Syntax
object.MotionDetectSet( iTolerance, bPreview, [optional lFrequency], [optional lTriggerFrames],[optional iSpacing], [optional lDetectFromX], [optional lDetectFromY], [optional lDetectToX], [optional lDetectToY] )

Parameters
iTolerance = int, pixel RGB color change before detection is triggered.
bPreview = boolean, show motion detection live, fit to control, (retains aspect ratio of source).
lFrequency = int, miliseconds between frames
lTriggerFrames = long, number of consecutive frames detecting motion before event MotionDetected triggers.
iSpacing = int, pixels spacing 3 minimum
lDetectFromX = long, X coordinate to start detection area in pixels, default = 0
lDetectFromY = long, Y coordinate to start detection area in pixels, default = 0
lDetectToX = long, X coordinate to stop detection area in pixels, default entire source width.
lDetectToY = long, Y coordinate to stop detection area in pixels, default entire source height.

Additional Notes
Motion detection requires RGB format,  usually default but can be set with captureDlgFormat if required.

Pictorial view of detection pixel groups,   1   = detection pixel.

0	1	0
1	1	1
0	1	0

Each detection point is grouped from 5 pixels as shown above, All 5 pixels must change value of red, green and blue color values greater than the iTolerance in order to trigger the detection event.

iTolerance can be changed manually at anytime using the MotionDetectTolerance() or MotionDetectLevel() methods.

The pixel groups are spaced a part horizontally and vertically using iSpacing this is to reduce CPU usage.

Frames are checked every iFrequency, this can be set higher to reduce CPU usage.

Partial area or full area detection of source can be set with lDetectFromX, lDetectToX, lDetectFromY, lDetectToY.

Result
Sets motion detection parameters, before MotionDetectStart().
