WebCompanion Settings:

  • Open the WebCompanion Software.
  • Open the Capture menu:


  • Open Webcam Settings and make sure that the screen is viewed by the webcam entirely.
  • Click on Webcam Settings (see the yellow circle on the top right corner)



  • In the new window that opens, click on Advanced

  • On the Camera Control tab, remove the checkmark from the Exposure auto checkbox, set it to -6, and press OK. Note that if you will not remove this check you will see a delay while drawing.


  • Close the WebCompanion software. Note: If you do not close it completely and only minimize the window, the calibration process will not succeed. Make sure that the screen is black.
  • Run AIRGraffitiMgr.exe and maximize it to the whole screen.
  • Click Air Graffiti > Calibrate > Start.

  • Once you click “Start”, A red circle will appear on the screen and a “Tracks” Window will open. The “Track” window shows you how the IR Webcam sees the screen, if it’s black and no blue rectangles appear, the IR camera position is good and you can minimize this window and start the calibration. If you see showing blue rectangles, it is due to an external light hitting the IR sensor.
  • Minimize the “Track” window and use your Infra-Red can and spray in the middle of the red circle until you see a blue circle appear inside. Repeat this process with all the circles on the screen (10 circles).
  • Once done with the 10 blue circles, blue “+” signs will appear inside the red circles. Continue with the calibration process 10 more times.
  • Once you are done with the 10 circles and 10 “+” signs (it’s ok to do more), Click Air Graffiti > Calibrate > Stop.



  • Click on Air Graffiti again and select Draw. This will minimize the screen.

Software Settings:

Open the AIR Graffiti software > Open the settings menu (Ctrl+O) > select Infra Red Technology.
