cursor over to the area showing video stream, at which point it will appear as a
drawing pen. To draw the rectangle that will mark the area for detection, click and drag
your cursor to draw a red rectangle.
For a better experience, make sure that the height of your detection area is no
taller than 10 times the Maximum Plate Size height, and that the width of your
detection area is no wider than 10 times the Maximum Plate Size width.
6. If the area you want to mark does not fit the form of a rectangle, you may also choose
to draw a polygon by selecting the icon on the upper right corner of your Live
View Display area. To draw the lines for the sides of your polygon, click your cursor to
mark the endpoints of each line. Double-click on the final endpoint of the final line to
confirm and highlight the polygon in light blue, as shown in the illustration below. Make
sure your lines connect (a minimum of 3 lines) to form a closed shape.
