Please check the following:

1. Check if the webcam is plugged in correctly.
   For the details of how to check if webcam is plugged in correctly, see Check to make sure the webcam is plugged in correctly.
2. Check if the webcam is working.
   For the details of how to check if webcam is working properly, see Check to make sure the webcam is working properly.
3. You may have insufficient resources (bandwidth, processor availability).  Check your 5-bar System(1) and Connection(2) Ratings in the lower-right hand corner of meeting room.  Mouse over the rating displays for more detail.  If needed, reduce video displays or size of the live sharing area.  Close other applications.
   
   

   We recommend that you use the wired Internet connection.

4. Extreme packet loss may have occurred.  (e.g., an intermittent wireless connection or a poor IP route).  You can try to establish a better connection by closing OmniJoin meeting and re-entering your meeting.  Do not forcibly close the meeting (i.e., with task manager), as then you will have to wait a few minutes to re-enter your meeting room (the OmniJoin cloud is still awaiting status on your old connection).
