Hikvision DS-9664NI-M8 64-Channel 2U 8K NVR

The Hikvision DS-9664NI-M8 is a 64-channel M Series 8K network video recorder in a 2U chassis, offering the same 8K/dual-4K video output and RAID-protected storage as its 3U sibling but in a more compact enclosure with a lower drive count. It suits large sites that need 64-channel capacity and genuinely high-resolution monitor output, without necessarily needing the maximum on-board storage the 3U variant provides.

Hikvision DS-9664NI-M8 64-Channel 2U 8K NVR

With up to 64 IP camera inputs and 400 Mbps of both incoming and outgoing bandwidth, the DS-9664NI-M8 is designed for control-room style deployments recording a large number of feeds simultaneously. Decoding capacity is tiered by resolution — from 2 channels at 32MP down to 32 channels at 1080p — allowing the recorder to be matched against a camera estate with a genuine mix of resolutions rather than a single uniform spec.

Two independent HDMI outputs and two VGA outputs allow the recorder to drive both a primary monitoring wall and a secondary auxiliary display at once, with HDMI 1 capable of true 8K output at 30Hz (in which case HDMI 2 is limited to 1080p) or dual 4K/60Hz across both HDMI outputs when 8K isn't required. This is the same output flexibility as the 3U DS-9664NI-M16, but housed in a smaller 2U chassis with fewer drive bays — a relevant trade-off for sites that don't need maximum on-board storage capacity.

8K & Dual 4K Video Output

HDMI 1 supports resolutions up to 8K (7680 × 4320) at 30Hz, 4K at 60Hz or 30Hz, 2K at 60Hz, and 1080p at 60Hz. HDMI 2 supports up to 4K at 60Hz or 30Hz, 2K at 60Hz, or 1080p at 60Hz, dropping to 1080p only when HDMI 1 is set to 8K. Both VGA outputs support 1080p at 60Hz, with HDMI 1/VGA 1 forming the main output and HDMI 2/VGA 2 forming an independent auxiliary output.

RAID-Protected Storage

The recorder supports RAID 0, 1, 5, 6 and 10, plus N+M hot spare configurations, giving installers flexibility to prioritise either raw capacity or redundancy depending on how critical continuous recording is for the deployment. A related European variant, the DS-9664NI-M8/R, instead offers N+1 hot spare with up to 8 HDDs for continuous recording.

Special Camera Support & Audio

The DS-9664NI-M8 supports specialist camera types including people-counting cameras, ANPR cameras and fisheye cameras alongside standard IP cameras, and up to 8 channels of IP speakers can be connected for site-wide audio alerts. Advanced streaming technology helps maintain smooth live view even over degraded network links.

IDEAL FOR

• Control rooms needing a genuine 8K primary display output
• Large sites needing 64 channels in a more compact 2U footprint
• Facilities using specialist cameras (ANPR, people counting, fisheye)
• Sites needing RAID-protected storage without the maximum drive count of the 3U model
• Multi-room monitoring setups needing independent main/auxiliary video feeds
• Retail, transport or logistics sites needing people-counting integration
• Car parks and access roads needing ANPR camera support
• Sites with unreliable network links needing resilient streaming performance

Frequently Asked Questions

How is this different from the DS-9664NI-M16?

Both are 64-channel 8K NVRs with essentially the same video output and RAID capability, but the M16 uses a larger 3U chassis with more drive bays, while this M8 model uses a more compact 2U chassis with a lower drive count — choose based on how much on-board storage and redundancy your site actually needs.

Can it output true 8K video?

Yes, HDMI 1 supports 7680 × 4320 at 30Hz, though HDMI 2 drops to 1080p only when HDMI 1 is running in that 8K mode.

How many cameras can it support?

Up to 64 IP camera channels, with decoding capacity tiered by resolution — for example 2 channels at 32MP or 32 channels at 1080p.

What RAID levels does it support?

RAID 0, 1, 5, 6 and 10, plus N+M hot spare configurations. A related European variant (DS-9664NI-M8/R) instead offers N+1 hot spare with up to 8 HDDs.

Does it support special camera types?

Yes, including people-counting cameras, ANPR (automatic number plate recognition) cameras and fisheye cameras, alongside standard IP cameras.

Can I connect IP speakers for alerts?

Yes, up to 8 channels of IP speakers can be connected for site-wide audible alerts.

What's the difference between the main and auxiliary outputs?

HDMI 1 and VGA 1 work together as the main output, while HDMI 2 and VGA 2 work together as an independent auxiliary output, letting one recorder drive two separate monitoring feeds.

Does it handle unreliable networks well?

Yes, Hikvision's advanced streaming technology is designed to maintain smooth live view even over degraded or congested network links.
