Every detail at a glance! Using this lens, you capture events in extensive surveillance areas in full width and with outstanding sharpness of detail. The lens is a crucial component for professional employment of mega pixel cameras (like the model TVIP51500 and TVIP51550) and indispensable for exploiting the complete potential of mega pixel technology. It regulates the incidence of light on the imager of the camera and ensures optimal exposure of your mega pixel images. All lenses have a standard connection thread. Significant distinguishing features of the mega pixel lenses are the angle of view (102° - 24° with 1/3'' image sensor 74° - 18° with 1/4" image sensor) and the focal length (of 2.8 to 12 mm variable). The larger the focal length, the narrower the angle of view and the closer you can zoom in on the image section. The aspherical lenses ensure particularly high quality images. The high edge sharpness in comparison to other (mega pixel) lenses prevents reliable loss of sharpness at the edges. Also, with the light yield, the lens impresses with a quality that ensures an unobstructed view right up to the edge of the image. The incidence of light through the aperture adjusts automatically to the respective light conditions thanks to the auto-iris function - a particular advantage e.g. in rooms with sudden incidence of light (portal, entrance area, etc.). Suitable for day/night surveillance: All mega pixel lenses are 100% IR light compatible.The CS mount lenses can be conveniently mounted to any camera. The TVAC65000 lens is recommended for the TVIP51500 and the TVIP51550 cameras.
