The default grid size is 3x3, and I understand how the grid can be used to exclude/include specific areas of the image for motion detection, but what I'm not clear about is if the grid size (number of columns and rows) has any affect at all on detection if I'm not using exclusion/inclusion. I see a good explanation of how to change the grid size, but not for why I might want to.In other words, if I'm using the entire image area for motion detection, does the grid size itself have any impact on detection? If all other settings are the same, does a 3x3 grid behave any differently at all from a 6x6 or 9x9 grid? Is there any reason to not use a 1x1 grid? Why default to 3x3?
Is there any significant performance penalty for using larger grids? I'm guessing that there's more computational latency as the number of cells increases?
I've been trying to find a threshold where it is sensitive enough to trigger reliably yet not keep firing once it's been triggered.
