Hikvision DS-7732NXI-I4/16P/S(E) 32-Channel AcuSense NVR with 16 PoE

The Hikvision DS-7732NXI-I4/16P/S(E) is a 32-channel AcuSense Series NVR with 16 built-in Power-over-Ethernet ports, representing an earlier NVR generation than the newer VPro-branded models in Hikvision's range. Hikvision's own product page lists this model as discontinued, though a current datasheet is still published, so we'd recommend confirming stock availability with your supplier before committing to an order.

Hikvision DS-7732NXI-I4/16P/S(E) 32-Channel AcuSense NVR with 16 Built-In PoE

Unlike the newer Guanlan-powered VPro series, this AcuSense-generation recorder uses Hikvision's earlier deep-learning algorithm for its analytics, with perimeter protection supported across up to 4 channels and facial recognition available for up to 4 channels of video stream analysis or 8 channels of face picture analysis. It supports up to 32 IP camera channels overall, with decoding capacity of up to 16 channels at 1080p, meaningfully lower than the newer VPro-generation models covering the same channel count.

Two self-adaptive 10/100/1000 Mbps Ethernet interfaces provide network connectivity, with Hik-Connect and DDNS support for remote access, and smooth streaming technology with plug-in-free web access carried over from Hikvision's broader NVR platform.

16 Built-In PoE Ports

Sixteen power-over-Ethernet ports are built into the recorder, allowing up to 16 compatible IP cameras to be powered directly without a separate switch, with the remaining channels up to the 32-channel maximum requiring standard networking.

AcuSense-Generation Analytics

Perimeter protection and facial recognition are supported, but at a smaller scale than the newer VPro-series models — up to 4 channels of perimeter protection and up to 4 channels of facial recognition video stream analysis (or 8 channels of face picture analysis), reflecting this recorder's positioning as an earlier, more budget-oriented generation.

Product Lifecycle Note

This exact model is listed as discontinued on Hikvision's global product page, though a datasheet remains published in some regional markets. If ongoing supply matters for your project, it's worth checking current availability before relying on this specific SKU for future stock.

KEY BENEFITS

• Lower cost positioning than the newer VPro-series equivalents

KEY FEATURES

• 32-channel IP camera input (16 via built-in PoE)
• 16 built-in Power-over-Ethernet ports
• H.265+ / H.265 / H.264+ / H.264 video compression
• Perimeter protection up to 4 channels
• Facial recognition up to 4-ch video stream / 8-ch face picture
• Up to 16-ch@1080p decoding capability
• 2 × self-adaptive 10/100/1000 Mbps Ethernet interfaces
• Hik-Connect & DDNS support
• Up to 8-ch IP speaker connections

IDEAL FOR

• Sites standardising on Hikvision's earlier AcuSense-generation NVR platform
• Budget-conscious 32-channel installs wanting basic facial recognition/perimeter analytics
• Installations wanting 16 built-in PoE ports without needing full VPro-generation analytics
• Extending an existing AcuSense-series estate with a matching recorder generation
• Sites where lower decoding capacity (16-ch@1080p) is sufficient for the camera mix
• Installers price-sensitive to newer VPro/DeepinMind model premiums
• Facilities needing basic Hik-Connect remote access without advanced AI features
• Sites for which supply continuity should be confirmed given discontinued status

Frequently Asked Questions

Is this model still available to order?

Hikvision's global product page lists it as discontinued, though a datasheet remains published in some regional markets — we'd strongly recommend confirming current stock availability with your supplier before committing to an order, especially for larger quantities.

How does this compare to the VPro-series equivalent (DS-7732NXI-I4/16P/VPro)?

This AcuSense-generation model uses an earlier deep-learning platform with more limited analytics (4-channel perimeter protection, 4-channel facial recognition video stream) and lower decoding capacity (16-ch@1080p), compared to the VPro model's Guanlan-based AcuSeek/AcuSearch analytics across up to 32 channels and higher decoding capacity.

How many cameras can it power directly?

Up to 16 compatible IP cameras via the built-in PoE ports, with the remaining channels up to the 32-channel maximum connectable via standard networking.

Does it support facial recognition?

Yes, but at a smaller scale than newer models — up to 4 channels of video stream facial recognition, or up to 8 channels of face picture analysis.

Does it support perimeter protection?

Yes, across up to 4 channels, using Hikvision's deep-learning algorithm from this NVR generation.

What is the decoding capacity?

Up to 16 channels at 1080p, which is lower than comparable newer VPro-generation NVRs covering the same 32-channel input count.

Can I access it remotely?

Yes, via Hik-Connect and DDNS support.

Does it support IP speakers?

Yes, up to 8 channels of IP speakers can be connected for audible alerts.
