Home intercom
The majlis and the kitchen, grandma's room and the living room, the shop and the store room, the villa and the annex: two phones on the same Wi-Fi become a voice-and-video intercom in a tap — no app, no account, no number, and nothing passes through any server. Scan a code from each side and that's it. Also works for kids without SIM cards.

How to use it
- On the first phone: press «Start» and allow camera and mic — a QR code appears.
- On the second: press «Join» and scan the code — a reply code appears; scan it with the first.
- Talk. «Mute» and «Camera» per side, and full screen if you mount the phone on a stand.
Questions
Does it need internet?
It needs a network (home Wi-Fi is enough even with the internet down on most routers, because the connection is direct inside the network). The public STUN server is used only for introductions when the two are on different networks.
Does the call pass through you?
No; WebRTC is direct between the two phones and encrypted. We have no server in the middle and no account.
Why two codes?
The first carries the connection «offer» and the second the «answer» — without them the devices would need a mediating server. Scanning takes seconds, once per session.
More than two devices?
The intercom is between two devices per session. For three rooms open a session per pair.
