The DHI-NVR5216-EI is a 16-channel, 1U network video recorder from Dahua’s WizSense series, designed for businesses that need dense channel support without stepping up to a rack-mounted chassis. It’s a strong fit for mid-sized commercial sites running a large number of cameras across multiple zones.
This recorder supports IP camera resolutions up to 32 MP and delivers a maximum decoding capability of 32 channels at 1080p@30fps, or 16 channels at 4MP@30fps. Bandwidth reaches 384 Mbps for incoming, recording, and outgoing streams, scaling down to 200 Mbps when AI processing is active.
On the AI side, the DHI-NVR5216-EI handles 2-channel face detection and recognition, 4-channel perimeter protection, and 8-channel SMD Plus filtering onboard, with support for up to 20 face databases holding 20,000 images. When paired with compatible Dahua cameras, it also unlocks ANPR, video metadata, stereo analysis, heat mapping, PPE detection, and smart sound detection, extending intelligence across all 16 channels.
A standout feature of this model is AcuPick support across all 16 channels, helping operators quickly locate specific footage using object- and attribute-based search rather than manual scrubbing. It also supports EPTZ and one-click arming and disarming for faster operational control.
Storage is handled through two SATA bays, each supporting up to 20 TB, along with N+M clustering and iSCSI support for teams planning scalable, redundant storage setups. Video output covers 4K HDMI and VGA, with heterogeneous source configuration so each display can show different content simultaneously.
Built on an industrial-grade processor with embedded Linux, the DHI-NVR5216-EI supports ONVIF, CGI, and SDK integration alongside third-party camera compatibility from brands like Axis, Sony, Panasonic, and Hanwha, making it a flexible option for mixed-vendor installations.
For organizations running larger camera counts that still want a compact 1U footprint, strong AI coverage, and flexible storage scalability, the DHI-NVR5216-EI is a well-balanced choice.
