Description
Hikvision DS-7732NI-M4/16P 32 Channel 16 PoE 8K NVR
Hikvision DS-7732NI-M4/16P brings up to 32 IP cameras together for central recording, live viewing and playback. This Hikvision 32 channel NVR includes 16 built-in PoE ports, 320Mbps incoming bandwidth and four SATA hard-drive bays, making it suitable for larger business and commercial CCTV installations.
Support for cameras up to 32MP, HDMI output up to 8K and Hik-Connect remote access gives you flexibility when building or upgrading your system. Select the hard-drive option you need from the dropdown, or choose No HDD if you are supplying compatible storage separately.
Why Choose This Product?
Choose this Hikvision 8K NVR when you need room for more cameras, high-resolution recording and multiple storage drives. The combination of built-in PoE connections and network camera access allows you to plan a system around the layout of your premises.
The Hikvision DS-7732NI-M4/16P also supports events from compatible smart cameras, local monitor viewing and remote access. Camera channel capacity, available PoE power, recording bandwidth and decoding performance are separate limits, so the configuration can be matched to your actual installation.
32 Camera Channels and 16 PoE Ports
This 16 PoE NVR supplies power and data to compatible cameras through its built-in IEEE 802.3af/at ports. The recorder has a shared PoE power budget of 200W, so camera quantities must be planned around their maximum power requirements and cable losses.
Up to 32 IP cameras can be connected in total. Cameras beyond the 16 built-in ports connect over the network using suitable external switching and power equipment. Keep the combined incoming streams within the recorder’s 320Mbps bandwidth limit.
High-Resolution Recording and Playback
The Hikvision DS-7732NI-M4/16P supports camera resolutions up to 32MP. Inputs at 16MP, 24MP or 32MP are limited to eight channels; resolutions below 16MP, including 12MP, can be used across all 32 channels within the recorder’s bandwidth limits.
Recording capacity and simultaneous display performance are different. The specified decoding capability includes six 12MP streams or ten 8MP streams at 30fps. Up to 16-channel synchronous playback is supported, with the usable resolution and frame rate subject to decoding capacity and display settings.
8K HDMI and Flexible Monitor Connections
This Hikvision 8K NVR provides two HDMI connections, a VGA output and a CVBS output. HDMI 1 supports up to 7680 × 4320 at 30Hz, while HDMI 2 supports up to 3840 × 2160 at 60Hz in supported configurations.
When HDMI 1 is set to 8K, HDMI 2 is limited to 1080p. Dual 4K HDMI output is supported as an alternative. Use a display and cable that support the selected resolution; an ordinary Full HD monitor displays at its own supported resolution.
Four Hard-Drive Bays and Flexible Storage
Four SATA interfaces support compatible hard drives up to 16TB each, giving a maximum internal capacity of 64TB when all four bays are populated with supported drives. One eSATA interface provides an additional storage connection. RAID is not supported.
H.265+ compression and dual-stream recording help manage storage and bandwidth. Recording duration depends on camera quantity, resolution, bit rate, activity and recording schedules. The No HDD option requires a suitable drive to be fitted before local recording and playback are available.
Smart Camera Events and Remote Access
The recorder supports VCA events from compatible cameras, including motion, line crossing and intrusion. Functions such as ANPR, heat maps and people counting depend on suitable cameras and system configuration. POS information can be overlaid on live view and playback, with supported POS-triggered recording and alarms.
Use Hik-Connect for remote access once the recorder and network are configured. Off-site viewing requires internet connectivity. The Hikvision DS-7732NI-M4/16P also provides alarm connections and supports up to eight compatible IP speakers for suitable system integrations.

Ideal For
This Hikvision 32 channel NVR suits shops, offices, warehouses, schools, workshops and larger commercial premises needing central recording from multiple IP cameras, flexible storage and local or remote viewing.
Installation & Compatibility
Install this 16 PoE NVR indoors in a ventilated location. Connect cameras directly to the built-in ports or through suitable network switches, and select recording settings within the channel, bandwidth and decoding limits.
12MP camera power planning: The linked DS-2CD33C7G3-LISUY/SL camera requires up to 18W through PoE+. Sixteen cameras at that maximum would require 288W before cable losses, exceeding the NVR’s 200W budget. Use suitably rated external PoE+ equipment or separate camera power for configurations that exceed the recorder’s power capacity.
Choose surveillance hard drives and allow sufficient capacity for your recording schedule. Camera analytics, audio and event functions depend on compatible equipment, firmware and settings. Select a monitor resolution supported by both the recorder and display.
Complete Your Installation
Add the Hikvision DS-2CD33C7G3-LISUY/SL 12MP IP camera, a 20m outdoor CAT5 network cable and a CCTV monitor to build your system. The DS-1280ZJ-DM21 junction box is available for compatible camera installations. All accessories are sold separately.
Junction box compatibility: Confirm the correct box for your camera before ordering. The linked 12MP camera’s current datasheet specifies DS-1280ZJ-PT6-Y, so DS-1280ZJ-DM21 compatibility should be confirmed separately.
