The Hikvision DS-2CE70DF3T-PFS (2.8mm) is a 2 MP ColorVu indoor fixed turret camera designed for high-quality surveillance in indoor environments such as offices, retail shops, corridors, and residential areas. It features a 2-megapixel CMOS sensor that delivers clear Full HD video with a resolution of 1920 × 1080, ensuring detailed and reliable monitoring. The 2.8 mm fixed lens provides a wide viewing angle, making it suitable for monitoring medium-sized indoor spaces with effective coverage.  One of the key technologies in this camera is ColorVu imaging, which enables 24/7 full-color video, even in extremely low-light conditions. This is achieved through its F1.0 large-aperture lens and integrated white light illumination, which can provide visible lighting up to 20 meters for clear nighttime monitoring. The camera also supports 130 dB true Wide Dynamic Range (WDR), allowing it to produce balanced images in scenes with strong lighting contrast, such as entrances or windows.  The DS-2CE70DF3T-PFS includes a built-in microphone with audio over coaxial cable, enabling simultaneous video and audio recording for enhanced security monitoring. It also supports four switchable signal formats (TVI, AHD, CVI, and CVBS), ensuring compatibility with a wide range of DVR systems.  With advanced image processing features such as 3D digital noise reduction and smart lighting control, this camera provides stable and clear footage in different lighting environments. Its compact turret design allows flexible installation and positioning, making it a reliable solution for modern analog surveillance systems
