Description
Lenses in the varifocal category offer a selection of imager format optics in various focal length ranges. These ranges include ultra-wide to wide angle, wide
to medium angle, and medium-wide to full telephoto.
The 1/2-inch imager format lenses are available in both C- and CS-type mounts, depending on the model used. A 5-mm spacer (commonly referred to as a
C/CS-mount adapter and available from Pelco as the PCMA40 lens adapter) may be used to make a C-type lens compatible with a CS-type camera.
However, CS-type lenses are not compatible with C-mount cameras. The CS lenses require fewer glass elements to focus at a shorter distance, while not
affecting picture quality. The 1/3-inch imager format lenses come with a CS-type mount only.
All varifocal lenses feature high-resolution power in a compact body.
The VA Series lens has a manual iris, manual focus, and manual zoom. The VD Series lens has a direct-drive auto iris, manual focus, and manual zoom, plus
two of the VD Series are also infrared lenses for day/night camera use but which also provide better optical focus for all cameras. The VDIR Series infrared
lenses are designed primarily for use on color cameras with a moving filter arrangement or on black and white cameras. The VV Series lens has a video-
drive auto iris. Both the VD and VV Series have an industry-standard, square, four-pin connector that plugs directly into the camera receptacle. In addition,
all auto iris lenses include a spot filter.

Installation
Remove the dust cover from the lens. Remove any dust with a soft brush or clean compressed air.
Install the lens by carefully threading it clockwise on the mount of the CCTV camera until fully seated. If the lens has a coupling ring, tighten it against the
camera. Use a C/CS-mount adapter if attaching a C-type lens to a CS-type camera. The PMCA40 adapter is available from Pelco.
If your lens has a direct- or video-drive auto iris, plug the electrical connector directly into the camera’s DC-drive or video-drive socket, whichever applies.
Follow the camera operating instructions for iris and focus adjustments.
