Wylmi allows anyone to start a one way video call with you, simply by scanning a QR code.
To get started, create a virtual intercom within the app and invite residents of your building or co-workers in your company. The app generates a QR code that you can share publicly (ex: on the front door). When someone scans this QR code with their smartphone, the directory of residents appears. They can simply select a name to start a one way video call (you can see the visitors front camera but they can’t see yours). They don't need to install an app, the communication is seamless.
Wylmi also is also able to control the doors of a building with an optional module. You can command an opening any time from the app.
