 Hi, I'm Andy from Readle and in this video we're going to be talking about the meaning of the term panel. Now when I say panel, I'm not talking about a group of big important people who sit together in a room and take very important decisions. Nope. In Intercom World, we're talking when we say panel about something like this. It's an article that has three main elements. There is, first of all, an audio input, something like a microphone. Secondly, we have an audio output, so that will either be headphones or some kind of loudspeaker. And thirdly, there'll be a control element, typically kind of buttons that you can just press. Now a panel is used when a user wants to communicate with someone else. Typically they will push a button, speak into the microphone, and their voice will be transmitted through the Intercom to the target destination. One cool thing about Readle panels is that the configuration is not stored in the panel itself. The configuration is stored in the frame, which means that if you were to, by accident, spill a cup of coffee on the panel, and it doesn't work anymore, then you simply replace the panel with a new one. No need to reconfigure anything, you just plug and play.
