 | Varifocal Lenses |
|
Pelco offers a large selection of varifocal lenses. Lenses are available with adjustable zoom for a large range of focal lengths. Unlike a zoom lens, a varifocal lens does not maintain focus when zoomed. The lens at installation is set for optimum field of view. Pelco Day/Night(D/N) corrected lenses correctly focus visible and infrared(nonvisible) light, solving the problem of "focus shift" for cameras with true day/night capability(switching between color and black-white modes by mechanically removing the camera's IR filter). D/N-corrected lenses should also be considered when using day/night cameras. |

| Motorized Zoom Lenses |
|
All Pelco zoom lenses feature auto iris, motorized zoom and focus lens functions. A motorized zoom lens keeps the viewed object in focus while varying the length of the lens. |

| Accessories - Small-to-Medium Matrix Systems |
|
To operate an auto iris DC lens with video signal output, a lens drive converter can be used with any Pelco camera and DC lens equipped with a standard, four-pin square connector. Enhance the picture quality with level adjustments for AGC (automatic gain control) and brightness. |
