DHI-NVR4216-4KS3 is a 16-channel network video recorder built for surveillance projects that need more storage headroom and expanded alarm connectivity in a single 1U enclosure. Featuring two HDD bays instead of one, this recorder is a strong fit for businesses that expect longer retention periods or heavier recording loads across their camera network.
The DHI-NVR4216-4KS3 supports IP camera resolutions up to 12MP, with network bandwidth reaching 160 Mbps incoming, 160 Mbps recording, and 80 Mbps outgoing when AI is disabled, or 80/80/60 Mbps with AI features active. This flexibility lets installers balance channel count against analytics performance depending on the deployment.
Built-in AI capability is a key strength of the DHI-NVR4216-4KS3. Beyond onboard SMD (Smart Motion Detection), the recorder supports camera-based face detection with attribute recognition covering gender, age group, glasses, expressions, and face masks, along with face recognition across all channels at up to 6 targets per second. Perimeter protection extends across 6 channels, and the system also handles people counting, stereo analysis, and heat mapping when paired with compatible AI cameras.
SMD Plus adds a further layer of accuracy, running secondary filtering across 4 channels on the recorder and up to 12 targets per second by camera, significantly reducing false alerts caused by leaves, rain, or lighting changes. Decoding capability reaches up to 8 channels at 1080p@30fps for smooth multi-camera playback.
What sets the DHI-NVR4216-4KS3 apart from single-bay models is its dual SATA HDD interface, supporting up to 20TB per drive along with disk group functionality for organizing storage by camera or channel. It also adds 4-channel alarm input and 2-channel alarm output, giving integrators more flexibility for connecting external sensors and triggering physical alarm devices.
Video compression relies on Smart H.265+, H.265, Smart H.264+, and H.264, keeping storage efficient across a larger channel count. Video output includes simultaneous HDMI and VGA up to 4K (3840×2160) resolution, with flexible multi-screen display layouts of 1, 4, 8, 9, or 16 channels. Camera compatibility extends beyond ONVIF to include native support for Panasonic, Sony, Axis, Arecont, Pelco, Canon, and Hanwha devices.
Weighing 1.49kg and operating reliably across a -10°C to +55°C range, the DHI-NVR4216-4KS3 is a solid choice for growing businesses that need extended storage capacity, richer alarm integration, and AI-powered analytics across a full 16-camera system.
