At this year‘s Security event, Fujifilm Europe is showing their Fujinon DV2.2x4.1SR4A Varifocal lens for security applications.
This lens provides improved optical performance with a definition of 4K for use with high-definition CCTV cameras. In combination with high resolution 6 Megapixel cameras (1/1.8“), the lens delivers sharp, detailed images and high resolution right up to the edge of the image. With a focal length range of 4.1mm to 9mm (2.2x) and a maximum aperture of F1.6, it will provide a large choice of options in selection of the image frame for many applications.
Thanks to day/night technology, it is also usable around the clock, both within and outside buildings.
