The Hikvision iDS-7732NXI-M4/16P/X is a 32-channel DeepinMind M Series NVR with 16 built-in Power-over-Ethernet ports, aimed at installers who want plug-and-play camera power delivery alongside centralised deep-learning analytics, without needing a separate PoE switch for at least the first 16 cameras on the system.
Hikvision iDS-7732NXI-M4/16P/X 32-Channel DeepinMind NVR with 16 Built-In PoE Ports
Having 16 PoE ports built directly into the recorder simplifies installation considerably on small-to-mid sites: up to 16 compatible IP cameras can be connected and powered directly from the NVR itself, with no separate PoE switch or injectors required for those channels. The remaining channels (up to 32 total) can still be added via a standard network connection through additional switching infrastructure, giving installers headroom to grow the system beyond the built-in PoE port count.
Like other DeepinMind M-series recorders, it runs centralised deep-learning analytics with adjustable dual-engine processing, supporting facial recognition, perimeter protection and video structuralization directly on the recorder. Decoding capacity is tiered by resolution, from 2 channels at 32MP down to 32 channels at 1080p, so a mixed-resolution camera estate can be accommodated on a single system.
16 Built-In PoE Ports
The recorder includes 16 power-over-Ethernet ports, allowing up to 16 compatible IP cameras to be connected and powered without a separate PoE switch — useful for reducing both cabling and equipment cost on installations where the camera count doesn't exceed the built-in port count, or as a simpler starting point on larger systems that will later be expanded via a switch.
Dual-Engine Deep-Learning Analytics
Two independent AI engines can each be configured to run a different intelligent algorithm, supporting facial recognition (up to 16 face libraries, up to 100,000 list-library pictures, 10,000 stranger-library pictures, and up to 5,000,000 in face capture storage), perimeter protection up to 24 channels, and video structuralization up to 12 channels.
Facial Recognition
Face picture comparison from live camera streams is supported across up to 32 channels combined (24 channels per engine), with a comparison speed of up to 48 pictures per second, enabling both list-based alarms for recognised individuals and stranger alarms for unrecognised faces.
Network & Remote Access
A single self-adaptive 10M/100M/1000M Ethernet interface provides uplink connectivity, with Hik-Connect and DDNS support simplifying remote access setup, and web access available without needing a browser plug-in.

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. If you need to connect more than 16 cameras (up to the 32-channel maximum), the additional channels will need a standard network connection, typically via a separate switch.
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.
How does the facial recognition compare to the larger DeepinMind models?
It supports up to 16 face picture libraries and up to 5,000,000 face captures, which is a somewhat smaller capacity than the 32-channel and 64-channel DeepinMind models in the range, reflecting this unit's positioning for smaller sites.
Can it run two different analytics types at once?
Yes, it has two independent AI engines that can each run a different intelligent algorithm, so for example facial recognition and perimeter protection can run simultaneously across different channel groups.
What is perimeter protection used for here?
It uses deep-learning analytics to detect intrusion into a defined area while filtering out common false triggers like moving foliage or shadows, and is supported across up to 24 channels on this model.
Does it support IP speakers?
Yes, up to 8 channels of IP speakers can be connected for audible alerts triggered by detected events.
How is remote access set up?
Through Hik-Connect and DDNS support, which simplify remote viewing configuration, along with web access that doesn't require a browser plug-in.
Is this a good fit for a site that might grow later?
Yes, since the recorder supports up to 32 channels total while only 16 are powered directly via built-in PoE, there's room to expand the camera count later by adding standard network switching for the additional channels.
