Hikvision DS-2CD2446G2‑I (2.8mm)(C) — 4 MP fixed‑focal indoor cube network camera with built‑in AcuSense analytics. Ideal for offices, retail and other indoor surveillance where accurate human/vehicle classification and low‑light performance are required.

• 4 MP (2688 × 1520) 1/3" progressive CMOS sensor with DarkFighter low‑light enhancements and 120 dB WDR.
• AcuSense deep‑learning analytics: human/vehicle classification, face capture and perimeter protection to reduce false alarms.
• 2.8 mm fixed lens (≈102.7° H FOV); IR illumination to ~10 m for B/W night mode; minimum illumination 0.003 lux (colour).
• H.265+/H.265/H.264/H.264+ video compression, up to 3 streams and up to 25/30 fps at 4 MP.
• Built‑in microphone and 1 W speaker for two‑way audio; on‑board microSD storage up to 512 GB.
• PIR presence detection (approx. 8 m range) plus standard network interfaces (RJ45 10/100 Mbps). Power via PoE (802.3af) or 12 VDC.

Installation & use: Compact cube form factor for desks, ceilings or shelves. Designed for indoor/covered use. Typical power consumption ≤7 W. Follow manufacturer installation instructions and local electrical regulations when wiring (BS 7671 in the UK).

Compliance & datasheets: Manufacturer datasheet and user manual should be consulted for regulatory markings (CE/UKCA) and full safety information — INSUFFICIENT DATA in the provided record to confirm specific certification markings.

Note: Specifications such as PIR range, IR distance and minimum illumination are variant‑dependent; refer to the official Hikvision datasheet for full technical limits and installation diagrams.
