This system is an advancement of our single camera system. The four camera system still uses our unique part separation and lighting technique but has the added advantage of being able to see the entire wall on the inside of each closure. It has a single camera inspecting from the top (identical to the single camera system) and three cameras located 120 degrees to each other looking at the inside wall of the closure. These side cameras have proven to be successful at inspecting for incorrectly seated liners and pull-tabs.
