8-Channel 4K Decoding with Integrated 8-Port PoE

The Dahua DHI-NVR4208-8P-4KS3 is a high-performance 8-channel 1U Network Video Recorder engineered for small-to-medium commercial spaces, retail stores, and residential security setups. Supporting IP camera resolutions up to 12 MP and 4K HDMI output (3840 × 2160), it delivers high-definition live view and playback. Featuring 8 built-in PoE ports with a generous 130 W power budget, installers can connect, power, and configure smart IP cameras over single Ethernet cables without extra switches.

Intelligent SMD Plus and Smart Camera AI Integration

Equipped with on-board SMD Plus by Recorder across 4 channels, the unit accurately classifies humans and vehicles to eliminate false triggers caused by falling leaves, rain, or lighting shifts. When paired with smart Dahua AI cameras, the NVR seamlessly processes up to 6-channel perimeter protection, face detection and recognition, people counting, stereo analysis, and crowd heat mapping.

Dual SATA Storage, Smart Compression, and Alarm I/O

  • High-Capacity 2-Bay Storage: 2 SATA interfaces support up to 20 TB per hard drive (40 TB total) for extended local recording retention.
  • Efficient Smart H.265+ Codec: Significantly optimizes network bandwidth and storage consumption without sacrificing 4K image quality.
  • Multi-Screen Display Options: Simultaneous and heterogeneous display modes across HDMI (up to 4K) and VGA (up to 1080p) outputs.

FAQ

Does this NVR power IP cameras directly through network cables?

Yes. The NVR4208-8P-4KS3 includes 8 integrated PoE ports (IEEE 802.3af/at) with a total power budget of 130 W (up to 25.5 W per port), delivering plug-and-play power and data over standard Ethernet cables.

What is the difference between AI by Recorder and AI by Camera on this unit?

AI by Recorder uses the NVR's internal processor to run 4-channel SMD Plus on standard video streams. AI by Camera supports advanced analytics—such as 6-channel perimeter protection, face recognition, and people counting—offloaded directly from compatible smart IP cameras.

How much storage capacity does this NVR support?

The recorder features 2 SATA hard drive bays that each accommodate up to a 20 TB drive, providing a maximum raw capacity of 40 TB. Hard drives are sold separately.

Can this recorder output video to a 4K TV or monitor

Yes. The HDMI port supports 4K resolution (3840 × 2160), while the VGA port supports up to 1080p, allowing flexible simultaneous or heterogeneous dual-screen monitoring.
