A camera system for monitoring the position of a connection cable of a trailer, comprising:

• at least one camera which captures a region which lies behind a motor vehicle and generates captured image data;
• an analysis unit which receives the captured image data from the at least one camera and is configured in such a manner to detect the connection cable and determine a position of the connection cable based upon the captured image data;
• a comparison device which receives the determined position of the connection cable from the analysis unit and is configured in such a manner that the determined position of the connection cable is compared with a secure position of the connection cable;
• and
• a warning device which, based upon the comparison, provides a warning signal if the determined position of the connection cable deviates from the secure position.
