Privacy Zones | Masked areas of the camera dome's viewing area. These masks prevent operators of the |
| surveillance system from viewing these designated zones. Each Privacy Zone has four |
| sides, and the zones may overlap to form irregular shapes. The Privacy Zones move in |
| relation to the dome 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 camera dome. |
Quick Set Menu | A special menu that provides access to commonly used features and functions when |
| used with compatible controllers. This allows for changing or activating features |
| without starting the dome configuration menu. |
Random Scan | An automated scan that pans randomly between the left and right scan limits, starting at |
| any point between the scan limits. See Smooth Scan and Stepped Scan. |
Scan | Automated surveillance between predefined scan limits. Three types of scans are |
| available: smooth scan, stepped scan, and random scan. See Smooth Scan, Stepped |
| Scan, and Random Scan. |
Scan Limits | Two points around the dome’s pan axis, which define a surveillance area. |
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 for NTSC, and 2/3 to 1/50 for PAL. The |
| default setting is 1/4 for NTSC and 1/3 for PAL. |
Smooth Scan | An automated scan that slowly pans between the left and right scan limits, starting at |
| the left scan limit. When the right scan limit is reached, the scan reverses. See Stepped |
| Scan and Random Scan. |
Stepped Scan | An automated scan that pans slowly pausing momentarily every 10° between the left |
| and right scan limits. Once the right scan limit is reached, the scan reverses. See |
| |
Virtual Views | Similar to Preset. However, virtual views store the pan, tilt, zoom, focus, and iris |
| settings within the controller, not the dome. Virtual Views cannot be used for the Home |
| |
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. |
Zoom | To adjust the magnification of the camera lens to make an object appear closer (larger) |
| or farther away (smaller). See also Zoom stop factors. |
Zoom stop | Defines how the zoom function is partitioned. The first zoom stop setting may be 22X |
factors | or 33X. The default first zoom stop setting is 33X. The maximum zoom stop setting |
| may be 44, 66, 88, 110, 132, 154, 176, 198, 220, or 242X. The default maximum zoom |
| stop setting is 88X. |
