ViewZ 2MP 20-700mm F3.2 Day&Night Motorized Zoom Lens with C-Mount, DC Auto-Iris

To achieve the full resolution of a megapixel camera, it is essential to use a high quality megapixel lens. Overall image quality is greatly affected by the quality of the optical image directed onto the image sensor. ViewZ Megapixel lenses provide high contrast, brightness and sharpness across the entire image plane. Non-megapixel lenses will not fully display the resolution of megapixel sensor, especially in the corner areas of the image. High-End Motorized Zoom ViewZ high resolution megapixel zooms offer a wide range of manual and motorized versions including our 35X day/night model suited for long range port and border surveillance. The compact and lightweight design allows establishment of compact remote surveillance systems. Many models are available with preset potentiometers. 24 / 7 Surveillance Application There is a growing need for compact, high quality lenses for 24/7 surveillance applications such as parking lots, factory premises and streets. Continuous surveillance is also required for public facilities such as airports, harbors, highways and border patrol, requiring more versatile focal lengths and higher zoom ratios. ViewZ Day/Night (IR) lenses respond to infrared illumination to capture clear, corrected images in all lighting conditions. We offer a lineup of lenses from the standard focal length of 2.8-12 mm to the diverse focal length of 8-80mm featuring ED (Extra-low Dispersion) glass for maximum focus shift correction under IR and excellent daytime performance. Made In Japan All ViewZ lenses are all made in JAPAN and we produce superior quality products in a small-sized manufacturing environment, where we respect craftsmanship. Viewz offers over 180 advanced lens solutions such as Fixed, Vari-Focal and Zoom in both standard and megapixel resolutions for a variety of applications. Each ViewZ lens is backed by our 4-year warranty. DC-Type Auto-Iris An auto-iris lens without an internal circuit to control the iris. All iris control voltages come from a circuit located within the camera to adjust the iris for changing light levels. DC-type lenses are recommended for use in inconsistent lighting conditions (e.g. outdoors). These are sometimes referred to as DD (Direct Drive) lenses. Various Focal Length Focal length is the basic characteristic of a lens and determines how much magnification it provides. The focal length defines the area of the scene that can be viewed with a given sensor size and is expressed in millimeters (mm). ViewZ lenses have many options when it comes to focal length selection to fit your application. C Mount CCTV lenses are available in two different lens mounts. Many of today's cameras can accept either type of lens, but it is important to make sure that camera and lens are compatible and set up properly. C-mount lenses have a flange back distance of 17.526mm vs. 12.5mm for CS-mount lenses. C-mount lenses can be used on CS-mount cameras by utilizing a5mm adapter or adjusting the camera for C-mount lenses.
