What are the smiling emojis at the top for?

They indicate presence detection via the camera. Several detected faces correspond to several emojis. They are not customizable.

The translation icon doesn’t appear — what should I do?

The option may not be enabled. In that case, an administrator can enable it in the advanced settings.

To go further: Translation.

Connection and security

Do I need an Internet connection?

Yes. Internet connects la Vitres to each other and enables remote assistance.

What connection types are possible?

la Vitre works on a wired or wireless network. For a stable experience, prefer Ethernet or a reliable Wi‑Fi.

Recommended bandwidth

For a Full HD 1080p exchange between two la Vitres:

  • 5 to 10 Mbit/s upload and download
  • Stable latency below 50 ms
  • Video sending around 1881 kbps per stream in 1080p, minimum 1000 kbps for device sharing
  • An ADSL line with around 1 Mbit/s upload is not enough for 1080p. Requirements increase with the number of la Vitres used at the same time.

Are your exchanges secure?

Yes. End-to-end encryption, protected signaling (HTTPS), WebRTC integrity control, no server-side storage of content.

Test your connection on la Vitre

The “three dots” menu lets you run the connection test. The window (white label) is only visible on the la Vitre being used.
