Hikvision DS-9664NI-M16 64-Channel 3U 8K NVR

The Hikvision DS-9664NI-M16 is a 64-channel M Series 8K network video recorder, built in a 3U chassis to accommodate a larger number of hard drives than the 2U variants in the same range. It targets sites that need both a high camera count and genuinely high-resolution monitor output, supporting simultaneous 8K and dual 4K video display, RAID-protected storage and a mix of specialist cameras such as fisheye, ANPR and people-counting units on the same system.

Hikvision DS-9664NI-M16 64-Channel 3U 8K NVR

With up to 64 IP camera inputs and 400 Mbps of both incoming and outgoing bandwidth, the DS-9664NI-M16 is designed for control-room style deployments where a large number of feeds need to be recorded, viewed and exported reliably. Decoding capacity is tiered by resolution — from 2 channels at 32MP down to 32 channels at 1080p — so the recorder can be matched to camera estates 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 a primary monitoring wall and a secondary auxiliary display simultaneously, with HDMI 1 capable of true 8K output at 30Hz (dropping HDMI 2 to 1080p only in that specific mode) or dual 4K/60Hz across both HDMI outputs when 8K isn't required. This flexibility matters for control rooms that want the option of a single very high-resolution main display alongside a secondary feed, without needing a second recorder.

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 — noting that when HDMI 1 is set to 8K, HDMI 2 is limited to 1080p. Both VGA outputs support 1080p at 60Hz. HDMI 1 and VGA 1 work together as the main output; HDMI 2 and VGA 2 work together as the auxiliary output.

RAID-Protected Storage

The recorder supports RAID 0, 1, 5, 6 and 10, along with N+M hot spare configurations, giving installers a range of options to balance storage capacity against redundancy depending on how critical continuous recording is for the site.

Special Camera Support & Audio

The DS-9664NI-M16 supports specialist camera types including people-counting cameras, ANPR (automatic number plate recognition) cameras and fisheye cameras alongside standard IP cameras. Up to 8 channels of IP speakers can be connected for site-wide audio alerts, and 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 with a high on-board drive count (3U chassis)
• Facilities using specialist cameras (ANPR, people counting, fisheye)
• Mission-critical sites needing RAID-protected, hot-spare storage
• 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

Can the DS-9664NI-M16 output true 8K video?

Yes, HDMI 1 supports 7680 × 4320 at 30Hz. Note that when HDMI 1 is set to this 8K mode, HDMI 2 is limited to 1080p output, so you can't run two independent 8K displays at once.

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 — so actual channel usage depends on the resolution mix in your camera estate.

What RAID levels does it support?

RAID 0, 1, 5, 6 and 10, along with N+M hot spare configurations, giving flexibility to prioritise either capacity or redundancy depending on how critical continuous recording is for the installation.

Why is this a 3U chassis rather than 2U?

The larger 3U chassis accommodates more hard drive bays than the 2U variant in the same series, which matters for sites needing large on-board storage capacity or higher-redundancy RAID configurations.

Does it support special camera types like ANPR or fisheye?

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

Can I connect IP speakers for audio alerts?

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

What is the difference between the main and auxiliary video 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, allowing two separate monitoring feeds from one recorder.

Does it handle unreliable network connections well?

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