Key Capabilities
128-Channel IP Camera Support
Connect up to 128 IP cameras at resolutions up to 32 megapixels, making this NVR suited to large campuses, multi-building facilities, or any deployment where a single recorder needs to consolidate a high volume of camera feeds without splitting across multiple units.
8K HDMI Video Output
HDMI 3 supports ultra-high-definition 8K output, enabling detailed multi-camera display walls or single-screen overview setups in control rooms. Multiple HDMI outputs provide flexible configuration for operators monitoring different zones simultaneously.
AcuSense AI Analytics
Built-in AcuSense intelligence supports facial recognition across up to 64 face libraries with storage for 300,000 face images, perimeter protection, video structuralization, and AcuSearch for fast event retrieval across hundreds of hours of footage from 128 cameras.
480TB Storage with RAID Protection
24 SATA interfaces each support drives up to 20TB, reaching 480TB total capacity. RAID 0, 1, 5, 6, and 10 configurations plus N+M hot spare support protect recorded footage against drive failure without requiring system downtime for replacement in critical surveillance environments.
Redundant Power Supply
Dual redundant power supplies ensure the DS-96128NXI-S24R continues operating if one power unit fails. For 24/7 installations in transport hubs, hospitals, or critical infrastructure, this hardware redundancy removes a common single point of failure from the recording chain.
4 x 2.5 Gbps Ethernet Ports
Four dedicated 2.5 Gbps network interfaces provide the throughput needed to handle 1280 Mbps incoming bandwidth from 128 high-resolution cameras. This multi-port design also allows network segmentation between camera traffic and management access on larger enterprise installations.
Best For
- Enterprise Security Operations: Facilities requiring a single recorder to consolidate up to 128 high-resolution cameras with AI-powered search and facial recognition across a centralised control room.
- Transport Hubs and Airports: High-throughput environments where continuous recording, rapid event retrieval via AcuSearch, and hardware redundancy from dual PSUs are non-negotiable operational requirements.
- Universities and Hospital Campuses: Multi-building deployments needing scalable storage up to 480TB, long retention periods supported by RAID configurations, and AI analytics for perimeter and access monitoring.
- City Surveillance and Smart City Projects: Large-volume deployments where channel density, bandwidth headroom at 1280 Mbps incoming, and structured video data via video structuralization deliver operational value at scale.

Why Choose the DS-96128NXI-S24R
At the 128-channel enterprise tier, the DS-96128NXI-S24R separates itself from mid-range NVRs through a combination of features that lower-capacity recorders simply do not offer. RAID 0, 1, 5, 6, 10, and N+M hot spare support means storage architecture can be matched to the actual risk profile of the site, not just bolted on. The dual redundant power supply addresses a hardware failure mode that would be unacceptable in hospitals, transport hubs, or government facilities. AcuSense analytics with support for 64 face libraries and 300,000 face images moves the recorder beyond passive storage into active identification and search, reducing the time investigators spend scrubbing through footage manually. The 4 x 2.5 Gbps Ethernet ports ensure this recorder can handle the sustained bandwidth that 128 cameras at high resolution actually generate. Available through Security Wholesalers, the DS-96128NXI-S24R is stocked for integrators and enterprise procurement teams managing large-scale deployments.
Buyer Decision Tips
Storage and RAID Planning: The DS-96128NXI-S24R supports 24 SATA drives up to 20TB each, but HDDs are not included. Before purchasing, calculate your required retention period based on the number of cameras, frame rate, resolution, and compression format (H.265+ reduces storage significantly compared to H.264). Factor in your chosen RAID configuration, as RAID 5 or 6 will reduce usable capacity from the raw 480TB total. Engaging a certified integrator to calculate storage requirements before ordering drives is recommended for installations at this scale.
Network Infrastructure Requirements: With 4 x 2.5 Gbps interfaces and up to 1280 Mbps incoming bandwidth, the network switches and cabling feeding this recorder need to be sized accordingly. Standard gigabit switches will create a bottleneck when running near full channel capacity. Confirm that your network infrastructure supports 2.5GbE or 10GbE uplinks before deployment, and plan camera subnet segmentation to separate recording traffic from management and client access traffic.

Ideal Use Cases
Airport and Transport Hub Security
Airports and rail terminals running large camera networks benefit from the 128-channel capacity, facial recognition across 64 face libraries, and dual redundant PSUs that maintain continuous recording even if a power unit fails during peak operations.
Hospital and Healthcare Campuses
Healthcare environments covering car parks, entrances, corridors, and secure wards across multiple buildings can consolidate into a single DS-96128NXI-S24R, with RAID-protected storage ensuring footage is retained without data loss in the event of a drive fault.
University and Education Precincts
Tertiary campuses spanning multiple buildings and outdoor areas require extended retention and structured search. The 480TB storage ceiling, H.265+ compression, and AcuSearch functionality allow security teams to locate specific events quickly across weeks of recorded footage.
Smart City and Public Infrastructure
City-wide camera networks feeding a central operations centre benefit from the 128-channel headroom, 1280 Mbps incoming bandwidth, and 4 x 2.5 Gbps Ethernet ports that provide the network throughput to absorb simultaneous high-resolution streams from cameras across a wide geographic area.
Industrial Facilities and Logistics Parks
Warehouses, manufacturing facilities, and logistics sites with extensive perimeter and internal coverage can connect up to 8 IP speakers alongside 128 cameras, enabling coordinated monitoring and active response from a single recorder platform.
Government and Critical Infrastructure
Sites where footage integrity is a legal or operational requirement benefit from N+M hot spare RAID support, which allows failed drives to be replaced without halting recording, combined with the redundant PSU design that removes power failure as a recording interruption risk.
Choosing the Right Model
- Choose this model if: Your deployment requires 128 channels of IP camera recording, needs AI-powered facial recognition with large face libraries, demands RAID-protected storage scaling to 480TB, or operates in a critical environment where dual redundant power supplies and N+M hot spare drive configuration are required to meet uptime obligations.
- Choose a different model if: Your camera count is below 64 channels, as a lower-channel NVR will deliver the same recording and AI capabilities at a lower hardware cost and with a smaller physical footprint. If rack space is constrained and drive bays beyond 8 or 16 are not needed, a mid-range NVR will fit the deployment more efficiently without unused capacity.
FAQs
- How many cameras can the DS-96128NXI-S24R support simultaneously?
The DS-96128NXI-S24R supports up to 128 IP cameras connected simultaneously. Cameras up to 32 megapixels are supported, and the recorder handles up to 1280 Mbps of incoming bandwidth across its 4 x 2.5 Gbps Ethernet ports to manage high-resolution streams from a full channel load.
- What RAID configurations are supported, and which is recommended for critical deployments?
The recorder supports RAID 0, 1, 5, 6, 10, and N+M hot spare. For mission-critical environments, RAID 6 allows 2 simultaneous drive failures without data loss, while N+M hot spare enables automatic drive rebuild using a standby drive without manual intervention. The appropriate RAID level depends on your balance between usable capacity and fault tolerance.
- Does the DS-96128NXI-S24R include hard drives?
No, hard drives are not included. The recorder provides 24 SATA bays, each supporting drives up to 20TB, for a maximum raw capacity of 480TB. Drives need to be purchased separately and should be surveillance-rated HDDs designed for continuous write operations. Factor in RAID overhead when calculating usable storage for your retention requirements.
- What AI analytics features does this NVR support?
The DS-96128NXI-S24R includes AcuSense analytics supporting facial recognition with up to 64 face libraries and 300,000 stored face images, perimeter protection, video structuralization, and AcuSearch for rapid event-based footage retrieval. These features require compatible AcuSense cameras to function and operate at the recorder level rather than requiring cloud processing.
- How does the redundant power supply work in practice?
The dual redundant power supply means the unit contains 2 independent PSUs. If 1 fails during operation, the second maintains full power to the recorder without interruption. For installations in hospitals, airports, or government facilities where recording continuity is mandatory, this design removes power supply failure as a risk to footage availability.
- What video output options are available for control room display setups?
The DS-96128NXI-S24R provides multiple HDMI outputs. HDMI 3 supports output at up to 8K resolution, which is suited to large-format displays or video walls in security operations centres.
