3.4 Operating principle of the reading system
The camera system is an intelligent sensor system for the automatic and non-contact
identification and decoding of 1D/2D codes. In principle, the codes can be identified on
any side of moving objects in a conveyor system.
In the case of single-side reading, the codes are identified by a camera from above,
below, or from the side. To facilitate the mounting and alignment of the camera system,
the camera image is taken via a deflector mirror.
The camera system is operated in conjunction with a controller unit, by means of which
the read results are output to the data interfaces.

External sensors provide information about the read cycle, the object distance, and the
position of the object on the conveyor.
