Working from home is nothing new for me, I have been doing it some weeks at a time for several years. But now that more and more collegues do the same and use teleconferencing tools and apps, I got a small upgrade for my setup: A goose-neck tablet holder, so that it can become a dedicated second screen exclusively for telecons, freeing precious space on the main screen.
Decent video and audio quality are important for collaborating remotely, I believe. And a camera that is positioned such that you look up to it, rather than looking down into, makes a less imposing and awkward image, thereby contributing to a more pleasant atmosphere.
