1. 
   Log in to the Raspberry Pi using any account available (default user: pi password: raspberry)
   
   • 
     To view the list of devices enter ‘uvcdynctrl –l’ this should display a list of devices including the camera.
     

• 
  To view the list of available actions enter ‘uvcdynctrl –c’, this will show a list of controls for the device such as zoom, brightness, and contract.
  

• 
  To get the current value of any control enter ‘uvcdynctrl –g control’ where control is the value the user wishes to obtain such as the contrast.
  

• 
  To set a value for any of the controls enter ‘uvcdynctrl –s control value’ for example ‘uvcdynctrl -s hue 0’ to set the Hue value to 0.
  

• 
  To list the available frame formats enter ‘uvcdynctrl –f’, this will give a list of the available frame sizes, frame rates and pixel formats.
  

2. 
   Open ‘logger.py’ either remotely or locally.
   

3. 
   To change the variables for the storing or streaming of webcam
   

1. 
   Scroll down to ‘def startRecord(method):’
   
2. 
   Edit the appropriate variables (frameRate, frameSize, and other important parameters)
   

2. 
   
   
3.
