Product Overview
Large-scale IP surveillance deployments demand a recorder that can handle the volume, resolution, and uptime requirements of enterprise environments. The DS-9664NI-M8 is a 64-channel 3RU rack-mount NVR from Hikvision’s M-Series, built for installation in equipment rooms, server racks, and security control centres across campuses, stadiums, government facilities, and industrial sites. Featuring 400Mbps incoming and 400Mbps outgoing bandwidth, it supports up to 64 simultaneous IP camera inputs without compromising throughput. Equipped with 8 SATA bays supporting up to 16TB per drive and full RAID redundancy including N+M hot spare, storage integrity is maintained even under drive failure conditions. It also integrates native support for people counting, ANPR, and fisheye cameras, making it well suited to multi-function deployments where specialised analytics cameras are part of the broader system design. This model ships without HDDs, allowing installers to configure storage to project requirements.
Key Capabilities
64-Channel IP Camera Support
Handles up to 64 simultaneous IP camera inputs, making it appropriate for large-site deployments where a single centralised recorder needs to manage an extensive camera network from one rack-mounted unit.
400Mbps Dual Bandwidth
With 400Mbps incoming and 400Mbps outgoing bandwidth, the DS-9664NI-M8 sustains high-throughput recording and remote streaming across large camera networks without bottlenecking on either ingestion or playback.
8K and Dual 4K Video Output
Two HDMI and 2 VGA interfaces each support independent video sources, with output capability up to 8K or dual 4K. This allows a control room to drive multiple high-resolution display walls or operator stations from a single recorder.
RAID 0, 1, 5, 6, 10 and N+M Hot Spare
Multiple RAID configurations give integrators flexibility to balance storage capacity against redundancy requirements. N+M hot spare support means drives can be replaced during operation without system downtime or data loss.
High-Resolution Decoding Capacity
Capable of decoding up to 2 channels at 32MP, 8 channels at 8MP, or 32 channels at 1080p simultaneously. This decoding headroom is essential for control rooms displaying live feeds from high-megapixel cameras in real time.
Redundant Power Supply
The built-in redundant power supply ensures the recorder continues operating if one power module fails. This is a critical feature for sites where continuous recording uptime cannot be interrupted.
Best For
- Enterprise and Government Facilities: The 64-channel capacity, redundant power supply, and RAID storage make this recorder appropriate for sites where continuity of recording is a compliance or operational requirement.
- Large-Scale Camera Networks: Sites running 33 to 64 IP cameras across warehouses, campuses, or multi-building estates benefit from consolidating feeds into a single 3RU rack-mount unit with sufficient bandwidth headroom.
- Multi-Display Control Rooms: Dual HDMI and dual VGA outputs with independent source support allow operators to configure multi-screen viewing stations or video wall segments from a single recorder.
- Mixed Camera Deployments: Native support for people counting, ANPR, and fisheye cameras means the DS-9664NI-M8 can manage a heterogeneous camera network without compatibility workarounds.
- Sites Requiring High Storage Capacity: With 8 SATA bays each supporting up to 16TB, integrators can configure up to 128TB raw storage to satisfy extended retention requirements at high resolution.
Why Choose the DS-9664NI-M8
At the enterprise end of Hikvision’s NVR range, the DS-9664NI-M8 separates itself from lower-channel recorders through its combination of 64-channel capacity, 400Mbps bidirectional bandwidth, and enterprise-grade storage resilience. Where a 32-channel NVR would require a second unit and separate management overhead for larger sites, the DS-9664NI-M8 consolidates the entire camera network into one 3RU rack-mounted device. The dual HDMI and dual VGA outputs with independent source assignment, 8K output support, and N+M RAID hot spare capability are features absent from mid-tier recorders. The built-in redundant power supply further distinguishes this model for environments where downtime is not acceptable. Available through Security Wholesalers, the DS-9664NI-M8 suits integrators specifying a single, high-capacity recording platform for stadiums, hospitals, logistics centres, or government installations.
Buyer Tip – Storage Planning: This unit ships with no HDDs installed. With 8 SATA bays supporting up to 16TB per drive, storage capacity can range significantly depending on drive selection. Calculate your required retention period based on camera count, resolution, frame rate, and compression format before choosing drive capacity. If RAID 5 or 6 is selected, factor in parity overhead reducing usable storage below raw total.
Buyer Tip – Bandwidth Management: The 400Mbps incoming bandwidth is shared across all 64 channels. High-megapixel cameras at full resolution and frame rate consume significantly more bandwidth per channel than standard 2MP cameras. Map out your camera specifications and confirm total incoming bandwidth stays within the 400Mbps ceiling to avoid dropped frames or recording gaps under load.

Ideal Use Cases
Hospital and Healthcare Campuses
Continuous recording uptime is non-negotiable in healthcare. The DS-9664NI-M8’s redundant power supply and RAID hot spare capability keep recording active even during hardware events, supporting large multi-building hospital deployments.
Logistics and Distribution Centres
Large warehousing and logistics facilities benefit from 64-channel consolidation paired with native ANPR camera support, enabling vehicle tracking and access point monitoring from a single recording platform.
Stadiums and Venues
High camera counts across multiple zones, crowd management analytics via people counting cameras, and high-resolution 8K output for control room displays make this recorder a practical fit for stadium and large venue installations.
Government and Critical Infrastructure
Sites requiring high-availability recording with audit-grade storage integrity benefit from the RAID 5 and 6 configurations and redundant power supply built into the DS-9664NI-M8.
University and Education Campuses
Multi-building campuses running a mix of standard, fisheye, and analytics cameras across dozens of locations can consolidate all feeds into one DS-9664NI-M8 installed in the campus IT or security equipment room.
Choosing the Right Model
- Choose this model if: Your project requires 33 to 64 IP cameras managed from a single recorder, with enterprise storage redundancy (RAID 5/6/N+M), 8K output capability, and a redundant power supply for high-availability operation.
- Choose a different model if: Your camera count is 32 or below – a lower-channel NVR will reduce cost and rack space without sacrificing capability for the actual scale of the deployment. Similarly, if rack space is unavailable, a desktop-form NVR may be more practical for smaller installations.
FAQs
- Does the DS-9664NI-M8 come with hard drives included?
No. The DS-9664NI-M8 is supplied without HDDs. It has 8 SATA bays, each supporting drives up to 16TB. Surveillance-rated drives such as WD Purple or Seagate SkyHawk are recommended. Storage capacity and RAID configuration should be planned based on camera count, resolution, frame rate, and required retention period before purchasing drives.
- What RAID configurations does the DS-9664NI-M8 support?
This recorder supports RAID 0, 1, 5, 6, and 10, as well as N+M hot spare. N+M hot spare allows one or more drives to sit in standby and automatically replace a failed drive, enabling the RAID array to rebuild without manual intervention or system downtime. RAID 5 or 6 is commonly selected for enterprise deployments where both capacity and redundancy are priorities.
- How many cameras can record simultaneously at 4K or higher resolution?
The DS-9664NI-M8 supports up to 64 channels of recording, but decoding for live view is the limiting factor. It can decode up to 8 channels at 8MP (4K), 4 channels at 12MP, or 2 channels at 32MP simultaneously. All 64 channels can record continuously regardless of the live view decoding limit.
- Can the 2 HDMI and 2 VGA outputs show different content simultaneously?
Yes. The product data confirms that all 4 outputs support independent sources, meaning each display can show a different camera layout, channel group, or playback stream. This makes the DS-9664NI-M8 well suited to control rooms running multiple operator workstations or a mix of overview and detail screens.
- Does this NVR support ANPR cameras natively?
Yes. The DS-9664NI-M8 natively supports ANPR cameras, along with people counting and fisheye cameras. This means ANPR events and data from compatible Hikvision ANPR cameras are managed directly within the NVR without requiring a separate analytics server for basic plate capture and logging functions.
- What happens if one of the power supplies fails?
The DS-9664NI-M8 is fitted with a redundant power supply. If one power module fails, the second continues to power the unit without interruption. This is a key differentiator for enterprise installations where uninterrupted recording is required around the clock. Security Wholesalers supplies this model as a complete unit with redundant power fitted as standard.
- How much rack space does the DS-9664NI-M8 require?
The DS-9664NI-M8 occupies 3 rack units (3RU) in a standard 19-inch equipment rack. Before installation, confirm your rack has at least 3RU of free space and adequate airflow clearance above and below the unit. Power and network cabling access at the rear of the rack should also be accounted for during rack layout planning.
