The Dahua DHI-TPC-DF1241-S2 is a hybrid thermal network mini turret camera designed for precise surveillance using dual-spectrum imaging. It combines thermal and visible light technologies with advanced AI capabilities, making it ideal for perimeter protection, heat monitoring, and small-area surveillance.

Key Features:

  • Thermal Resolution: 256 × 192 pixels with Vanadium Oxide uncooled focal plane sensor for accurate thermal imaging.

  • Lens Size: 2mm Optical, 2mm Thermal.

  • High Sensitivity: Thermal sensitivity (NETD) of <40 mK ensures detailed detection.

  • Spectral Range: Operates in the 8–14 µm range for effective thermal monitoring.

  • Visible Camera: Equipped with a 4 MP progressive scan CMOS sensor for clear visual imaging.

  • Dual-Spectrum Fusion: Combines thermal and visible images for comprehensive monitoring.

  • AI Analytics: Supports features like tripwire, intrusion detection, human/vehicle classification, smoking detection, and heat alarms.

  • Environmental Protection: IP67-rated for dust and water resistance, suitable for outdoor use.
