HD-SDI CAMERA

to 8 patterns may be programmed for the dome camera.
PRESET
Programmed video scene, based on a specific pan, tilt, zoom, and focus settings. Up to
240 presets may be programmed for the dome camera.
PRIVACY ZONES
Privacy zones are areas that are masked. These masks prevent operators of the
surveillance system from viewing these designated zones. The Privacy Zones move in
relation to the dome camera’s pan/tilt position. In addition, the apparent size of the
Privacy Zone adjusts automatically as the lens zooms in or out. Up to eight Privacy
Zones may be established for a dome camera.
SHUTTER LIMIT
Setting used to define the maximum exposure time for the Open Shutter setting. The
values for the setting range from 1/2 to 1/60. The default setting is 1/4.
WHITE BALANCE
Adjustments in the color hue (red and blue) gains for a camera so that true white
appears white in the image. It is normally compensated for by the automatic gain control.
In some lighting conditions, you may need to manually adjust the red and blue settings
for optimal viewing. When Automatic White Balance is enabled, the camera measures
the image and automatically adjusts the red and blue settings to balance white. When
Automatic White Balance is disabled, the camera uses the values set for the red and
blue settings to balance white.
