Target
When positioning the camera in a huddle room or similar area, it will be helpful to know the viewing area of the
camera, based on a fixed target. The viewable area of the camera is called the
linear field of view
or sometimes
referred to as the
image plane
.
The illustration below shows the AT-HDVS-CAM-HDMI pointed at a fixed target.
The following table provides a list of predefined distances, which the camera must be placed from the target, in order
to capture the required Linear Field of View (L). The Angle of View, for the camera, has been set to 60.9° (wide-
angle).
To calculate custom values, refer to
Calculating Specific Values (page 16)
