How it works
- Devices: Participants connect using webcams built into or attached to laptops, desktop cameras, tablets, or smartphones.
- Software: A video‑conferencing platform (app or web service) transmits audio and video over internet protocols, often adding features like screen sharing, chat, recording, and virtual backgrounds.
- Dedicated setups: Some organizations use purpose‑built conference rooms with high‑quality cameras, microphones, speakers, and large displays for better audio/video and fewer technical issues.
- Network dependency: Call stability and quality depend heavily on internet speed and reliability.
