Essentially, you just need internet access, a camera, microphone and speaker. Most modern smartphones, tablets and laptops have these built-in as standard.
Smartphones are okay, but a desktop PC, laptop or tablet are better, with their larger screens for easier viewing.
If you’re using a desktop PC that doesn’t have a built-in camera, a simple USB camera/mic is very easy to install. At the time of writing, we recommend the Logitech C922 Webcam. Just plug it into a USB port and you’re ready to go!
