Setting the WideSHOT Lens on the BaseSTATION
Image: 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-Megapixels 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
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, or so, on the innermost
ring, adjust the ring to either the wide (W) or tele (T) direction. The focus ring will need to be adjusted as the
zoom is changed. Experiment with the zoom range to fit the application and room. A full 82.2° may be too
wide in some cases and tailoring the zoom to 58° to 60° may fit the room better. After setting the control,
tighten the knurled zoom 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. Do not tighten the focus knob screw. The outmost focus ring needs to be able to move freely. Set the
focus ring to the approximate position and carefully slide the Focus Knob back on, making sure to line up one
of the 4-slots on the inner focus ring with the focus screw.
