Select a setting and use your keypad’s zoom key to zoom in and out. Choices range from 1x to 12x
(default).
Lift. Lift is a camera feature that optimizes the video’s color over long runs of coaxial cable. Use the
joystick to adjust the lift. Right increases and left decreases the lift. Choices range from 0 to 7. Default
is 0.
Gain. Gain is a feature that optimizes the video’s brightness over long runs of coaxial cable. Gain
increases the video signal’s amplitude to increase the brightness of darkened video and to reduce the
noise of weakened video. Use the joystick to adjust the gain. Up increases and down decreases the
gain. Choices range from 0 to 31. Default is 0.
Zoom speed. Zoom speed is a feature that sets the rate at which the zoom motors operate. There are three
fixed settings and one variable setting. If your keypad provides variable-speed control for zooming,
you can use the Variable setting and the joystick’s range of motion for operation. Twist the joystick
farther for faster zoom changes and less far for slower zoom changes. Choices are Variable (default),
Slow, Medium, and Fast.
Note: If your keypad does not provide variable-speed control for zooming, then you must select one of the other
settings. The variable setting will not work.
Default preset freeze. Default preset freeze is a global setting that sets a default for image freeze to Off or
On. This setting works in conjunction with the Image freeze feature (see Edit page on page 44), which
you can set to Default, Off, or On for individual presets. Be aware that the Transition feature (Freeze or
Zoom out) must be programmed separately when presets are programmed into macros. See Program
page on page 51. Choices are Off (default) and On.
Tilt up limit. Tilt up limit is a feature that sets a programmable stop for the camera at the highest point
that you want it to tilt up. By default, the pan and tilt limits are off. Programming them turns them on.
If E-flip (see Speeds/Tracking page on page 72) is enabled (checkbox checked), constraints are placed
upon the tilt limits. See Table 8 on page 40 for constraints. To review tilt coordinates, see Coordinates
page on page 29.
Note: The dome prevents any hourglassing behavior by restricting the tilt limit to 90°, when necessary, to
accommodate some pan limits set to less than 180°. To avoid setting tilt limits too tightly, we recommend
that you set the pan limits first, then set the tilt limits.
Tilt down limit. Tilt down limit is a feature that sets a programmable stop for the camera at the lowest
point that you want it to tilt down. By default, the pan and tilt limits are off. Programming them turns
them on.
CAUTION: Lift and gain compensate for long runs of video coaxial cable. Only qualified personnel should adjust
these settings. Incorrect adjustments can impair video quality.
