DHI-NVR4116HS-EI is a compact 16-channel network video recorder from Dahua’s WizSense series, built for surveillance projects that need serious onboard AI without moving to a rack-mounted system. Powered by an industrial-grade processor and embedded Linux, it fits into a space-saving 1U enclosure while delivering enterprise-level intelligence for a full 16-camera network.
The DHI-NVR4116HS-EI supports IP camera resolutions up to 16MP, with adaptive decoding capability reaching up to 16 channels at 1080p@30fps. Network bandwidth is generous, totaling 256 Mbps for incoming, recording, and outgoing streams with AI disabled, or 180 Mbps across the board when AI features are active.
Where the DHI-NVR4116HS-EI truly stands out is its onboard AI processing. The recorder itself handles 1-channel face detection and recognition, storing up to 10 face databases with 20,000 face images (2.5GB total capacity), along with 2-channel perimeter protection supporting 10 IVS rules per channel, and 4-channel SMD Plus for accurate motion filtering. When paired with compatible Dahua AI cameras, capabilities extend to face detection, face recognition, perimeter protection, SMD, ANPR, people counting, stereo analysis, and heat mapping across all connected channels, each processing up to 8 targets per second.
Face attribute recognition covers gender, age group, glasses, expressions, face masks, and beards, and each stored face profile can include name, gender, birthday, address, and credential details, making the DHI-NVR4116HS-EI well suited for access control, retail analytics, and identity-aware security applications across larger properties.
Video compression relies on Smart H.265+, H.265, Smart H.264+, H.264, and MJPEG, keeping storage manageable even with 16 channels of AI-enhanced recording. The unit includes one SATA HDD bay supporting drives up to 20TB, sold separately so users can select capacity to match their retention needs.
Video output includes simultaneous or heterogeneous HDMI and VGA with maximum resolution up to 4K (3840×2160), plus flexible multi-screen display layouts of 1, 4, 8, 9, or 16 channels. The network port runs on Gigabit Ethernet (10/100/1000 Mbps) to support the higher throughput a 16-channel AI system demands, and camera compatibility extends beyond ONVIF to include native support for Panasonic, Sony, Hanwha, Axis, Pelco, Arecont, and Canon devices.
Compact at 0.81kg, the DHI-NVR4116HS-EI is a strong fit for schools, retail chains, hotels, and office buildings that need facial recognition, people counting, and behavior analytics across a full 16-camera surveillance system.
