3.2 Operating principle of the device
The V200/V300 safety camera system comprises a camera as well as a reflective tape
with which the contour to be monitored is defined.
The camera monitors the area bounded by its field of view and the reflective tape – the
protective field – for interruptions. If the V200/V300 detects an interruption in the shape
of the protective field, the camera shuts down its safe outputs.
