We're using TeamViewer at the college to be able to remote in. My boss and I are the two main users. We've used it to remote into our desktops so we can monitor the HVAC program at the college, access control, etc. Plus, if we need to grab files, or something, off of our personal computers at work, we can.
My boss and I both have TeamVeamer installed on PCs at the campus. We have the app on our mobile phones. I have it on my personal laptop at home along with my tablet at home.
We remote into PCs at the campus, and one of those PCs is used as a server.
We are using the latest version. We are using TeamViewer 15. I think we started on version 13.
