I use LifeSize Video (version 9.0.142, UVC 3.1) on Windows 7 with the Logitech webcam C920. There I found a strange bug relating to the activation of the webcam. If LifeSize video is minimized, sometimes the webcam is turned on for no reason. I guess the problem has something to do with the energy-saving mode of the PC, but I can not describe the issue exactly.
Of course you can deactivate the cam again by open and close Lifesize video. But IMHO the bug is nevertheless critical because our users might feel observed in their office.
Does anyone found the same issue? Can you describe the bug in more detail?
