Motion detection commands
The user could configure the motion detection in max up to 4 specific areas
(depends on models). Each area could have its own name and its own threshold
setting. Once the moving indicators exceed the user-configured threshold, then it
should have a motion detection event.
Here's the definition of the detected area coordinate.
For some reasons, the client S/W might need to backward support the motion
detection CGI and padding data within the old models of camera. Please refer the
appendix
section to get the details..
The home (0, 0) position is located at the left-top corner. The whole scale is for
640x480 resolution. So the horizontal position, x, will be expressed as an integer
value from 0 to 639 and ascend from left to right. The vertical position, y, will be
expressed as an integer value from 0 to 479 and ascend from top to bottom.

The configured area coordinate:
The left-top corner is the start position. The right-bottom corner is the stop
position.

Whatever the current streaming resolution is, the replied coordinate always maps
to the 640x480 scale.
