DHI-NVR4108HS-4KS3 is a compact 8-channel network video recorder that delivers advanced AI-powered analytics across a larger camera network while staying in a space-saving 1U enclosure. Built with an industrial-grade processor and embedded Linux operating system, it’s designed for users who need more than basic motion detection.
The DHI-NVR4108HS-4KS3 supports IP camera resolutions up to 12MP across 8 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 options whether monitoring several high-resolution feeds or a full set of standard-definition cameras.
The standout feature of the DHI-NVR4108HS-4KS3 is its expanded AI capability, running perimeter protection across 6 channels along with camera-based face detection and face recognition, each processing up to 6 targets per second across all channels. Face attribute recognition covers gender, age group, glasses, expressions, face masks, and beards, giving detailed identification data for security and access scenarios. The recorder also supports people counting, stereo analysis, and heat mapping when paired with compatible cameras.
SMD Plus adds another layer of accuracy, applying secondary filtering across 4 channels on the recorder and up to 12 targets per second by camera, reducing false alarms caused by leaves, rain, or shifting light conditions. This combination of AI features makes the DHI-NVR4108HS-4KS3 well suited for retail security, access monitoring, and people-flow analysis.
Video compression uses Smart H.265+, H.265, Smart H.264+, and H.264 codecs to manage storage efficiently even with 8 channels recording AI-enhanced footage. The unit includes one SATA HDD bay supporting drives up to 20TB, with backup available through USB device or network. Camera compatibility extends beyond ONVIF to include native support for Panasonic, Sony, Axis, Arecont, Pelco, Canon, and Hanwha devices.
Video output includes simultaneous HDMI and VGA up to 4K (3840×2160) resolution, with flexible main and sub-screen display layouts of 1, 4, 8, or 9 channels. Remote access is available via P2P with dedicated iOS and Android mobile apps.
Compact at 0.81kg, the DHI-NVR4108HS-4KS3 operates reliably across a -10°C to +55°C range and carries CE certification, making it a strong pick for anyone who wants facial recognition and analytics across a full 8-camera surveillance system without moving to an enterprise-tier recorder.
