Cropping and Displaying Part of an Image
(Digital PTZ)
You can use the Digital PTZ panel to crop and display
part of a camera image in the image display area. It is
also possible to use a preset or home position registered
to the camera.
 Digital PTZ
Digital PTZ is a function that facilitates simple panning,
tilting, and zooming without changing the camera lens
position that was adjusted at the time of installation by
transmitting just part of the camera effective pixel area
(1920 x 1080) from the camera to the viewer.
Note
For details on how this function differs from Viewer PTZ, see
p. 138.
