Hikvision DS-2CD2347G2-LU 4 MP ColorVu Fixed Turret Network Camera

Capture clear, full-color security footage around the clock with a 4 MP ColorVu turret camera engineered for dependable indoor and outdoor surveillance. Its F1.0 super-aperture lens, highly sensitive 1/1.8-inch sensor, 130 dB WDR and up-to-30-meter white light help preserve useful visual details in darkness and difficult backlighting. Deep-learning-based human and vehicle classification helps users focus on meaningful activity, while the DS-2CD2347G2-LU version adds a built-in microphone for real-time audio security.

Key Features

  • 4 MP resolution: Records at up to 2688 × 1520 for detailed security footage.
  • 24/7 ColorVu imaging: Produces vivid, full-color images in extremely low-light environments.
  • F1.0 super-aperture lens: Collects more available light to create brighter nighttime images.

Ideal Applications and Common Uses

  • Home entrances, driveways, patios and side yards where full-color nighttime details are important.
  • Retail stores, offices and small businesses needing clear 4 MP monitoring.
  • Building entrances, reception areas and customer-facing spaces.
  • Parking areas and access points where human and vehicle classification can help reduce irrelevant alerts.
  • Warehouses, corridors and loading areas requiring perimeter-related analytics.
  • Indoor or outdoor areas exposed to rain and dust within the camera's IP67 and operating-temperature limits.
  • Locations requiring visual verification with recorded ambient audio when using the DS-2CD2347G2-LU version.
  • PoE installations where network data and electrical power need to travel through a single Ethernet cable.

Environmental Placement Note

This model has no specific anti-corrosion protection. Although it carries an IP67 water- and dust-resistance rating, the datasheet does not classify it for coastlines, docks, chemical plants or other environments requiring specialized anti-corrosion protection.
