Key installation points

With the IV2 Series, clear images can be captured automatically even for glossy CDs, and the detection area can be set easily just by outlining it.
Also, setting the tracking angle stabilizes detection because tracking is performed even if the rotation direction is not fixed. Furthermore, shapes and colors on the printed surfaces of the CDs can also be detected, so anyone can easily add and change settings for product type changes.
