Main advantage:

The camera capture the shape of your work pieces which are randomly place in the marking area and precisely do the marking irregardless of the position and orientation of the work pieces. The camera is  able to mark work pieces of different shapes by first capturing the various shapes before the marking process. With the camera capture function, inaccurate marking due to inaccurate positioning of the work pieces by operators are 

eliminated. Able to resume the original marking position, which allows for accurate

 repeated markings which greatly reduce the chance of spoiled or sub standard 

marking which in turn reduce wastage and the time to repair. Camera capture marking is at least 10 times faster than positioning of the work pieces by the operator. Highly recommended for marking large quantities of work pieces.
