Audio Modes

• Full Duplex - Bi-directional communication that allows simultaneous transmission in both direc-

tions, as used in telephone systems. This type of communication requires a full-duplex sound card

installed on your computer. The full-duplex mode can be used for e.g. virtual meetings.

Note: This type of communication can only be used if your sound card supports full-duplex.

• Half Duplex - Bi-directional communication that transmits in one direction at a time. The one end

of the connection must be silent to receive audio from the other end. A walkie-talkie is a good

example of this type of communication.

• Simplex - Talk - Audio communication is one-way only. Use this to, for example, provide spoken

instructions to a person waiting at a door that is monitored by the camera.

• Simplex - Listen - Also one-way only. This can be used, for example, for remote monitoring.
