DHI-NVR4104HS-4KS3 is a compact 4-channel network video recorder that brings advanced AI-powered analytics to small and mid-sized surveillance deployments. Built with an industrial-grade processor and embedded Linux operating system in a space-saving 1U design, this model steps up from basic motion detection into a much richer set of intelligent features.
The DHI-NVR4104HS-4KS3 supports IP camera resolutions up to 12MP across 4 channels, with network bandwidth of 80 Mbps incoming, 80 Mbps recording, and 60 Mbps outgoing. Decoding capability reaches up to 8 channels at 1080p@30fps, giving flexible viewing options for mixed-resolution camera setups.
What sets the DHI-NVR4104HS-4KS3 apart is its expanded AI toolkit. Beyond built-in SMD (Smart Motion Detection) processed by the recorder itself, it supports camera-based face detection with attribute recognition including gender, age group, glasses, expressions, and face masks, plus face recognition across all channels. It also handles perimeter protection, people counting, stereo analysis, and heat mapping when paired with compatible cameras — features typically reserved for higher-tier recorders.
SMD Plus adds a further layer of accuracy, applying secondary filtering across 4 channels to separate genuine human and vehicle movement from false triggers like leaves, rain, or changing light. This significantly reduces nuisance alerts compared to standard motion detection alone.
Video compression relies on Smart H.265+, H.265, Smart H.264+, and H.264 codecs to manage storage efficiently. The unit includes one SATA HDD bay supporting drives up to 20TB, with backup available through USB device or network. For camera compatibility, the DHI-NVR4104HS-4KS3 goes beyond standard ONVIF support to include native integration with Panasonic, Sony, Axis, Arecont, Pelco, Canon, and Hanwha cameras.
Video output includes simultaneous HDMI and VGA up to 4K (3840×2160) resolution, with dual main/sub-screen display options. Remote access is available through the P2P protocol with dedicated iOS and Android mobile apps.
Compact at just 0.81kg, the DHI-NVR4104HS-4KS3 operates reliably across a -10°C to +55°C range and carries CE certification. It’s a strong choice for users who want facial recognition and people-counting analytics without stepping up to an enterprise-grade recorder.
