Coviu prides itself on its ease of use, whereby its software works on even the most basic inbuilt webcams, speakers and microphones. Coviu is browser-based and therefore works on the majority of commonly owned devices such as laptops, desktops, iPhones or tablets. However, to improve the audiovisual quality of your calls, or if your device does not come with a camera, speaker, or microphone, or if you'd like to add a document or medical camera, additional hardware may be of use to you.
