DHI-NVR4108HS-EI is a compact 8-channel network video recorder from Dahua’s WizSense series, built for surveillance projects that need serious AI analytics without stepping up 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-style intelligence.
The DHI-NVR4108HS-EI supports IP camera resolutions up to 16MP across 8 channels, with adaptive decoding capability reaching up to 16 channels at 1080p@30fps. Network bandwidth totals 80 Mbps for incoming, recording, and outgoing streams, giving reliable performance even under demanding multi-camera loads.
Where the DHI-NVR4108HS-EI 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, it extends 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-NVR4108HS-EI well suited for access control, retail analytics, and identity-aware security applications.
Video compression relies on Smart H.265+, H.265, Smart H.264+, H.264, and MJPEG, keeping storage requirements manageable even with AI-heavy recording. The unit includes one SATA HDD bay supporting drives up to 20TB, with the drive sold separately so users can choose capacity to match their retention needs.
Video output includes simultaneous or heterogeneous HDMI and VGA with maximum resolution up to 4K (3840×2160), giving clear detail for both live monitoring and reviewing AI-flagged events. Camera compatibility extends beyond ONVIF to include native support for Panasonic, Sony, Hanwha, Axis, Pelco, Arecont, and Canon devices.
Compact at 0.84kg, this recorder is a strong fit for schools, retail stores, hotels, and clinics that need facial recognition, people counting, and behavior analytics in a straightforward, cost-effective 8-channel package.
