Product Overview
Built for enterprise-grade surveillance deployments, the iDS-9664NXI-M16/X is a 64-channel 3U rack-mount NVR powered by Hikvision’s DeepinMind deep learning platform. Designed for installation in server rooms, control centres, and communications racks, it accepts up to 64 IP cameras at resolutions reaching 32 MP, with HDMI 1 output capable of 8K display at 7680 x 4320. Equipped with 2 independent AI engines, each configurable to run a separate intelligent algorithm, it supports up to 48-channel facial recognition from face pictures, up to 24-channel perimeter protection, 12-channel video structuralization, and ANPR across all connected channels. Incorporating 16 SATA bays with RAID 0, 1, 5, 6, and 10 support, the unit also connects up to 8 IP speakers for on-site audio response. This makes it suited to large commercial campuses, transport hubs, city surveillance infrastructure, and any multi-site deployment where centralised AI analytics and long-term storage redundancy are essential.
Key Capabilities
64-Channel IP Input at Up to 32 MP
Accepts 64 simultaneous IP camera feeds at resolutions from 1080p through to 32 MP, giving large-site integrators the capacity to deploy a single recorder across an entire campus or precinct without splitting feeds across multiple units.
Dual AI Engines with Adjustable Modes
Two independent deep learning engines each run their own algorithm simultaneously. Engine mode is adjustable, letting installers allocate processing between facial recognition, perimeter protection, and video structuralization tasks to match the specific demands of each site.
Facial Recognition at Scale
Supports up to 48-channel face picture comparison at 48 pictures per second, with face picture libraries holding up to 100,000 listed faces and up to 10,000,000 captured face records. Up to 32 separate libraries accommodate multi-tenant or multi-zone access control workflows.
8K HDMI Display Output
HDMI 1 supports 8K output at 30Hz, enabling true 8K video walls or single-monitor displays without any downscaling. A second HDMI and two VGA outputs allow separate monitoring zones from the one recorder, with simultaneous HDMI/VGA pairing on each output group.
RAID Storage with 16 SATA Bays
Sixteen internal 3.5-inch SATA interfaces support up to 16 TB per drive, with RAID 0, 1, 5, 6, and 10 configurations providing storage redundancy for mission-critical recordings. An eSATA port extends capacity further to external storage arrays where site retention requirements demand it.
ANPR and AcuSearch Analytics
ANPR runs across all connected channels when using compatible cameras, capturing plate number, colour, and type alongside vehicle brand, colour, and type. AcuSearch processes up to 691,200 targets per day by NVR, enabling rapid post-event forensic retrieval across the full 64-channel camera network.
Best For
- Enterprise Campus Surveillance: The 64-channel input and dual AI engines handle the volume and analytical complexity of large corporate, government, or educational campus deployments from a single rack-mounted unit.
- Transport and Logistics Hubs: ANPR across all channels and vehicle attribute capture make this recorder well matched to entry/exit monitoring at ports, freight yards, and bus or rail interchanges where vehicle identification is operationally critical.
- High-Security Access Zones: With up to 32 face picture libraries and 100,000 listed faces per library, the iDS-9664NXI-M16/X supports multi-zone watchlist management for facilities requiring identity verification at multiple controlled access points.
- Control Room Installations: Dual HDMI and dual VGA outputs with 8K capability on the primary output allow operators to run multiple independent display zones, including a dedicated 8K video wall feed, from a single rackmount unit.
- Long-Retention Recording Sites: RAID 5 and RAID 6 support across 16 bays means integrators can configure meaningful storage redundancy while maintaining high total raw capacity, suited to sites with 30-day or greater retention mandates.
Why Choose the iDS-9664NXI-M16/X
What separates the iDS-9664NXI-M16/X from a standard high-channel NVR is the on-board DeepinMind processing. Where a conventional 64-channel recorder simply stores and displays footage, this unit actively analyses it across facial recognition, perimeter intrusion detection, video structuralization, and ANPR concurrently. The dual-engine architecture means those analytical tasks do not compete for a single resource pool, giving integrators the ability to dedicate one engine entirely to facial comparison at 48 pictures per second while the second handles perimeter events across up to 24 cameras. The 8K HDMI output and 16-bay RAID storage put it in a category that suits purpose-built control rooms rather than small business headends. Available at Security Wholesalers, the iDS-9664NXI-M16/X is a purpose-engineered solution for integrators who need AI at the recorder level without relying solely on camera-side processing.
Buyer Decision Tips
Storage Planning: The iDS-9664NXI-M16/X ships without hard drives. With 16 SATA bays supporting up to 16 TB each, total raw capacity can reach 256 TB. Before specifying drives, calculate your retention requirement based on channel count, resolution, frame rate, and compression format. H.265+ significantly reduces storage consumption compared to H.264, which is important at 64 channels. Choose a RAID level that balances redundancy with usable capacity for your site’s retention mandate.
AI Feature Dependencies: Some AI functions on the iDS-9664NXI-M16/X are processed by the NVR itself and work with any connected IP camera. Others, including ANPR, AcuSearch by camera, and perimeter protection powered by Large Model, require compatible Hikvision AcuSense cameras. Confirm your camera specifications before configuring AI-by-camera features, particularly if you are integrating third-party ONVIF cameras into the system.

Ideal Use Cases
City and Public Space Surveillance
With 64-channel input and AcuSearch processing up to 691,200 targets per day, the iDS-9664NXI-M16/X supports large-footprint public area deployments where operators need fast forensic retrieval across dozens of simultaneous feeds.
Airport and Transport Terminals
ANPR across all camera channels, combined with facial recognition at 48-channel throughput, makes this recorder suited to transport infrastructure where both vehicle and passenger identity verification are required in a single system.
Corporate Headquarters and Campuses
Up to 32 face picture libraries with 100,000 entries each allow multi-building campuses to maintain separate watchlists per zone or building, with the dual AI engines handling concurrent analytics across entrances, car parks, and internal corridors.
Control Room Monitoring Suites
The 8K HDMI 1 output combined with a second independent HDMI and two VGA outputs lets control room designers configure multi-zone display walls with different feed layouts simultaneously from the one recorder without requiring a separate video controller.
High-Security Government Facilities
Perimeter protection across up to 24 channels, combined with 16-alarm input wiring and RAID-redundant storage, supports facilities where both real-time intrusion alerting and guaranteed footage retention are non-negotiable operational requirements.
Large Retail or Casino Environments
Video structuralization across 12 channels identifies and classifies people and objects within the scene, supporting loss prevention workflows that require searchable metadata rather than manual footage review across a high-camera-count floor.
Choosing the Right Model
- Choose this model if: Your deployment requires 64 IP camera channels with on-board deep learning analytics, including facial recognition at scale, perimeter protection, video structuralization, and ANPR, within a single 3U rack-mount unit that also supports 8K display output and RAID-protected storage across 16 drives.
- Choose a different model if: Your site requires 32 channels or fewer and does not need on-board DeepinMind AI processing. A standard high-channel NVR without dual AI engines will deliver lower cost per channel for deployments where analytics are handled entirely at the camera level or are not required at all.
- Choose a different model if: Your installation environment cannot accommodate a 3U rack chassis or does not have a controlled equipment room. The iDS-9664NXI-M16/X is a rack-mount unit designed for server room deployment and is not suited to under-desk or wall-bracket installations.
FAQs
- Does the iDS-9664NXI-M16/X perform facial recognition using any connected camera?
Facial recognition from a live video stream is supported on up to 16 channels at 2 MP (8-ch per engine, up to 8 MP). Face picture comparison from captured images runs across up to 48 channels. For stream-based recognition, camera resolution and AI-by-NVR processing limits apply. AI-by-camera facial recognition is available across all channels when using compatible Hikvision cameras that support the feature.
- How many hard drives does this NVR support and what is the maximum storage capacity?
The iDS-9664NXI-M16/X has 16 internal 3.5-inch SATA interfaces, each supporting up to 16 TB, giving a theoretical raw capacity of 256 TB. An additional eSATA port allows connection to external storage arrays. Hard drives are not included and must be purchased separately. Surveillance-grade drives from WD Purple or Seagate SkyHawk are recommended.
- What RAID modes are available and which should I use for a mission-critical site?
RAID 0, 1, 5, 6, and 10 are all supported. RAID 5 offers a balance of usable capacity and single-drive redundancy across multiple drives. RAID 6 tolerates 2 simultaneous drive failures and is suited to high-criticality recordings where any footage loss is unacceptable. RAID 0 is not recommended for live surveillance as it provides no redundancy.
- Can I connect third-party ONVIF cameras to this NVR and still use the AI features?
ONVIF (Version 2.5) and RTSP camera connections are supported for basic recording and live view. However, AI-by-camera features such as ANPR, AcuSearch via camera, and Large Model-powered perimeter protection require compatible Hikvision AcuSense cameras. AI-by-NVR analytics such as facial recognition from captured pictures and perimeter protection without Large Model work independently of camera brand.
- What does the dual AI engine architecture mean in practical terms for an installer?
Each of the 2 engines operates independently and can run a different algorithm. For example, one engine can be dedicated to facial recognition processing across a set of entrance cameras while the second handles perimeter protection across outdoor perimeter cameras. Engine mode is adjustable through the NVR interface, allowing the allocation to be changed as site requirements evolve.
- What display outputs does the iDS-9664NXI-M16/X support for a multi-monitor control room?
The unit provides HDMI 1 (up to 8K at 30Hz), HDMI 2 (up to 4K at 60Hz), 2 x VGA (both at 1080p/60Hz), and 1 CVBS output. HDMI 1 and VGA 1 output simultaneously, as do HDMI 2 and VGA 2. When HDMI 1 is set to 8K, HDMI 2 is limited to 1080p. This allows operators to run an 8K overview wall alongside a separate 1080p operational display from the one recorder.
- How does AcuSearch work on this NVR and what is the daily processing limit?
AcuSearch enables attribute-based forensic search across recorded footage, identifying targets by characteristics rather than requiring manual timeline scrubbing. When processed by the NVR, up to 8 channels are supported at up to 691,200 targets per day. When AcuSearch-capable cameras handle processing themselves and push structured data to the NVR, all connected channels contribute and the same 691,200-target daily limit applies per channel. Available through Security Wholesalers, this unit is one of the few NVRs in the Hikvision range that supports both NVR-side and camera-side AcuSearch simultaneously.
- Is the iDS-9664NXI-M16/X suitable for rack mounting and what are the physical dimensions?
Yes, the iDS-9664NXI-M16/X is a 3U rackmount unit measuring 442 x 494 x 150 mm (W x D x H) and weighing up to 13 kg without drives installed. It requires a standard 19-inch equipment rack with at least 530 mm of usable depth to accommodate both the chassis and rear cable connections. Ensure adequate rack airflow and power circuit planning given the consumption of up to 50 W without drives, with additional draw once multiple surveillance HDDs are installed.
