The idea of modet controls through userspace is:
The first of all need select region number (0..3) (it value stores)
And then config thresolds (pixel,motion,trigger) for that region.
Also it`s available setup regions controls (each of 16x16 rects of the frame,
where detection will be approve).
In user space need only add/delete or clear some rect (set top,left,width,height)
and system automaticaly set up each 16x16 rects for that.
Clear buttom/menu clears all modet region for detection. (idle work)
