Hikvision M Series · 8K · 32 Channel · 16 PoE
The Hikvision DS-7732NI-M4/16P is a 32-channel 8K Network Video Recorder built for serious Australian sites — large factories, multi-building campuses, schools, car yards, logistics centres, hotels and high-end residential estates. Sixteen built-in PoE ports power your perimeter and high-traffic cameras directly, while the remaining 16 channels accept IP cameras from your wider network — giving you up to 32 IP cameras at 32 MP each on a single, silent 1.5U chassis.
Four internal SATA bays accept up to 16 TB drives each (64 TB total), delivering months of continuous 24/7 recording even with all 32 channels running at full 4K bitrate. AcuSense-ready firmware adds deep-learning human and vehicle classification, line-crossing, intrusion detection and perimeter protection across every channel — drastically reducing nuisance alerts and turning multi-day playback searches into seconds.

Why this 32-channel NVR is built for large-site security
When 16 cameras aren't enough — and a rack-mount enterprise recorder is overkill — the DS-7732NI-M4/16P sits exactly in the middle. Sixteen onboard PoE ports remove the need for an extra PoE switch on the critical 16 cameras, and another 16 channels are free to add ANPR, panoramic, fisheye, thermal or third-party ONVIF cameras across your network. With 320 Mbps incoming bandwidth and 4 × SATA bays, this NVR is designed for projects where downtime is unacceptable and footage retention is measured in months, not days.
True 32-Channel 32 MP Input
Every channel supports cameras up to 32 MP — mix PanoVu, fisheye, ColorVu and 4K+ AcuSense cameras across a single NVR without throttling resolution or frame rate.
AcuSense Smart Detection
When paired with AcuSense cameras, the NVR runs deep-learning human and vehicle classification across all 32 channels — filtering false alarms from leaves, animals and shadows.
16 PoE Ports Built-In
Power and data over a single Cat6 run to 16 cameras, up to 100 m. IEEE 802.3 af/at compliant with 200 W total PoE budget — enough for a full perimeter without an extra switch.
Quad-SATA, 64 TB Capacity
Four internal SATA bays accept enterprise-grade surveillance HDDs up to 16 TB each, delivering month-long retention even with all 32 cameras at full 4K H.265+.
320 Mbps Incoming Bandwidth
Designed to run a full deployment of 4K ColorVu, AcuSense and PanoVu cameras simultaneously — without the bottlenecks of lower-tier NVRs.
IP Speaker Integration
Connect up to 8 Hikvision IP speakers for two-way audio warnings, scheduled announcements or live security-officer talk-down — directly from the NVR.

Engineered for Australian commercial sites
Every M Series NVR sold by CCTV Guru ships from our Australian warehouse with local stock, local firmware, and full Australian Hikvision warranty. The DS-7732NI-M4/16P operates reliably from −10 °C to 55 °C, accepts standard 100–240 V AC mains, and is purpose-built to handle the heat, humidity and dust typical of Australian commercial, industrial, and outdoor-adjacent sites.
Hik-Connect P2P
Free remote viewing on iOS and Android via the Hik-Connect app — no static IP or port forwarding required.
ONVIF Compatible
Pairs with third-party ONVIF cameras as well as the full Hikvision IP range, giving you flexibility for hybrid and multi-vendor sites.
RAID 0 / 1 / 5 / 6 / 10
Quad-SATA design supports RAID configurations for redundancy and performance — critical for sites where footage loss is not an option.
Smart Playback
Search recordings across all 32 channels by face, human, vehicle, line-crossing or intrusion event — days of footage reviewed in seconds.

Frequently asked questions
How does it handle 32 cameras with only 16 PoE ports?
Sixteen cameras connect directly to the NVR's onboard PoE ports for power + data. The remaining 16 channels accept IP cameras from your wider network — either powered by an external PoE switch or by their own power supplies.
Does the DS-7732NI-M4/16P come with hard drives?
The recorder ships as a chassis only. CCTV Guru offers pre-fitted Seagate SkyHawk or WD Purple surveillance drives from 4 TB up to 16 TB per bay — choose your configuration at checkout.
Can it be rack-mounted?
Yes — the 1.5U chassis is compatible with optional rack-mount ears for standard 19" racks. Order the rack-mount kit alongside the NVR if required.
What RAID levels are supported?
RAID 0, 1, 5, 6 and 10 are all supported across the 4 SATA bays — letting you balance storage capacity, redundancy and performance for your site.
Will it work with non-Hikvision cameras?
Yes — the NVR is ONVIF compliant and works with most third-party ONVIF IP cameras. For full AcuSense smart features you'll need genuine Hikvision AcuSense-compatible cameras.
Do you ship to my city?
We ship Australia-wide from our local warehouse — Sydney, Melbourne, Brisbane, Perth, Adelaide, Hobart, Canberra and Darwin — with most metro orders arriving in 1–3 business days.
