Hi Brian,

I suspect your problem is related to these settings,

> Alarm Threshold (0>=?<=255) 1

This basically means how different a pixel has to be from it's predecessor where 0 is black and 255 is white (in brightness terms). A value of 1 will probably mean that virtually every pixel will match causing nearly the whole image to alarm. This may cause it to exceed the Maximum Blobs value. I would change this to 10 or 15 to start with, you may have to increase or reduce it depending on the type of image you have.

> Filter Width (pixels) 10
> Filter Height (pixels) 10

These should be smallish and odd so instead of 10 I would recommend starting with 3 or 5.

Once you have it working I would also start to reduce the maximums from the 100% value you have now but this is up to you and whether you want to eliminate any glitches, bugs on the lens etc etc.

Cheers,

Phil,
