Product Overview
Large enterprise and institutional surveillance deployments demand more from a recorder than simple storage, and the Hikvision iDS-9664NXI-M8/X DeepinMind NVR is engineered to meet that demand head-on. Supporting up to 64 IP cameras and equipped with 8 SATA interfaces, this 64-channel NVR brings server-side deep learning analytics to facilities where camera-side AI alone is not enough. Dual AI engines handle facial recognition across up to 16 channels for live video streams or up to 48 channels for face picture comparison, while perimeter protection runs across up to 24 channels without relying on AcuSense cameras. AcuSearch enables rapid metadata-driven retrieval across all connected channels. H.265+ compression reduces storage demand across the 8-bay configuration, and 4K HDMI output supports high-resolution monitoring stations. Compatible with Hik-Connect and iVMS-4200 for centralised remote management, the iDS-9664NXI-M8/X suits airports, hospital campuses, university precincts, and large retail complexes where AI-powered oversight at scale is a core operational requirement. Note: this is a special order item with approximately 6-8 weeks lead time. HDD not included.
Key Capabilities
Dual Deep Learning AI Engines
Two independent AI engines allow the iDS-9664NXI-M8/X to run multiple intelligent algorithms simultaneously. Each engine can be configured independently, enabling facial recognition and perimeter protection to operate in parallel across large channel counts without performance compromise.
64-Channel IP Camera Input
Connect up to 64 IP cameras at resolutions reaching 12 MP per channel, with decoding capacity including 4-ch at 12 MP, 8-ch at 8 MP, 16-ch at 4 MP, and 32-ch at 1080p. This makes the NVR suited to sprawling facilities that require comprehensive coverage from a single recording platform.
Facial Recognition at Scale
NVR-side facial recognition processes up to 16 channels for live stream analysis or up to 48 channels for face picture comparison. Face picture libraries support up to 32 separate libraries and up to 100,000 entries in a list library, making it practical for access monitoring across large employee or visitor populations.
8-Bay SATA Storage with RAID
Eight SATA interfaces support up to 10 TB per drive, delivering substantial raw storage capacity. RAID modes 0, 1, 5, 6, and 10 are supported, allowing administrators to balance storage redundancy against capacity based on the criticality of the recorded footage.
AcuSearch Metadata Retrieval
AcuSearch enables structured searches across recorded footage using AI-tagged metadata. By NVR processing, up to 8 channels and up to 691,200 targets per day can be indexed. When camera-side AcuSearch is enabled, all connected channels contribute to the searchable dataset, dramatically reducing manual review time.
H.265+ Compression and 4K Output
H.265+ encoding reduces bandwidth and storage consumption compared to H.264 while maintaining video quality across high-resolution channels. Dual HDMI and VGA outputs support 4K monitoring stations, giving operators a high-resolution live view suited to command centre or security control room environments.
Best For
- Enterprise and Institutional Sites: The 64-channel input and dual AI engine architecture make this NVR suited to airports, hospitals, university campuses, and council facilities that require centralised recording and analytics across a large number of camera positions.
- Facial Recognition Deployments: With support for up to 32 face picture libraries and up to 100,000 entries, this recorder is appropriate for sites that need to monitor known individuals across entry points, staff access zones, or high-traffic public areas.
- Sites with Mixed Camera Intelligence: The NVR-side AI engines can perform perimeter protection, facial recognition, and video structuralization independently, so the system delivers deep learning analytics even when connected cameras do not have built-in AcuSense or AI capabilities.
- High-Retention Recording Environments: The 8-bay configuration with RAID support is suited to applications where continuous multi-week or multi-month retention is required across dozens of high-resolution camera feeds.
- Security Control Rooms: Dual HDMI and VGA outputs at 4K resolution support multi-monitor operator stations, making this recorder appropriate for staffed security control rooms where multiple live views and playback sessions run simultaneously.
Why Choose the iDS-9664NXI-M8/X
The iDS-9664NXI-M8/X occupies a distinct position in the Hikvision NVR range by combining 64-channel capacity with on-board deep learning through 2 dedicated AI engines. A standard NVR without DeepinMind processing would depend entirely on camera-side intelligence to deliver analytics. This model runs facial recognition, perimeter protection, video structuralization, and AcuSearch at the recorder level, which means organisations can deploy a mix of camera types and still benefit from consistent AI-driven event detection and footage retrieval across all 64 channels. The 8-bay SATA configuration with RAID 0, 1, 5, 6, and 10 support adds a layer of storage resilience that lower-tier recorders do not provide. For security integrators and end users planning large-scale surveillance infrastructure, the iDS-9664NXI-M8/X is available through Security Wholesalers as a special order item. Please note approximately 6-8 weeks lead time should be factored into project planning.
Buyer Decision Tips
Storage Planning: The iDS-9664NXI-M8/X ships without HDDs. With 8 SATA bays each supporting up to 10 TB, the maximum raw capacity is 80 TB. Before ordering, calculate your required retention period based on channel count, resolution, and recording mode. For critical deployments, factor in a RAID configuration that provides redundancy, such as RAID 5 or RAID 6, which will reduce your usable capacity below the raw total. Surveillance-grade drives from WD Purple or Seagate SkyHawk series are recommended for continuous 24/7 write workloads.
AI Engine Allocation: The dual AI engines on this NVR can each run one intelligent algorithm at a time, and the engine mode is adjustable. If you need both facial recognition and perimeter protection running simultaneously across your channel count, plan your engine allocation before deployment. NVR-side perimeter protection supports up to 24-ch at 2 MP without the Large Model, while facial detection and analytics supports up to 16-ch at 2 MP per engine. If your site requires AI across more channels than the NVR engines can handle, pair this recorder with AcuSense or AI-capable cameras that perform analytics at the camera level and pass results to the NVR.

Choosing the Right Model
- Choose this model if: Your project requires 64 IP camera channels with NVR-side deep learning analytics, including facial recognition, perimeter protection, and AcuSearch, and your site has a need for high-capacity redundant storage across 8 SATA bays. This recorder is appropriate when the deployment cannot rely solely on camera-side AI to deliver analytics at scale.
- Choose a different model if: Your channel count is 32 or fewer and NVR-side AI at this level of scale is not required – a lower-channel DeepinMind or standard AcuSense NVR may be a more cost-appropriate fit. Similarly, if your timeline cannot accommodate the 6-8 week special order lead time, a stocked model should be considered instead.
- Choose a different model if: Your deployment consists entirely of AcuSense cameras that already perform perimeter protection and human/vehicle classification at the camera level – in that scenario, the full NVR-side AI engine capability of this model may not be required, and a recorder focused on high channel count and storage may be sufficient.
FAQs
- Does the iDS-9664NXI-M8/X come with hard drives included?
No. The iDS-9664NXI-M8/X is supplied without HDDs. It supports up to 8 SATA drives with a maximum of 10 TB per drive, giving a maximum raw capacity of 80 TB. Surveillance-grade drives are recommended for continuous 24/7 recording workloads. Suitable drives are available separately.
- How does the dual AI engine architecture work on this NVR?
The iDS-9664NXI-M8/X has 2 independent AI engines, each capable of running one intelligent algorithm at a time. The engine mode is adjustable, so administrators can assign one engine to facial recognition and the other to perimeter protection, for example, allowing both functions to run simultaneously across their respective channel limits.
- What is the difference between facial recognition by NVR and facial recognition by camera on this unit?
When using NVR-side processing, facial detection and analytics supports up to 16 channels for live video streams (8-ch per engine) and up to 48 channels for face picture comparison (24-ch per engine). When AI-capable cameras are connected and perform their own facial recognition, the results are passed to the NVR for all connected channels, extending coverage well beyond what the NVR engines alone can handle.
- Can the iDS-9664NXI-M8/X perform perimeter protection on cameras that are not AcuSense models?
Yes. NVR-side perimeter protection processes video from standard IP cameras using the NVR’s own deep learning engines. Without the Large Model, it supports up to 24-ch at 2 MP, 16-ch at 4 MP, or 8-ch at 8 MP. When AcuSense cameras are connected, perimeter protection powered by the Large Model extends to all channels via camera-side processing.
- What RAID configurations are supported for storage redundancy?
The iDS-9664NXI-M8/X supports RAID 0, 1, 5, 6, and 10 across its 8 SATA bays. RAID 5 and RAID 6 are commonly used in enterprise surveillance deployments to provide drive failure tolerance while maintaining high usable capacity. The appropriate RAID mode will depend on your redundancy requirements and acceptable storage overhead.
- What is AcuSearch and how many channels does it support on this NVR?
AcuSearch is a metadata-driven search function that allows operators to retrieve recorded footage based on structured AI tags rather than manual timeline scrubbing. By NVR processing, up to 8 channels and up to 691,200 targets per day are supported. When cameras with AcuSearch capability are connected, all channels contribute to the searchable target database, significantly increasing retrieval scale.
- What is the lead time for the iDS-9664NXI-M8/X and can it be ordered for an urgent project?
The iDS-9664NXI-M8/X is a special order item with an estimated lead time of approximately 6-8 weeks. This should be factored into project timelines at the planning stage. If your installation has a shorter delivery window, contact Security Wholesalers to discuss current stock availability or suitable alternatives before committing to this model.
- Is the iDS-9664NXI-M8/X compatible with third-party IP cameras, or is it limited to Hikvision cameras?
The NVR supports standard ONVIF and RTSP protocols, which allows connection of many third-party IP cameras. However, AI features such as NVR-side perimeter protection, facial recognition, AcuSearch, and video structuralization function at full capacity when connected with compatible Hikvision cameras. Third-party cameras connected via ONVIF may have limited or no access to the NVR’s AI analytics capabilities depending on the metadata the camera provides.
