23 +== Monitoring system ==

25 +we implemented a monitoring system for the important beamline cameras in FLASH1 and FLASH2.
26 +
27 +the camera check overview shows a red indicator if the camera is off OR the actual values are different from the saved reference values. Clicking on the red symbol in the camera check one can get to the overview of the parameters. Here a red dot indicates which parameter is different from the reference setting. e.g. if ROI settings have been changed also the reference settings have to be changed accordingly if they are now the new reference !!

29 +The warning is also shown inn the according control panels for the cameras.
