Product SKU: DHI-NVR5432-AI/ANZ-S2
Product Overview
The Dahua DHI-NVR5432-AI/ANZ-S2 is a 32-channel, 1.5U WizSense network video recorder designed for commercial sites and distributed CCTV networks that use separate PoE switching. With no built-in PoE ports, cameras connect through suitable external network switches, allowing power and network infrastructure to be positioned closer to separate buildings, floors or operational areas. Four SATA bays provide flexible recording storage, while dual Gigabit Ethernet ports support structured network configurations. The recorder accepts compatible IP cameras up to 32MP, provides up to 448Mbps incoming, recording and outgoing bandwidth when recorder-side AI is disabled, and supports 8K HDMI output. AcuPick, face analysis, video metadata, perimeter protection and SMD Plus assist with event filtering and footage investigation, while eSATA, iSCSI, N+M clustering and extensive alarm connections suit professional multi-camera systems.
Key Capabilities
Thirty-Two Camera Channels
The recorder supports up to 32 IP camera channels, providing capacity for larger sites, multiple buildings or several operational areas. Cameras connect through the site network rather than an integrated NVR PoE switch, giving installers more freedom over switch location and power planning.
AcuPick Target Searching
AcuPick combines recorder-side and compatible camera-side intelligence to help locate relevant people and vehicles within recorded footage. The recorder supports four AcuPick channels, while suitable cameras can provide AcuPick processing across all connected channels.
Four-Bay Recording Storage
Four internal SATA bays support compatible surveillance hard drives up to 20TB per disk under the stated operating conditions. This gives larger camera systems more retention flexibility than common one-bay or two-bay recorders.
Recorder-Side WizSense Analytics
Face detection, face recognition, video metadata, perimeter protection and SMD Plus can be processed by the recorder within the confirmed channel limits. Human and vehicle filtering helps operators focus on relevant events instead of reviewing every basic motion alarm.
8K Multi-Monitor Output
Two HDMI and two VGA outputs support separate local camera layouts, with HDMI resolutions reaching 7680 × 4320. Main-screen layouts can display up to 36 windows, making the NVR useful in control rooms and reception areas.
Flexible Network and Storage Integration
Dual Gigabit network ports support multi-address mode, load balancing, fault tolerance and link aggregation. eSATA, iSCSI, disk groups and N+M clustering provide additional flexibility for professional networks and supported storage arrangements.

Why Choose the DHI-NVR5432-AI/ANZ-S2
The DHI-NVR5432-AI/ANZ-S2 is better suited to distributed networks than a recorder with a fixed built-in PoE switch. External switching allows camera power, uplinks and network locations to be planned separately for each floor, building or operational zone. Four SATA bays provide substantial storage flexibility, while 448Mbps bandwidth supports demanding camera combinations when the system is configured correctly. AcuPick improves footage searching, and 16-channel SMD Plus with eight-channel perimeter protection provides useful event filtering across larger sites. Dual Gigabit ports, 8K output and extensive alarm connections further support professional installations. Available through Security Wholesalers, this model is a practical choice for buyers who prioritise network flexibility, storage capacity and AI-assisted investigation.
Buyer Decision Tips
PoE Planning Tip: This recorder does not supply power to cameras. Select suitable PoE switches or injectors separately and confirm their total power budget, uplink bandwidth, network location and redundancy requirements before installation.
AI and Bandwidth Tip: Enabling recorder-side AI reduces incoming, recording and outgoing bandwidth from 448Mbps to 200Mbps. Plan the required analytics and combined camera bitrates before commissioning the system.

- Choose a larger storage platform if: More than four internal drives or storage redundancy is required.
FAQs
- How many cameras can connect to the DHI-NVR5432-AI/ANZ-S2, and does it provide PoE?
The DHI-NVR5432-AI/ANZ-S2 supports 32 IP camera channels but does not include built-in PoE ports. Cameras must receive power through suitable external PoE switches, PoE injectors or supported local power arrangements. This makes the recorder a better fit for structured networks where camera switching is distributed across several cabinets, floors or buildings rather than concentrated at the NVR.
- What does AcuPick do on the DHI-NVR5432-AI/ANZ-S2?
AcuPick helps operators locate relevant people or vehicles within large amounts of recorded footage. The recorder supports AcuPick processing on four channels, while compatible camera-side AcuPick can operate across all channels at up to 32 targets per second. Search accuracy still depends on camera position, target visibility and correct event configuration, so AcuPick should be treated as an investigation tool rather than a guarantee that every target will be found.
- Which AI functions can the recorder perform itself?
AI by Recorder includes face detection, face recognition, human and vehicle metadata, perimeter protection, SMD Plus and AcuPick. The confirmed limits include four channels of face detection, four channels of metadata, eight channels of perimeter protection, 16 channels of SMD Plus and four channels of AcuPick. These functions use the recorder’s processing resources, so the intended combination should be planned during system design and commissioning.
- What camera resolution and bandwidth does this S2 NVR support?
The recorder accepts compatible IP cameras up to 32MP. With recorder-side AI disabled, it provides up to 448Mbps incoming, 448Mbps recording and 448Mbps outgoing bandwidth. With AI enabled, each limit becomes 200Mbps. The final camera mix should be planned around resolution, frame rate, bitrate, local display layouts and playback requirements because multiple high-resolution streams can consume the available decoding and network capacity quickly.
- How much recording storage can be installed?
The DHI-NVR5432-AI/ANZ-S2 provides four SATA bays, with each compatible hard drive supporting up to 20TB under the stated operating conditions. The supplied datasheet does not confirm pre-installed storage. Buyers purchasing through Security Wholesalers should check the selected sales configuration and calculate retention from camera count, resolution, frame rate, bitrate, compression and whether recording will be continuous, event-based or scheduled.
- What local display and playback options are available?
The recorder provides two HDMI outputs and two VGA outputs. HDMI supports resolutions up to 7680 × 4320, while VGA supports up to 1920 × 1080. HDMI 1 and HDMI 2 can show different video sources, with each VGA output mirroring its corresponding HDMI output. The NVR also supports up to 16-channel simultaneous playback and main-screen layouts of up to 36 windows.
- What are the benefits of the two Gigabit network ports?
The two Gigabit Ethernet ports support multi-address mode, load balancing, fault tolerance and link aggregation. This is useful in professional installations where camera traffic, client access or network resilience need more planning than on a small single-port recorder. The final design should match the site’s switching infrastructure, bandwidth requirements and redundancy strategy, particularly when many cameras are distributed across several network segments.
- Is the DHI-NVR5432-AI/ANZ-S2 suitable for commercial CCTV systems?
Yes. The DHI-NVR5432-AI/ANZ-S2 suits warehouses, retail sites, offices, schools, healthcare facilities and multi-building properties requiring up to 32 IP camera channels, four HDD bays and AI-assisted event review. Its 448Mbps bandwidth, dual Gigabit network ports, 8K output, extensive alarm interfaces, eSATA, iSCSI and N+M clustering provide more network, storage and integration flexibility than a smaller desktop recorder.
