Hikvision DS-9664NI-M8 – M Series 8K NVR

If you’re running a larger camera system (or planning to), the DS-9664NI-M8 is built to keep things smooth and dependable. With 64-channel IP camera input, 8K/dual 4K outputs, and up to 400 Mbps incoming/outgoing bandwidth, it’s designed for high-resolution video without the bottlenecks that can cause choppy live view or slow playback. Add RAID support to help protect recordings, and you’ve got an NVR that’s ready for serious, always-on surveillance.

Key Features (Buyer Benefits)

  • Up to 64-ch IP camera inputs — room to scale without swapping your recorder later.
  • Up to 400 Mbps incoming + 400 Mbps outgoing bandwidth — keeps live view and remote access responsive under load.
  • 2 HDMI + 2 VGA (different source) — run a main monitor and an auxiliary monitor without compromises.
  • 8K or dual 4K video outputs — sharp multi-camera viewing for control rooms and security desks.
  • H.265+ compression — reduces storage needs (up to 75%) so you spend less on drives over time.
  • RAID 0/1/5/6/10 + N+M hot spare — helps reduce data-loss risk if a drive fails.
  • Supports special cameras (people counting, ANPR, fisheye) — makes advanced deployments easier to manage.
  • Advanced streaming technology — smoother live view when network conditions aren’t perfect.
  • Up to 8-ch IP speakers can be connected — add audio capability for deterrence or announcements.

Ideal Applications / Common Uses

  • High-channel-count sites — warehouses, campuses, office parks, multi-building properties.
  • High-resolution deployments — where 8 MP–32 MP cameras are used and you want smooth decoding/playback.
  • Security control rooms — multi-display monitoring with independent HDMI/VGA outputs.
  • Business intelligence add-ons — people counting, ANPR, heat map, and POS overlay environments.
  • Recordings that matter — RAID-capable setups to reduce the risk of losing evidence from a drive failure.
