The Dahua DHI-NVR2216-4KS3 is the dual-HDD version of the 16-channel 4K WizSense NVR — the same 12MP recording, 4K HDMI output and WizSense AI (SMD Plus + perimeter protection), with two SATA bays for far more retention or disk redundancy.
Efficient Smart H.265+, ONVIF compatibility with Dahua and third-party cameras, and the DMSS mobile app complete it. Note: no built-in PoE — pair with a suitable PoE switch (we include the right one). The choice when you need longer history or resilience on a 16-camera 4K system.
🗄️ Two Drive Bays
Double the storage for long retention, or mirror footage for redundancy against a disk failure.
🧠 AI + 4K
SMD Plus and perimeter alerts with 12MP recording and 4K output on a resilient dual-disk box.

❓ Frequently Asked Questions
2216 or 2116? The 2216 (this) has 2 HDD bays for more capacity or redundancy; the 2116 is the single-disk version — same 4K/AI features.
Why dual HDD? Two bays double storage for long retention, or mirror footage so a single disk failure doesn’t lose your history.
Does it power cameras? No built-in PoE — cameras run off a separate PoE switch, which we include.
Hard disks included? No — we supply surveillance-grade drives sized to your plan.
