Hikvision DS-7732NXI-I4/16P/VPro 32-Channel VPro NVR with 16 PoE

The Hikvision DS-7732NXI-I4/16P/VPro is a 32-channel VPro Series AcuSeek NVR with 16 built-in Power-over-Ethernet ports, combining plug-and-play camera power delivery with Hikvision's Guanlan large-scale AI model analytics. It's aimed at installers who want centralised AcuSeek/AcuSearch analytics and simplified PoE camera power on a mid-sized system, without needing a separate switch for the first 16 cameras.

Hikvision DS-7732NXI-I4/16P/VPro 32-Channel VPro NVR with 16 Built-In PoE

Up to 16 IP cameras can be connected and powered directly through the recorder's built-in PoE ports, with the remaining channels (up to 32 total) addable via standard networking once the built-in ports are used. Analytics are built on Hikvision's Guanlan large-scale AI models, providing AcuSeek and AcuSearch functionality across up to 32 channels, alongside facial recognition for up to 8 channels of face picture analysis.

The recorder runs two independent AI engines, with one specifically dedicated to face picture and AcuSearch processing, letting facial recognition and broader attribute-based search run without one feature starving the other of processing capacity. Decoding capacity reaches up to 32 channels at 1080p, and video is encoded via H.265+/H.265/H.264+/H.264.

16 Built-In PoE Ports

Sixteen power-over-Ethernet ports are built directly into the recorder, letting up to 16 compatible IP cameras be powered without a separate PoE switch — useful for reducing cabling and equipment cost on installations that don't exceed 16 cameras, or as a straightforward starting point for systems that will grow later via additional network switching.

Guanlan AI Analytics: AcuSeek & AcuSearch

AcuSeek and AcuSearch analytics — covering facial recognition, perimeter protection, video structuralization and motion detection 2.0 — are available across up to 32 channels, provided connected cameras support Hikvision's AcuSense technology with AcuSearch enabled. One of the two AI engines is dedicated specifically to face picture and AcuSearch processing.

Network & Remote Access

Standard network connectivity supports Hik-Connect and DDNS for remote access setup, with smooth streaming technology and plug-in-free web access.

Frequently Asked Questions

Do I need a separate PoE switch for this NVR?

Not for the first 16 cameras — the recorder has 16 built-in PoE ports capable of powering compatible IP cameras directly. Additional channels up to the 32-channel maximum need a standard network connection, typically via a separate switch.

What is AcuSeek/AcuSearch on this model?

Hikvision's attribute-based video search and analytics capability, covering facial recognition, perimeter protection, video structuralization and motion detection 2.0, available here across up to 32 channels depending on camera compatibility.

Why does one AI engine get dedicated to face picture/AcuSearch?

Splitting the workload this way ensures facial recognition and AcuSearch processing have dedicated resources, so they aren't competing with other analytics tasks running on the second engine for the same processing budget.

How many cameras can it support in total?

Up to 32 IP camera channels, with 16 of those powerable directly via the built-in PoE ports and the remainder connected via standard networking.

Does it need compatible cameras for full analytics?

Yes, full AcuSeek/AcuSearch functionality requires connected cameras that support Hikvision's AcuSense technology with AcuSearch enabled — standard IP cameras without this support will still record but won't provide the same level of analytics.

Can it recognise faces?

Yes, facial recognition is supported across up to 8 channels of face picture analysis.

Does it support IP speakers?

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

Is this a good fit for a growing site?

Yes, since only 16 of the 32 total channels are powered via built-in PoE, there's room to expand the camera count later by adding standard network switching for the additional channels.
