcuPick native from day one
No firmware upgrade required — AcuPick ships as a baseline feature on the S2 platform. Click any person or vehicle in recorded video and the NVR scans up to 4 channels of NVR-side AcuPick + all-channel camera-side AcuPick for matches.
ONVIF 25.06 with Profile M
Latest ONVIF version support including Profile M — the new metadata profile that lets third-party VMS platforms consume AI events (people-count, ANPR, perimeter triggers) natively without proprietary integration work.
16 High-Power PoE+ ports + 4-HDD storage
PoE
16 × HP · 200 W · 1–8 ePoE 800 m
Storage
4 SATA · up to 80 TB on-board
200 W High-Power PoE budget
The "HP" in the model name — 33% more PoE headroom than the older 5432-16P's 150 W. 25.5 W per port maximum, which comfortably runs 16 IR-heavy bullets, active-deterrence turrets or mini PTZs without the usual per-port derating.
ePoE support on ports 1–8
Ports 1–8 support Dahua ePoE for compatible long-distance camera links. Actual cable distance and data rate depend on the camera, cable quality and installation conditions; ports 9–16 support standard IEEE 802.3af/at PoE.
4 SATA bays · up to 80 TB
Four SATA interfaces support up to 20 TB per drive, for up to 80 TB of installed capacity. Retention varies with camera resolution, frame rate, bitrate, compression, scene activity and recording schedule; ask CCTV Guru for a project-specific storage calculation.
iSCSI + eSATA expansion
Native iSCSI for network-attached storage plus one eSATA port for the optional Dahua ESS1504C 4-bay eSATA extension cabinet. Scale storage well beyond 80 TB without rebuilding the recorder.
AcuPick + face recognition — one-click investigation
Face Database
20 DBs · 30,000 images · 3.75 GB
Face Recognition
24 ch @ 24 fps image stream
Face Recognition at scale
24 channels of camera-side face detection feeding NVR-side recognition at 24 face snapshots/sec (up from 16 fps on the older 5-Series), or 4 channels of full FD+FR by the recorder at 24 fps. Twenty face databases hold up to 30,000 images (50% larger than the previous 5-Series).
Perimeter Protection (8 ch by NVR)
8 NVR-side channels of tripwire and intrusion analytics — double the older 5-Series capacity — with 10 IVS rules per channel and human/vehicle secondary filtering. Every camera adds all-channel perimeter via camera-side processing.
SMD Plus on 16 channels by NVR
Smart Motion Detection Plus runs a deep-learning second pass on 16 NVR-side channels — half the entire licence — classifying targets as person or vehicle so only real events make it to your phone or VMS.
Video Metadata by NVR (4 ch · 22 attributes)
NVR-side metadata extraction is available on four channels, with 22 searchable human and vehicle attributes including clothing colour, hat, bag, age, gender, vehicle model, colour and licence-plate details.
ANPR by camera (all 32 channels)
Pair with Dahua ANPR cameras for full 32-channel licence-plate recognition feeding a 20,000-plate database with blocklist / allowlist control. Ideal for carparks, fleet yards, gate management and multi-site ANPR.
AcuPick + attribute search
AcuPick helps locate matching people or vehicles in recorded video, while metadata and face/plate databases support more structured investigations. Available channels depend on whether analytics run on the recorder or compatible cameras.
PPE Detection + Smart Object & Sound — safety-compliance AI
PPE Detection (camera-side)
Detect safety attributes — helmets, safety vests, face masks, glasses, top/bottom colour — and trigger compliance or non-compliance alarms based on the site's requirements. Essential for construction, mining, warehousing, food-processing and any site with mandated PPE rules.
Smart Object Detection
Supports compatible Dahua cameras with smart object detection. Available object rules and alarm actions depend on the connected camera model and its firmware.
Smart Sound Detection
Supports smart sound detection from compatible Dahua cameras. Supported sound events and alarm actions depend on the camera model, microphone and firmware.
Stereo analysis + crowd distribution
Pair with stereo cameras to detect people falling, climbing fences or walking into restricted zones. Crowd distribution maps footfall density in real time — useful for shopping-centre queue management and event venues.
People counting + heat map
Camera-side people counting for retail and site occupancy; heat map visualises dwell zones as colour overlays. Export data for BI dashboards or Dahua DSS Pro reporting.
Vehicle density
Real-time vehicle-density metrics for carpark utilisation, gate throughput and traffic flow. Combine with ANPR for full carpark automation with entry/exit LPR + occupancy monitoring.

32 MP recording · 448 Mbps bandwidth · 8K HDMI
Up to 32 MP per channel
True 8K-class camera input — records 32 MP, 24 MP, 16 MP, 12 MP, 8 MP (4K), 6 MP, 5 MP or 4 MP IP cameras from Dahua or any ONVIF brand. All 32 channels share the 448 Mbps recording bandwidth.
448 Mbps recording bandwidth
17% higher than the older 5432-16P (384 Mbps). Comfortable for 32 cameras at 6-8 MP each on H.265+, or a mix of 32 MP flagship cameras and 4 MP sub-stream feeds.
8K HDMI output
7680 × 4320 native output on HDMI — future-proof for 8K control-room monitors and video walls. Second HDMI + dual VGA drive independent secondary displays with heterogeneous or simultaneous routing.
40-channel 1080p decoding
Decode 40 × 1080p tiles simultaneously (up from 32 on the older 5432-16P) — extra headroom for spot monitors and secondary displays.
36-channel split on main monitor
Main monitor supports 1 / 4 / 8 / 9 / 16 / 25 / 36-split layouts (sub monitor up to 16). Drag-and-drop channel reorder with instant playback from thumbnail.
Smart H.265+ for half the storage
AI-tuned H.265+ encoding cuts bitrate on static background pixels while preserving detail on moving targets — roughly half the storage and bandwidth of standard H.264.
