DS-7732NI-M4/16P

Manufacturer reference

Manufacturer details describe the cited version. Confirm the exact unit and intended system.

Video and audio

Device class

M Series 8K NVR

IP video inputs

32 channels; camera-input count is not the PoE-port or remote-connection count.

Maximum input resolution

Up to 32 MP; high-resolution channel and bandwidth restrictions apply.

High-resolution input limit

At most 8 inputs at 32 MP / 24 MP; Ultra-HD mode must be activated for these inputs.

Incoming bandwidth

320 Mbps

Outgoing bandwidth

400 Mbps; not the incoming-bandwidth limit.

HDMI 1 output

7680 × 4320 at 30 Hz; 3840 × 2160 at 60/30 Hz; 2560 × 1440 or 1920 × 1080 at 60 Hz.

HDMI 2 output

3840 × 2160 at 60/30 Hz; 2560 × 1440 or 1920 × 1080 at 60 Hz. When HDMI 1 outputs 8K, HDMI 2 is limited to 1080p.

VGA output

1920 × 1080 at 60 Hz

Video output mode

HDMI1/VGA simultaneous output; HDMI2/VGA independent output.

CVBS output

1 BNC output, 1.0 Vp-p, 75 Ω; PAL 704 × 576 or NTSC 704 × 480. This is not an analog camera input.

Audio output

1 RCA channel, linear; the printed impedance shorthand requires separate confirmation.

Two-way audio input

1 RCA channel, 2.0 Vp-p, 1 kΩ, using the audio input.

Video decoding formats

H.265+, H.265, H.264+ and H.264

Recording resolutions

32 MP, 24 MP, 12 MP, 8 MP, 6 MP, 5 MP, 4 MP, 3 MP, 1080p, UXGA, 720p, VGA, 4CIF, DCIF, 2CIF, CIF or QCIF; the high-resolution input limit still applies.

Synchronous playback

16 channels; this does not increase camera-input or high-resolution decoding capacity.

Dual-stream recording

Supported in the document; recording and decoder limits still apply.

Stream types

Video, or Video & Audio

Audio compression

G.711 μ-law, G.711 A-law, G.722, G.726, AAC and MP2L2

Network, storage and interfaces

Remote connection reference

128 remote connections; not additional IP camera inputs.

LAN interface

1 RJ45 10/100/1000 Mbps self-adaptive Ethernet interface; separate from camera PoE ports.

PoE ports

16 RJ45 10/100 Mbps self-adaptive camera interfaces; Fast Ethernet camera connections.

PoE power reference

At most 200 W total PoE power reference; not 200 W per port.

PoE standard

IEEE 802.3af/at; confirm camera and cable requirements.

Internal disk interfaces

4 SATA interfaces; HDDs require separate confirmation.

Disk capacity reference

Up to 16 TB per HDD in this document; not an included disk set or configured usable capacity.

External disk interface

1 eSATA interface; external equipment and configuration require confirmation.

Serial interfaces

2 half-duplex RS-485 interfaces and 1 RS-232 interface

Alarm I/O reference

16 inputs / 9 outputs; output count is not a relay load rating.

USB interfaces

Front: 1 × USB 2.0; Rear: 1 × USB 3.0

Ctrl 12V output

12 V DC, 1 A; triggered through alarm output 9, not an independently assumed relay power rating.

DC 12V output

12 V DC, 1 A reference; not a combined 2 A budget with the controlled output.

Power, environment and chassis

AC power input

100–240 V AC, 50–60 Hz; check supplied plug and electrical requirements.

Consumption excluding HDD and PoE

At most 15 W, without HDD and with PoE off.

Working temperature

−10–55 °C

Working humidity

10–90%

Chassis reference

19-inch rack-mounted chassis, 1.5U; mounting hardware and installed clearances require confirmation.

Weight excluding HDD

At most 5 kg, excluding HDD; not shipping or populated-system weight.

Camera and integration selection

Camera-event and POS references

VCA events, camera features and POS information overlay are listed. Confirm the exact camera/POS devices, firmware and event configuration.

IP-speaker reference

Up to 8 IP speaker channels in this document; exact speakers, protocols, firmware and concurrent operation require confirmation.

Selection notes

• DS-7732NI-M4/16P exact full-model reference only; confirm the actual supplied label, firmware and document applicability.
• Input count, incoming/outgoing bandwidth, decoding, synchronous playback and display modes are separate limits; do not assume all maxima operate together.
• PoE figures are total output references, not per-port guarantees or populated-system consumption; check the complete camera load, cabling and power budget.
• The controlled 12 V output is triggered through alarm output 9; verify exact wiring and loads. No combined DC-output current budget or relay contact rating is established.
• Consumption and weight exclude HDDs; the consumption figure also requires PoE off. These values are not a fully populated operating system or shipping weight.
• Camera-event, POS and integration functions depend on the exact compatible devices, firmware and configuration; no recorder-native AI, interoperability or included licence is assumed.
• Decoder modes, where stated, are separate and not summed; 40 decoded 1080p streams do not create 40 IP camera inputs.
• No disk compatibility, package contents, installed clearance, local stock, price, delivery or warranty has been confirmed.
