§ 01Overview
What the DS-7732NI-M4/24P is
The Hikvision DS-7732NI-M4/24P is a 32-channel 8K network video recorder with 24 PoE ports built in, aimed at medium to large Australian commercial sites.
Those 24 PoE ports (802.3 af/at, up to 210W total) power and connect cameras over a single cable, while the recorder accepts up to 32 channels in total and resolutions up to 32MP.
H.265+ compression reduces bandwidth and disk use, and HDMI 1 outputs 8K for detailed viewing.
Storage runs across four SATA bays (up to 16TB each, 64TB total) and a 4TB surveillance drive is supplied so you can record straight away.
To connect more than 24 cameras, add a separate PoE switch for the extra channels.
§ 02Engineering
DS-7732NI-M4/24P specifications
- Records up to 32 IP channels at resolutions up to 32MP for sharp faces and licence plates.
- Four SATA bays accept up to 16TB per drive (64TB total), and a 4TB surveillance drive is included.
- 320 Mbps incoming and 400 Mbps outgoing bandwidth for smooth concurrent recording and remote viewing.
- Dual HDMI plus VGA outputs, with 8K (7680 x 4320) available on HDMI 1.
- H.265+ compression lowers bandwidth and storage needs on a 1.5U rack chassis running on 100-240 VAC.

§ 04Why choose this
Built for the way you actually use the DS-7732NI-M4/24P
Records straight away
A 4TB surveillance drive is included, so the recorder is ready to store footage out of the box, with three more bays for expansion up to 64TB.
True 8K detail
H.265+ keeps file sizes down while HDMI 1 outputs 8K, letting one screen show a detailed multi-camera layout.
Headroom to 32MP
Standard channels record everyday cameras, while select inputs support up to 32MP for areas where the finest detail matters.
§ 05Where it fits
Right at home in these scenarios
Retail and hospitality
Cover tills, floors, stockrooms and entries with up to 32 cameras and direct PoE wiring.
Medium commercial sites
Offices, clinics and warehouses that need a higher channel count than an 8 or 16-channel NVR can give.
Multi-tenant buildings
Record shared lobbies, car parks and corridors with most cameras powered straight from the recorder.
Sites planning growth
Start with the 24 PoE ports, then expand to 32 channels via an added switch as the site grows.
§ 06Setup
Installation & setup
In the box
DS-7732NI-M4/24P recorder with a 4TB drive fitted, power cable, mouse and rack-mount hardware.
Connecting cameras
Plug up to 24 cameras into the built-in PoE ports for power and data. For channels 25-32, run those cameras through a separate PoE switch into the network port.
PoE budget
The 24 ports share up to 210W. Add up your cameras' power draw and use an external switch for any high-wattage models if you approach the budget.
Storage and power
Add surveillance-rated drives in the spare bays (up to 16TB each), then mount in a 1.5U rack space and connect to 100-240 VAC.
