The window shows the Live view of the selected camera, with colored grid blocks over selected regions
of interest. If no settings were yet defined for this camera, colored grid blocks cover the entire picture,
indicating that the change detection that would trigger alarms applies to the entire camera view area.
You can focus the VMD on security-sensitive objects in the camera space by using the window
functions to vary the coverage of the colored grid blocks. (Only the segments covered by colored grid
blocks are considered for VMD purposes.)
For example, you can focus on windows or doors (as shown in the picture
opposite) to monitor opening/closing events.
The following options are provided:
Option Description
This button clears all the current colored (blue, red or yellow) grid blocks in the view. You can
then use the Pencil tool to define grid blocks for specific ROIs within the view surface.
NOTE: The VMD does not function unless ROIs are identified by colored grid
blocks.
This button marks colored grid blocks over the entire window surface, meaning that VMD will
apply to the entire camera view. You can then use the Eraser tool to remove specific grid
blocks.
When one of the Pencil tools is selected, the cursor becomes a pencil icon.
You can define ROIs by clicking and dragging over the required view area segments, thereby
drawing arrays of blue, red or yellow grid blocks (according to which pencil is selected).
The Tool Size Selector area includes buttons for three pencil sizes. According to
the selected size, the cursor draws a small (single block), medium (4-block) or
large (16-block) width of grid blocks per sweep.
When the Eraser tool is selected, the cursor becomes an eraser icon. You can erase ROI
segments by clicking and dragging over selected grid blocks, thereby erasing them.
The Tool Size Selector area includes buttons for three eraser sizes. According to
the selected size, the cursor erases a small (single block), medium (4-block) or
large (16-block) width of grid blocks per sweep.
