Classifying Preset Camera Positions

A camera with pan/tilt/zoom is placed within the hutch. The camera provides the capability to move to preset positions. It does not have the capability of moving to a position that would provide a view to something that is restricted (e.g. keyboard or monitor). The camera itself is small and unable to hurt anyone during its movement. Requesting a move of the camera would not affect other users of the system or interrupt data collection.

In Blu-Ice the pan/tilt/zoom motors are configured with a 'Passively Accessible' permission for both Staff and Scientists as shown in Table 13. Table 14 shows the capabilities that a user has while issuing commands to this unrestricted device.
