§ 01Overview
What the iDS-7732NXI-M4/16P/X is
The Hikvision iDS-7732NXI-M4/16P/X is a 32-channel AcuSense DeepinMind NVR with 16 built-in PoE ports, built for large sites that need AI on the recorder itself.
Using two AI engines it runs facial recognition, perimeter protection, ANPR and video structuralization across many channels, and decodes up to 8K (32MP) with 8K HDMI output.
With 320 Mbps incoming bandwidth, four HDD bays (up to 16TB each) and 16-port PoE, it powers and records up to 32 cameras from a single 1U unit.
Hard drives are not included.
§ 02Engineering
iDS-7732NXI-M4/16P/X specifications
- On-Board AI (2 Engines): Runs facial recognition, perimeter protection, ANPR and video structuralization on the NVR, so even standard cameras gain smart analytics.
- 8K Decoding & Output: Decodes up to 2 channels at 32MP (or 32 channels at 1080p) and outputs 8K via HDMI 1, with a second 4K HDMI for a separate display.
- Video Structuralization: Extracts attributes such as vehicle brand, colour and type across up to 12 channels for fast forensic search.
- 320 / 400 Mbps Bandwidth: Handles 320 Mbps incoming and 400 Mbps outgoing for smooth high-resolution recording and playback.
- 4 HDD Bays, No HDD Included: Four SATA bays support up to 16TB each (plus eSATA) so you can size storage to your retention needs.
