Positioning the camera and the camera arm
The Sentry+[HD] features a flexible camera head and a rotatable camera
arm. The camera head can be swivelled around a horizontal and a
vertical axis. The camera arm can be rotated around the base. Point the
camera to read a document nearby. When you want to look in the
distance (for example at a blackboard) or at yourself, you need to remove
the close-up lens and turn the camera in a horizontal position. By
loosening the screw lock at the end of the camera arm, you can adjust the
height of the camera (this will affect the magnification range).
Close-up and distance viewing
The position of the camera can be adjusted for desktop or distance
viewing. To view objects within 55 cm, position the close-up lens in front
of the camera unit. To view objects at a more distant proximity, position
the close-up lens away from the camera. To prevent losing the close-up
lens, attach the lens to the top side of the camera head.
Use the near lens with the flattened edgings for the position below and
use the round lens for the upper position.
Use of the built-in object lighting
The double LED-lighting is built in to the camera arm
for use in poorly-lit environments. The lighting can be
switched on and off by pushing the zoom button in the
following order: “step 1/ step 2/ Off”.
