Hikvision DS-2CD2187G2H-LI(SU) — 8 MP ColorVu Smart Hybrid Light Mini Dome IP Camera

If you’re tired of “good enough” footage that turns useless the moment lighting gets tricky, this 8 MP ColorVu mini dome is built to fix that. You get sharp 4K detail, smart hybrid lighting (IR + white light) for long-range visibility, and deep-learning human/vehicle classification to help reduce noise and wasted time. The -SU variant adds a built-in mic, so you can capture real-time audio where it’s permitted—giving you clearer context when something happens. :contentReference[oaicite:0]{index=0}

Key Features

  • 8 MP (3840 × 2160) imaging — clearer evidence-quality video so faces, actions, and key details don’t blur together. :contentReference[oaicite:1]{index=1}
  • Smart Hybrid Light (IR + White Light) up to 30 m — keeps scenes visible after dark without guessing what’s happening in the shadows. :contentReference[oaicite:2]{index=2}
  • 130 dB WDR — helps balance harsh backlight (like bright doors/windows) so subjects don’t become silhouettes. :contentReference[oaicite:3]{index=3}
  • H.265+ compression — reduces bandwidth and storage needs while maintaining strong image quality. :contentReference[oaicite:4]{index=4}
  • Human & vehicle classification (deep learning) — helps you focus on what matters instead of constant false triggers. :contentReference[oaicite:5]{index=5}
  • -SU built-in microphone — adds real-time audio context (where allowed) for better incident understanding. :contentReference[oaicite:6]{index=6}
  • IP67 + IK10 — built for real-world installs: weather resistance plus vandal resistance. :contentReference[oaicite:7]{index=7}

Ideal Applications / Common Uses

  • Entrances & front doors — 130 dB WDR helps when people walk in from bright outdoor light. :contentReference[oaicite:8]{index=8}
  • Retail floors & checkout lanes — 8 MP detail helps capture critical activity and reduces “we can’t see it” moments. :contentReference[oaicite:9]{index=9}
  • Warehouses & back-of-house areas — Smart Hybrid Light supports visibility after hours up to 30 m. :contentReference[oaicite:10]{index=10}
  • Parking lots, drive lanes, and loading areas — deep learning human/vehicle classification helps keep alerts more relevant. :contentReference[oaicite:11]{index=11}
  • Schools, offices, and multi-tenant lobbies — IK10 vandal resistance + IP67 weather resistance fits high-traffic installs. :contentReference[oaicite:12]{index=12}

Note on environment: the datasheet states this model has NO SPECIFIC PROTECTION for anti-corrosion, so it’s best suited to environments where no special anti-corrosion protection is required (rather than harsh coastal/chemical locations). :contentReference[oaicite:13]{index=13}
