Key Features

  • 1/1.2″ Progressive Scan CMOS — Large sensor size supports clearer detail and stronger performance in real-world lighting.
  • 8 MP High-Resolution Imaging — Crisp 4K-class detail (3840 × 2160) for identification and evidence quality.
  • DarkFighter Low-Light Performance — Excellent low-light imaging helps maintain usable video when lighting drops.
  • 42× Optical Zoom + 16× Digital Zoom — Pulls distant subjects close without losing situational awareness.
  • Up to 500 m IR Night View — Expansive night coverage for large perimeters and long roadways.
  • IP67 Water/Dust Resistance + IK10 Vandal Resistance — Built for harsh outdoor environments (excluding glass window).
  • Face Capture (Deep Learning) — Detects, tracks, captures, grades, selects faces in motion and outputs the best face picture.
  • Road Traffic Vehicle Detection — Vehicle detection with license plate number, vehicle model, and vehicle color recognition.
