In this video, we show you how to use a Raspberry Pi 3 (you could also use a Raspberry Pi 4) to power a DIY Smart Doorbell. The smart doorbell opens a virtual meeting room for the guest when they press the button. It also sends a notification to your phone with a link to the same meeting room so that you can chat with the guest. Make two of these doorbells and they can join the same meeting room and be used as a video intercom system.
