The Hikvision DS-2TD1228T-2/QA is a bi-spectrum thermography turret camera that integrates both thermal and visible light imaging to enhance surveillance capabilities. It features a thermal sensor with a 256 × 192 resolution and a 12 μm VOx uncooled focal plane array (UFPA), offering a noise equivalent temperature difference (NETD) of less than 40 mK at 25°C with an F1.0 aperture. The visible light sensor provides a high-resolution 2688 × 1520 image, both equipped with 2.1 mm and 2.2 mm fixed lenses, respectively. This combination allows for image fusion, overlaying thermal and visible light images to deliver comprehensive surveillance footage.
Designed for advanced security applications, the DS-2TD1228T-2/QA supports intelligent video content analysis (VCA), including vehicle and human classification, as well as temperature exception alarms for fire prevention, capable of detecting temperatures from -20°C to 550°C (-4°F to 1,022°F) with an accuracy of ±2°C or ±2%. It also incorporates a smoke detection algorithm, enhancing its utility in environments where early detection of smoke is crucial. The camera’s robust image processing technologies—such as linear, histogram, self-adaptive thermal automatic gain control (AGC), digital detail enhancement (DDE), and 3D digital noise reduction (DNR)—ensure clear and detailed imagery. Hikvision backs the high-quality detector with a 10-year guarantee, underscoring its durability and reliability in various surveillance scenarios.
