Here's how to set up your webcam to play automatically, without users having to press the play button, when they come to your web site (note:  This will not work on mobile as there is no way to auto-start a video on a mobile device.)

1. Log in to your Dashboard
2. Navigate to WEBCAMS
   
3. Select your WEBCAM STREAMNAME: yourwecamstreamname
   -> Click Manage (green button)
   
4. Go to the Camera Settings 
   
5. Click small pencil icon next to the Autostart option
6. Click Enabled

Done.
