Hikvision DS-7608NXI-K2/8P — 8-ch PoE 1U K Series AcuSense 4K NVR

If you want an NVR that’s simple to deploy but still “smart” enough to cut the noise, the DS-7608NXI-K2/8P is built for exactly that. With 8 built-in PoE ports, you can connect compatible IP cameras and power them from the recorder—fewer adapters, fewer installation headaches. And with AcuSense + Motion Detection 2.0, it’s designed to help reduce false alarms (so you’re not chasing shadows) while keeping playback and search faster when you actually need evidence.

Key Features

  • Up to 8-ch IP camera inputs + 8 PoE interfaces — plug & play style installs that keep wiring clean and time-to-live faster.
  • H.265+/H.265/H.264+/H.264 support — more efficient storage so you can keep video longer without constantly expanding drives.
  • Up to 80 Mbps incoming bandwidth — handles multiple cameras smoothly for reliable recording performance.
  • 4K HDMI output + independent HDMI/VGA — crisp local viewing for live monitoring and review on higher-res displays.
  • AcuSense + Motion Detection 2.0 — helps minimize manual effort and security costs by reducing false alarms and improving search/playback efficiency.
