I am trying to create a zone that is only sensitive to a small portion of the screen a peice of paper in my test. No problem I moved the 4 points around the item. My question is what do I need to put for all of the settings on the new zone. I read the manual but it does not make a lot of sense to me.
The below settings is what I need help with...of course I know I can Name the zone what I like and I understand kind of what all of the types are.

Name
Type
Preset
Units
Alarm Colour (Red/Green/Blue) / /
Alarm Check Method
Min/Max Pixel Threshold (0-255)
Filter Width/Height (pixels)
Zone Area
Min/Max Alarmed Area
Min/Max Filtered Area
Min/Max Blob Area
Min/Max Blobs
Overload Frame Ignore Count

A quick rundown

Blob - slower but more accurate as it uses a average for 2+ pixles for referance

Alarmed pixles - fast but less accurate comparison of pixle color change

Preset - unless you doing something extreamely speciles stick with a preset and leave everything else alone.

Alarm Colour (Red/Green/Blue)
Just for you makes no diffrence.
