The Day/Night feature’s Auto setting works only if the Exposure Control feature is set to Auto
or the Return to auto feature is set to On. While other features are controlling the exposure, the
camera cannot use the Day/Night feature automatically. See Table 5 on page 51 for the
interactions between the Day/Night feature’s Auto setting and the settings of the Control and
Return to auto features.
Two conditions can prevent the camera from switching between the color and monochrome
modes according the
Day/Night feature’s Auto setting. One, if you’ve overridden the Control
feature’s Auto setting with manual commands from the keypad. Two, if you’ve called a preset (or
a command containing a preset) that is programmed to override the
Control feature’s Auto setting.
In the second scenario, the camera returns to the Auto setting of the Control feature after you
leave the preset. In the first scenario, you must issue a command to return to the Auto setting
of the
Control feature. Using the iris key on the keypad manually adjusts the camera’s iris
setting or shutter speed, overriding the Auto setting of the Control feature. You must issue a
pan or tilt command from the keypad to leave the manual override and return to the Auto
setting of the
Control feature. While you remain in the manual override, the camera will not
switch between the day and night modes according to the changes in the lighting conditions.
• Manual : Allows you to manually switch the camera between day (color) and night (monochrome)
modes using a command from the controlling device (keypad, ASCII control software, etc.). On a
KTD-405, press and hold the Esc key, and press the Magnify button. On a KTD-404, a key must
be programmed for this function. Contact Technical Support for instructions on how to reprogram
a key. Manual switching between Day and Night is not available on the KTD-400.
• Off : Allows you to disable both the automatic and manual modes. The camera cannot be switched
between the day and night modes. Switching commands from the keypad are ignored. The dome
remains in the mode that it was in when Off was selected.
White balance. White balance is another camera feature that compensates for lighting conditions. It
adjusts the quality of all of the colors in the video by balancing the colors to achieve the truest white
possible for the available lighting conditions (Tungsten, fluorescent, natural). To correctly set the white
balance, focus the camera on a white object. Choices are Auto (default), Indoor, Outdoor, ATW, and
Manual.
• Auto : This mode automatically adjusts the color within the 3000 to 7500 Kelvin color temperature
range.
