Overview
The DS-2CD2347G3-LI2UY is a 4MP fixed‑turret IP camera with ColourVu 3.0 continuous full‑colour imaging and a smart hybrid illuminator (integrated white light + IR). With a large 1/1.8" progressive CMOS sensor and F1.0 lens, the camera delivers excellent low‑light performance and AI‑based person/vehicle classification for reduced false alarms. Ideal for perimeter, retail and general indoor/outdoor surveillance where night‑time colour detail and accurate target filtering are required.

• Key benefits: 24/7 full‑colour imaging, AI person/vehicle detection, smart hybrid lighting up to ~30 m, built‑in dual‑microphone audio, PoE for simple installation.
• Use cases: Perimeter security, retail loss prevention, car parks, building exteriors, and general-purpose CCTV deployments requiring colour at night and AI analytics.
