Overview: The Hikvision DS-2CD2047G3-LI2UY/SL is a 4 MP ColorVu Smart Hybrid Light fixed mini‑bullet network camera with integrated microphone, speaker (two‑way audio and audible warning), and programmable strobe/white‑light deterrent. It delivers full‑colour daytime and low‑light imaging using a 1/1.8" progressive scan CMOS sensor and an F1.0 super‑aperture lens. The camera supports deep‑learning analytics, H.265/H.264 codecs, PoE+ or 12 VDC power and a rugged IP67 / NEMA 4X anti‑corrosion housing for outdoor use.

• Resolution: 4 MP (2688 × 1520), up to 25/30 fps.
• Low‑light: F1.0 super‑aperture lens with ColorVu Smart Hybrid Light (white + IR), colour imaging to 0.0001 Lux; supplement light up to 40 m.
• Analytics: Deep‑learning: person/vehicle classification, face capture, perimeter protection (line crossing, intrusion, region entrance/exit), target‑type alarm.
• Active deterrence: Built‑in speaker (up to 2 W) for two‑way audio and audible warning plus strobe/white‑light output.
• Connectivity & storage: PoE+ (IEEE 802.3at) or 12 VDC, microSD up to 512 GB, ONVIF S/G/T, NAS (NFS/SMB), ANR.
• Build: Metal body, IP67 and NEMA 4X rated for outdoor/harsh environments; operating −30 °C to 60 °C.

Use cases: Suitable for commercial and residential perimeter monitoring, retail and car‑park surveillance where active deterrence and clear colour imaging at night are required. Equally applicable to contractor installations requiring PoE+ supply and deep‑learning analytics for reduced false alarms.

Installation & compliance: Typical installation requires a PoE+ switch or 12 VDC supply sized to the camera’s power draw. Check the product label and local regulations for CE/UKCA and end‑user compliance. For safety and warranty, install by a qualified technician and follow Hikvision’s installation guide and wiring best practice.
