Detection area... Dark or light zone?

Just a quick and probably stupid question chaps :slight_smile: Are the dark areas the NON detection areas or is that where it detects movement?
It says to choose area by clicking the grid squares but it seems counter intuitive for that area to be blacked out?
Cheers guys

PS this is excellent software, just what I needed and very easy to setup.

Hi Lee! Thanks for the nice words. A secret, I like it too ;).
The sensing area is the non-masked (transparent) area. The masked/black area is the non-sensing area.
