The following options are provided:

Option Description

This button clears all the current colored grid blocks in the view. You can then use the Pencil

tool to define grid blocks for specific ROIs within the view surface.

NOTE: Change detection does not function unless ROIs are identified by colored

(blue, red or yellow) grid blocks.

This button marks colored grid blocks over the entire window surface, meaning that change

detection will apply to the entire camera view. You can then use the Eraser tool to remove

specific grid blocks.

When the Pencil tool 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 red, blue 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 will erase a small (single

block), medium (4-block) or large (16-block) width of surface blocks per

sweep.

The Block Control selector enables you to define how many blocks of the colored grid arrays

must be simultaneously involved in the change before recording is triggered. For example:

• "1" (the most sensitive setting) indicates that recording should be triggered if a change is

detected in even one block amongst all the defined ROIs.

• "16" (the least sensitive setting) indicates that the change must be simultaneously

detected in at least 16 blocks within the entire view area. The blocks do not have to be

contiguous.

NOTE: The selected maximum cannot exceed the total number of blocks defined

in ROIs.

The Sensitivity Control enables you to adjust the triggering sensitivity (by dragging the slider)

between High (higher detection of changes) to Low (lower detection of changes).

NOTE: In general, a "normal" sensitivity should be selected. The highest

sensitivities may generate false alarms, while the lowest may cause

interesting events to be missed.

The Show Grid button applies a gray planning grid to the parts of the window where no ROIs

(colored grid blocks) are defined. The gray grid is only for purposes of viewing where ROIs

may potentially be defined and does not affect the change-detection process. When selected,

the button changes into a Hide Grid button by which the planning grid can be suppressed,

making only the "active" colored grid blocks visible.
