The Hikvision DS-2TD1228-3/QA Thermal & Optical Bi-Spectrum Network Turret Camera integrates thermal and optical imaging to enhance surveillance capabilities. It features a 256 × 192 resolution thermal sensor with a 12 μm pixel pitch, offering a Noise Equivalent Temperature Difference (NETD) of less than 40 mK at 25°C, F1.0. The optical module boasts a 2688 × 1520 resolution, 4.3 mm focal length, and an f/1.6 aperture, ensuring clear images even in low-light conditions. Advanced image processing technologies, including linear, histogram, self-adaptive thermal Automatic Gain Control (AGC) mode, Digital Detail Enhancement (DDE), and 3D Digital Noise Reduction (DNR), further improve image clarity.
Designed for versatile applications, this camera supports video content analysis with vehicle and human classification, enhancing perimeter protection. It also offers temperature exception alarms for early fire detection, with a measurement range from -20°C to 150°C and an accuracy of ±8°C. Additional features include a high-quality detector with a 10-year warranty, smoke detection algorithms, and a sun-reflection filter to maintain image quality under varying lighting conditions. The DS-2TD1228-3/QA is suitable for environments such as villas, communities, parking lots, warehouses, construction sites, and manufacturing workshops.
