Overview
The DS-7616NXI-I2/16P/S(E) is a 1U, 16-channel AcuSense NVR with 16 integrated PoE ports and on‑board AI analytics for human/vehicle filtering, perimeter protection and facial search. Suitable for SMB and commercial CCTV installations that require onboard analytics and PoE camera power.

• 16 PoE ports (IEEE 802.3af/at) with a total PoE budget ≤ 200 W.
• AcuSense deep‑learning analytics: human/vehicle filtering, perimeter protection (engine‑limited channels may apply) and facial recognition / search.
• High‑resolution support: records up to 12MP (device/firmware dependent); HDMI output up to 4K; synchronous 16‑channel playback at 1080p.
• Efficient compression: H.265+/H.265/H.264+/H.264 with dual‑stream support.
• Storage: 2 × hot‑plug SATA bays (check drive compatibility; datasheet references up to 10 TB per disk for some variants).

Ideal use cases
Multi‑camera retail, offices, education sites and small commercial deployments where integrated PoE and AI‑driven false‑alarm reduction improve operational efficiency and monitoring.

Compliance & safety
Confirm CE/UKCA marking and local approvals with your supplier. Installation should be performed by a qualified technician. Isolate mains power before servicing. Follow manufacturer instructions for network configuration, hard‑drive fitting and firmware updates.

Notes
Some advanced features (for example running facial recognition and perimeter protection simultaneously) may be limited by the device engine; refer to the official datasheet for channel/engine constraints. HDDs are typically not included — check whether you sell as NVR‑only or as a bundled kit with pre‑installed drives or services.
