11.1.2 The Camera menu
The camera menu provides control of a number of advanced features of the
camera, and access to settings that affect the camera's response to unusual
lighting conditions.
White Balance The White Balance menu item controls how the camera adjusts its colour output
under different types of light source. You can choose between two pre-set
configurations (indoor, outdoor), automatic mode, auto tracing mode, one push
mode that can be automatically re-adjusted only at the request of the user and
manual mode where red and blue gain can be adjusted separately by the user.
NOTE
When in One Push mode, use Iris Open to perform a one push.
Backlight This setting provides backlight compensation for situations where the
background is more brightly lit than the subject
Exposure The EXP Priority setting determines which aspect of control has priority for the
camera’s automatic exposure setting. Choosing a mode other than auto will
allow you adjust the operation of that mode. The Slow Shutter setting controls
whether slow shutter operation will switch in automatically before the Night time
mode is activated.
NOTE
Automatic Slow Shutter is only available when the exposure
priority is set to Full Auto.
Special menu
Digital zoom When digital zoom is tuned ON and the maximum optical zoom range is
reached, digital zoom enlarges the centre of the subject by expanding the image
in both the horizontal and vertical directions.
Day/Night mode The IR-cut filter can be set to engage and disengage automatically as light
levels change, or manually when the Lamps key is pressed.
Auto Flip The Auto Flip function allows continuous tracking of a target moving under the
Dome without the need for the operator to release the joystick.
Video gain If very long coax cable runs are used, video degradation is possible, and
particularly noticeable as loss of sharp edges. See Video gain > XTU video
gain in Section 10.3: The XTU main menu for details.
RTU gain When an RTU (Remote Termination Unit) is in use this setting allows additional
gain to be set to compensate for Cat5 cable lengths in excess of 150 m.
Reset menu This is also accessible from within the Special menu:
CAMERA MODULE RESET Will reset all camera settings
CLEAR PRESETS Clears all preset positions and text.
CAMERA RESET Will re-calibrate the pan & tilt
functions.
FULL FACTORY RESET Will reset the Dome to factory
settings.
LENS INITIALISE Allows automatic recalibration of the
lens.
Backup Dome unit All the Dome settings such as camera setup, presets, tours, patterns, privacy
zones and text can be backed up to the XTU and restored at a later date if the
Dome is switched with another or replaced.
