The Hikvision DS-2TD2628T-7/QA Bi-spectrum Thermography Network Bullet 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. This high-sensitivity sensor enables precise temperature measurements ranging from -20°C to 550°C, with an accuracy of ±2°C, facilitating early fire detection and prevention.
Equipped with advanced video content analysis (VCA) powered by deep learning algorithms, the camera can classify vehicles and humans, providing reliable perimeter protection and security monitoring. Its dual-lens design combines a 6.9 mm thermal lens with a 6.4 mm optical lens, delivering clear images in various lighting conditions. The camera also supports features like smoke detection algorithms and sun-reflection filters, making it suitable for diverse environments such as warehouses, construction sites, and manufacturing workshops.
