Setting used to improve the quality of video obtained in extreme low-light situations. When the Low Shutter setting is
enabled, low-light information is collected over multiple fields based on the Shutter Limit setting. As a result, video may
appear blurred or choppy in extreme low-light situations. This setting does not effect camera operation in normal lighting
situations. See also Automatic Gain Control (AGC).
PATTERN
A series of pan, tilt, zoom and focus movements from a single programmable dome. Up to 6 patterns may be programmed
for the dome camera. (Dependant upon model).
PRESET - PRESHOT
Programmed video scene, based on a specific pan, tilt, zoom, and focus settings. Up to 128 presets may be programmed for
the dome camera. (Dependant upon model).
PRIVACY ZONES
Masked areas of the dome camera's viewing area. 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 6 Privacy Zones may be established for a
dome camera. (Dependant upon model).
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.
VECTOR SCAN
Move from start point to end point including tilt and zoom simultaneously and linearly.
WDR
Wide Dynamic Range Technology uses two shutter speeds in alternative video fields-high and normal- every 60th (NTSC)
or 50
th
(PAL) of a second and combines two fields into one progressive scan frame. It allows every detail to be captured
accurately even if one portion of an image is more illuminated than the other. Whether at the high shutter speed or normal
shutter speed, the progressive scan CCD provides a horizontal resolution of 470 lines. As a result, combined fields yield a
frame of high-quality images.
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.
