“Raspberry Pi-powered hardware that notifies you when guests arrive and lets you talk to them on your phone through internet calls.
Need another way to social distance yourself during the COVID-19 outbreak? Make this smart doorbell system so that you don’t have to interact with guests at your front door. The system can also be used as smart intercom system so that you can chat through internet calls with other people in your home or office.
The Raspberry Pi-powered Smart Doorbell opens a virtual meeting room for the guest when they press a button. It also sends a notification to your phone with a link to the same meeting room to chat with the guest. Make two of these doorbells and they can join the same meeting room to be used as a video intercom system.”
