Dahua DHI-NVR4216-EI — 16-Channel 4 Series Network Video Recorder
The Dahua DHI-NVR4216-EI is a 16-channel network video recorder from Dahua's 4 Series, built to support IP cameras up to 16 MP in resolution.

Who is it for?
An NVR (Network Video Recorder) receives, records and manages footage from IP cameras over your network, giving you central storage, remote viewing and playback. With 16 channels, the DHI-NVR4216-EI suits small to medium sites such as retail units, offices, warehouses or multi-camera residential installs where a mix of general recording and AI-assisted alerts (face recognition, perimeter protection) is needed without the cost of a PoE-integrated recorder.

What you will need

- This NVR has no built-in PoE ports, so IP cameras will need a separate PoE switch to provide power and data over Ethernet
- An HDMI or VGA monitor for initial setup and local viewing
Frequently asked questions
How many cameras can I connect to the DHI-NVR4216-EI?
It supports up to 16 IP cameras, with each channel able to record resolutions up to 16 MP depending on your decoding configuration.
Does it need special cameras for face recognition?
Face detection and recognition can run on the recorder itself (1 channel) or be offloaded to compatible Dahua AI cameras across more channels, so standard Dahua IP cameras work without extra licensing.
Is there a monthly fee to use this NVR?
No. Recording, playback and AI analysis run locally on the unit and via the free Dahua mobile app — there's no subscription required for standard use.
Will this NVR work with non-Dahua IP cameras?
Yes, it supports ONVIF (Profile S/T/G) as well as native integration with several third-party brands including Panasonic, Sony, Axis and Pelco.
