Meeting rooms in Vectera are by default locked - meaning your clients can’t enter without you being present. Guests will have to knock to enter the room (with or without showing camera) and the host can accept or deny access.

I want to let someone in without knocking
You can manually invite clients to the meeting room to have all-time access to the meeting room. Open the share box at the bottom of the meeting room. Click on the button 'Invite via e-mail', type the email address and click on 'Send invite'. The person will receive an email with a special access key.
You can decide what the access key will do: the person should knock, can always join or has host rights.
