YouTuber Builds a Cool DIY Raspberry Pi 3 Smart Doorbell With Camera
Here are some of its perks: When the guest presses its button, the smart doorbell opens a virtual meeting room and sends an email notification to your phone with a link to the same meeting room.
If you make two of these doorbells, they can join the same meeting room, and you can use this as a video intercom system. Moreover, it could be used as an always-on intercom system for your office too.
Thanks to this doorbell you can have a semi-awkward video call with your guest before they can even come in.
However, this YouTube user has a very good point. "It will be much cooler and safe if the email notification is also capture [sic] the image when someone rings the bell, so you can prepare to welcome the guest or pretend you aren't in home [sic] to avoid people you hate hehe." We're waiting on them to contribute to the codebase.
