Revo REHVDPTZ22-1 INSTRUCTION MANUAL - Manual (Page 82)

North Position
User-definable setting that may correspond to magnetic north or some well-known landmark.
Used to approximate the camera dome's pointing direction when Direction Indicators are enabled.
Slow Shutter
Setting used to improve the quality of video obtained in extreme low-light situations. When the
Slow 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.
Pattern
A series of pan, tilt, zoom and focus movements from a single programmable dome. Up to 4
Patterns may be programmed for the dome camera.
Preset
Programmed video scene, based on a specific pan, tilt, zoom, and focus settings. Up to 120
Presets may be programmed for the dome camera.
Privacy Zone
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 4 Privacy Zones may be established for a dome
camera.
Vector Scan
Move from start point to end point including tilt and zoom simultaneously and linearly.
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.
