You guys are right about that. But first to be clear. This is NOT our HQ, but an office not working on our core- platform. People sitting in this office can look out of the window to see who's standing at the door before opening the door.
Also, please note, this was just a fun small project for us. Making an image with a camera and posting to Slack would be better. We had much fun making this without putting a lot effort in it, that was for now the point.
We are aware of all the security issues and are not using this in production at our main office.
