16 Built-In PoE Camera Ports
The /16P version provides:
16 × Built-In PoE Network Interfaces
These allow compatible PoE cameras to connect directly to the recorder.
PoE – Power over Ethernet – allows compatible cameras to receive both network data and electrical power through a single compatible Ethernet cable.
A typical direct connection is:
IP Camera → Cat5e/Cat6 Cable → NVR PoE Port
This can significantly simplify professional CCTV installation.
Important – 32 Channels / 16 PoE Ports
The distinction between recording channels and physical PoE ports is important.
Maximum IP Camera Capacity
32 Cameras
Built-In PoE Camera Ports
16
The first sixteen compatible PoE cameras can connect directly to the NVR's built-in PoE interfaces.
To expand the system beyond sixteen cameras, additional network cameras can be connected through suitable external network infrastructure such as compatible PoE network switches.
This allows the recorder to reach its full:
32-Camera Capacity
without requiring 32 physical PoE interfaces on the NVR itself.
Up to 32MP Camera Input
The DS-7732NI-M4/16P supports camera recording resolutions up to:
32 Megapixels
Supported recording resolutions include:
- 32MP
- 24MP
- 12MP
- 8MP / 4K
- 6MP
- 5MP
- 4MP
- 3MP
- 1080p
- Lower Supported Resolutions
In Ultra-HD Resolution Mode, the NVR supports up to eight 32MP / 24MP IP video inputs.
This makes the recorder suitable for professional installations combining standard cameras with extremely high-resolution surveillance cameras.
320Mbps Incoming Bandwidth
The recorder provides:
320Mbps Incoming Bandwidth
This high bandwidth is particularly valuable in large installations using multiple high-resolution cameras.
Available bandwidth is shared across the connected IP camera streams.
System design should therefore consider:
- Number of Cameras
- Camera Resolution
- Frame Rate
- Video Bit Rate
- Audio
- Compression
- Intelligent Functions
- Recording Configuration
400Mbps Outgoing Bandwidth
The DS-7732NI-M4/16P provides:
400Mbps Outgoing Bandwidth
supporting demanding local network, remote-access and video distribution requirements.
Powerful Decoding Capability
The Hikvision M-Series platform provides powerful high-resolution decoding.
Supported configurations include up to:
- 2 × 32MP @ 30fps + 2 × 8MP @ 30fps
- 10 × 8MP @ 30fps

This is a significant advantage in professional systems requiring simultaneous display of multiple high-resolution camera streams.
True 8K HDMI Output
One of the standout features of the DS-7732NI-M4/16P is:
True 8K HDMI Video Output
HDMI 1 supports resolutions up to:
7680 × 4320 @ 30Hz
This allows connection to a compatible 8K display for extremely high-resolution local surveillance monitoring.
Unlike NVRs where very high megapixel specifications refer only to camera input, this M-Series recorder genuinely supports an 8K local HDMI display output.
Dual HDMI Outputs
The recorder provides:
2 × HDMI Outputs
HDMI 1
Supports up to:
8K – 7680 × 4320 @ 30Hz
and:

- 12MP Cameras
- 24MP Cameras
- 32MP Cameras
Dual-Stream Recording
The DS-7732NI-M4/16P supports:
Dual-Stream Recording
Different streams can therefore be used for different recording, playback and remote-access requirements.
This can improve network efficiency and remote viewing performance.
Four HDD Bays
The recorder provides:
4 × Internal SATA HDD Interfaces
This gives the DS-7732NI-M4/16P substantially greater storage capability than smaller one- or two-HDD NVRs.
Four-drive storage is particularly valuable for large installations with:
- High Camera Counts
- 8MP / 4K Cameras
- Continuous Recording
- Long Retention Requirements
- High Frame Rates
- Audio Recording
Up to 16TB Per HDD
Current Hikvision specifications support:
Up to 16TB Per HDD
With four compatible 16TB surveillance HDDs installed, the recorder can provide a potential internal raw storage capacity of:
Up to 64TB
Actual usable recording capacity and retention depend on the installed HDDs and recording configuration.
eSATA Interface
The NVR also provides:
1 × eSATA Interface
for compatible external storage applications.
This provides additional flexibility for professional surveillance storage configurations.
Storage Requirements
The appropriate HDD capacity depends on:
- Number of Cameras
- Camera Resolution
- Frame Rate
- Video Bit Rate
- H.265+ Compression
- Audio Recording
- Continuous or Event Recording
- Required Recording Retention
For professional CCTV applications, surveillance-rated HDDs are recommended.
