Greater Flexibility in Security and Surveillance

Tamron Europe GmbH announced the new 1/3 20100mm F/1.6 Aspherical Vari-Focal which covers the telephoto range that is normally covered only by zooms, yet the zoom function that makes the lens more costly is not utilized in many installations. The new Tamron Vari-Focal is an efficient replacement from the point of view of both cost and size. With a focal-length range that covers everything from moderate to super-long telephoto, a fast F/1.6 aperture that insures bright imaging even in dimly illuminated areas, and aspherical optics that provide outstanding image quality in a compact, lightweight package, the new 20-100mm F/1.6 for 1/3-inch CCD cameras is a significant new entry in the CCTV surveillance and security industry. Until now, security systems distributors, installers, and end users often use expensive motorized zoom lenses just to get the reach they needed. Or they had to use shorter-focal-length lenses mounted on poles, a system that means greater installation costs for trenching and wiring, less convenient maintenance, and susceptibility to image-degrading vibration. The Tamron 20100mm F/1.6 eliminates all these problems, and provides far greater flexibility in security and surveillance installations than any previous lens in its class. Also, being free to place the camera at a greater distance minimizes the need to conceal it in sensitive applications, and allows the camera to be mounted on a wall opposite the target area, giving a clear, direct shot of faces and other essential details. This latter capability is especially important at locations ranging from airports to casinos, where excessive camera-to-subject angles may prevent the camera from capturing critical information. The 20100mm Tamron F/1.6 Aspherical Vari-Focal covers an angle of 13.6˚ x 10.2˚ (horizontal x vertical) at the 20mm setting, and an amazing 2.8˚ x2.1˚ at the 100mm setting, the latter being roughly equal to a 5-foot area at 100 feet on a 1/3-inch CCD.
