From the Property Sheet view, you can manually add and remove these cameras by changing their ORDs. However, they are set for you automatically when you drag a camera to a Surveillance Viewer grid. If no cameras are available, list is empty. |
| Aspect Ratio | drop-down list (defaults to the camera’s aspect ratio) | Defines the image aspect ratio. When you drag to re-size the view, the driver preserves this aspect ratio. |
