Initial Set Up of: Views,
Maps, Cameras
Introduction to Map/Camera Set Up
"Views" and "Maps" must be set up before
visual monitoring and/or status & control tasks
can be performed.
Notice: It is extremely useful to familiarize yourself with
the operation of this feature, and plan how you want
your views and maps set up before you begin.
Grid view
: Due to its visual nature, this feature uses
'forms' view only.
Permissions: Setting up maps, cameras, and 'views'
requires an operator with permission to "Configure
Visual Director". This permission is also required to
change camera image quality/sizing (right-click menu).
Supported Map File Formats
Map images to be used with this feature must
have been saved in one of these file-formats:
 Vector/Drawing Formats: WMF, EMF
 Bitmap/Photo Formats: BMP, JPG
Note: Scalable graphics work best (EMF, WMF), and
are recommended--especially for more detailed maps.
