# Network requirements

> Connectivity required for reliable Video sessions

Video sessions run over a standard broadband or mobile internet
connection. **Home Wi-Fi, mobile data, café, hotel and hotspot
networks all work out of the box** — there is nothing to install or
configure.

## HTTPS is mandatory

Browsers only allow camera and microphone access on pages served over
HTTPS. The hosted meeting URLs we provide are always HTTPS. If you
embed the meeting in an `<iframe>` on your own site, that page must
also be HTTPS.

## Bandwidth

The meeting automatically adjusts audio and video quality to the
connection it detects — there is no fixed minimum. In practice:

* A stable broadband, 4G or 5G connection is comfortable for a
  one-to-one meeting with video.
* A weaker connection still works, with reduced video quality or
  audio only.
* The most common cause of a bad meeting is **Wi-Fi signal or
  contention**, not raw internet speed. A "fast" Wi-Fi with many
  devices on the same router can feel worse than a slower but
  stable link.

## Things that hurt quality

* **Weak Wi-Fi signal** or being far from the router.
* **Competing traffic** on the same network — large downloads,
  another video call, cloud backups.
* **Switching networks mid-call** (moving from Wi-Fi to cellular).
  The meeting reconnects, and sometimes drops.
* **VPNs** — many VPN clients route real-time traffic over paths
  that add latency and cause stutter. If a user reports bad
  quality while on a VPN, ask them to try without it.

See [Troubleshooting](/guides/video/troubleshooting) for
symptom-driven fixes.

<Note>
  **IT administrators on restricted corporate networks** — if outbound
  traffic is filtered by a firewall, see the
  [IP allowlist guide](/guides/network/ip-allowlist) for the ports and
  hostnames to permit.
