Hikvision iDS-7732NXI-M4/16P/X - 32 Channel 16 PoE DeepinMind 8K NVR

The Hikvision iDS-7732NXI-M4/16P/X is a 32-channel DeepinMind network video recorder with sixteen built-in PoE ports, two AI engines, four SATA bays and 8K output.

What DeepinMind adds over AcuSense and VPro

• AcuSearch: 691,200 targets a day — against 300,000 on the VPro and 172,800 on the I-series
• Face capture library: 5,000,000 pictures, plus 100,000 in the watch list and 10,000 in the stranger library
• Face comparison across 32 channels at 48 pictures per second — double the channel coverage of the 16-channel DeepinMind models
• Video structuralisation — the recorder categorises what it sees rather than simply detecting it
• Large Model support for perimeter protection on every channel

The bandwidth here is better than its 16-channel siblings

320 Mbps incoming and 400 Mbps outgoing — and unusually for this range, the outgoing figure is the higher of the two. That matters on a large site: it is the outgoing number that limits you when several people review footage remotely while thirty-two cameras keep recording. Several recorders in this catalogue have the opposite arrangement, and it catches people out.

The PoE covers half the channels

Thirty-two channels, sixteen PoE ports at 200 W. Cameras 1 to 16 plug straight into the recorder; channels 17 to 32 need a switch. Fine for a phased installation, but budget for switches if all thirty-two need powering centrally.

Be realistic about whether you need DeepinMind

Most sites do not. If you want fewer false alarms and quick searching, the DS-7732NXI-I4/16P/S or a VPro model does that for a fraction of the price. DeepinMind earns its cost where watch-list face matching or structured search across millions of captures is an operational requirement — and where somebody will actually administer the libraries.

What you'll need with it

• Cameras that suit the analytics. Face recognition depends on camera position, angle and pixel density on the face far more than on megapixels. Worth planning properly — talk to us before ordering.
• A PoE switch for channels 17–32 if you are running all thirty-two.
• Hard drives — none are supplied. Four 3.5-inch bays at up to 16 TB. Size them with our CCTV storage calculator.

Frequently asked questions

How is it different from the iDS-7716NXI-M4/16P/X?

Double the channels (32 against 16), more bandwidth (320/400 against 256/256) and face comparison across 32 channels rather than 16. Same AI engines, same storage, same chassis.

Can I power all 32 cameras from it?

No — sixteen PoE ports at 200 W. Cameras 17 to 32 need a switch.

Is DeepinMind worth it over VPro?

Only if you need watch-list face matching, structured search across large volumes, or analytics on many channels at once.

Does it come with hard drives?

No. Four 3.5-inch SATA drives up to 16 TB each, supplied separately.
