(2018-02-22) It worked great until it stopped working when we switched to Google Meets
(2018-01-24) Tanner Taylor: Didn't work for me either just like Lee said. Joined the call with a coworker and camera was on by default
(2018-01-08) Lee Moreau: So this doesn't even remotely work. I set it to disable camera by default. Joined a Hangouts call and then 3CX webmeeting and both of them popped up me on video right away. Useless.
(2017-05-19) Matthias Danetzky: Finally I can remove the ugly band-aid from my notebook's camera.
(2017-04-11) Miguel Enciso: excelente, falta meet google
(2017-02-08) Nikhil Mathew: Google didn't care to include it.
You did it for us. Thanks a ton.
(2017-01-11) Bron Davies: Finally! Turns off the camera (and/or mic) by default in Hangouts.
