PROGRAM & OPERATION
This option is used to set the limit of the horizontal view angle so that the trim ring or
ceiling does not obstruct the horizontal image when zooming out (wide angle).
ON
: In some installations it is desirable for the dome camera to be able to see above the
horizon. When this option is chosen, the dome will tilt up over the horizon (About - 5
degrees). When the lens is zoomed out, you can see the ceiling line. But when the lens
is zoomed in, the viewing angle is narrower, and the ceiling line disappears.
Without Bubble
: The tilt range of the camera is limited to see the horizon so the picture
shows part of the ceiling line.
With Bubble
: The tilt range of the camera is limited to see below the horizon (10
degrees).
AUTO
: The tilt range of the camera is limited automatically according to the zoom ratio
(-5 ~ 10 degrees) when it moves vertically.
