Pelco Manual C1456M-D (10/98) 315.2.1 Auto Flip
When the camera tilts downward and goes just beyond the vertical position, the dome
rotates 180 degrees. When the dome rotates (flips), the camera starts moving upward
as long as you continue to hold the joystick in the down position. Once you let go of the
joystick after the dome rotates, joystick control returns to normal operation. The auto-flip
feature is useful for following a person who passes directly beneath the camera.
You can disable this feature in the auto flip programming menu. Refer to Section
5.11.19, AUTO FLIP.
5.2.2 Scan Speed
Scan speed is adjustable from 1 to 40 degrees per second through the program-
ming menu.

The Spectra® (Version 3.0) dome can magnify an object up to 96 times. The dome
has 12X of optical zoom and 8X of electronic (digital) zoom for a total of 96X zoom.
The amount of zoom can be set for 12X, 24X, 48X, or 96X. Software controls the
amount of zoom. Refer to Section 5.11.3, ZOOM LIMIT, to program the zoom limits.

the button until the desired picture is obtained.
48X or 96X Zoom

5.4 PRESET FUNCTIONS
The Spectra® (Version 3.0) dome is capable of going to 64 preset locations, each
with a 20-character label. The presets are numbered 1-32 and 35-66.
Refer to the documentation for your control system for programming presets.
When a preset operation is performed, the amount of error in moving to the pan and
tilt position a is 1/2 degree. If you command the dome to go to an undefined preset,
erratic operation may result.
Presets 33 and 34 are fixed commands, meaning that you cannot program them.
Preset 33 is the “flip” command, which will pan the dome drive 180 degrees from
the position it is at. Preset 34 is the “pan zero” command, which will direct the dome
drive to the factory-determined zero reference point.
The following presets are reserved for special functions:
