1. If IPC is booted without camera connected (or powered), RCS software shows
   the parameter of a simulated camera. This is very useful for developers,
   but might be confusing for users. Please verify that the CameraModel
   parameter is present and does not read 'SIMCAM ...' (a sensible value may
   look like 'ZYLA5.5B-FO'). If that's not the case, first try to hit the
   'Reset Camera Controller' button, which resets the IPC, then wait at least
   two minutes (look at 'Status' parameter for the countdown).
   If this still does not help, try power-cycling the camera itself (and
   reboot the IPC again).

2. If frame rate is lower than expected during DAQ acquisition, please
   verify that DAQ output channel 'hostname' is configured with the IP
   of the control host ethernet i/f meant to be used for DAQ connection

3. There might be some case when the camera gets to a state where a power
   cycling is needed anyway.

4. Invalid parameter settings: the Karabo devices do not prevent the user
   from entering settings that  might be refused from the hardware.
   Such values are overwritten by polling.

5. [For controls colleagues only] Lots of useful information can
   be gathered by setting logger level to 'DEBUG' and looking at server
   output e.g. by using karabo-xterm
