Hikvision DS-7604NI-M1/4P – M Series 8K NVR

Need a clean, reliable way to run up to 4 IP cameras without extra PoE switches or complicated wiring? The DS-7604NI-M1/4P is built for practical installs—sharp 8K HDMI output for clear viewing, efficient H.265+ storage savings, and secure stream transmission features that help keep video access under control.

If you’re trying to simplify your setup (and stop wasting time dealing with bandwidth/storage headaches), this NVR keeps things straightforward: power cameras via PoE, record efficiently, and manage playback without friction.

Key Features

  • H.265+/H.265/H.264+/H.264 video formats — keeps compatibility flexible while helping reduce storage costs.
  • Up to 4-ch IP camera inputs — sized right for small-to-mid deployments without overbuying.
  • Up to 4-ch@8 MP decoding capacity — smooth live view/playback without the “lag and guess” feeling.
  • Up to 40 Mbps incoming bandwidth — supports stable multi-camera recording in real-world networks.
  • H.265+ compression reduces storage space by up to 75% — store more days of video before you have to expand HDDs.
  • Dual-stream recording — saves bandwidth while keeping usable quality where it matters.
  • Stream over TLS encryption — more secure stream transmission service for networked viewing.
  • Support double verification for playback and downloading — helps prevent “anyone can pull footage” problems.
  • Independent HDMI and VGA outputs — easy integration with different monitors (or keep a local VGA while HDMI runs the main display).
  • HDMI video output at up to 8K resolution — crisp detail on capable displays for better situational awareness.
  • 1 SATA interface for HDD connection — straightforward storage expansion.
  • 4-ch synchronous playback — review multiple camera angles at once without juggling.
  • Multiple VCA events + special camera smart functions support — motion/line crossing/intrusion, heat map, ANPR, people counting (camera-dependent features).
  • POS information overlay + POS triggered recording/alarm — faster incident review for retail and transaction-heavy sites.
  • 4 independent PoE network interfaces — power cameras directly from the NVR for simpler installs.
  • 1 self-adaptive 10/100/1000 Mbps Ethernet interface — stable backbone connection to your network.
  • Hik-Connect & DDNS — easier network management and remote access workflows.
  • Smooth streaming technology + web access without plug-in — less friction for everyday viewing/management.

Ideal Applications (Common Uses)

  • Small businesses & offices — a clean 4-camera NVR setup that’s easy to manage.
  • Retail & front-counter monitoring — POS overlay support helps speed up transaction-based reviews.
  • Warehouses & stock rooms — multi-camera playback makes it easier to track movement and access events.
  • Clinics & professional buildings — secure playback/downloading controls support tighter access.
  • Remote oversight sites — Hik-Connect/DDNS features support practical network management.
