Setting the WideSHOT Lens
Image: WideSHOT Focus Knob Removal
You may ask, “Why would anyone want to remove the focus knob?” The answer is directly correlated with the
quality of this wide-angle HD lens. It is not a plastic “webcam”, but instead it is an exceptional quality glass lens,
rated up to 3-megapixel with a 3.3mm to 10.5mm precision varifocal optical zoom lens with manual iris and
manual focus controls.
Image: Adjusting the HD Varifocal Optical Zoom Lens
After removing the focus knob screw and carefully sliding off the “snug” focus knob, the lens controls are exposed
and available for adjustment. The controls are as follows:
1)
The Optical Zoom Control:
By carefully untightening the knurled screw a half turn on the innermost ring,
adjust the ring to either the wide (W) or tele (T) direction. The focus ring, now without knurled adjustment
screw (screw taken out to remove the focus knob) will need to be adjusted as the zoom is changed.
Experiment with the zoom range to fit the application. A full 82.2° may be too wide in some cases and
tailoring the zoom to 65° to 70° may fit the room better. After setting the control, tighten the knurled screw.
2)
The Manual Iris Control:
After setting the zoom range and focusing on the subject’s at the distance that the
camera will be used, the iris can be adjusted to limit the amount of light that the image sensor receives, which
in turn gives an increased depth of field for focusing on the people in front of the camera. The “O” stands for
open and the “C” stands for closed. Experiment with the iris to achieve the best results for the application.
After setting the control, tighten the knurled screw.
3)
The Focus Control:
The outermost ring is the focus control and can be adjusted to the near (N) or far (F)
side. Set the focus ring to the approximate position and reattach the focus knob with the knurled screw when
finished.
