AXIS 2420 User’s Manual The AXIS 2191 Audio Module 43
Simplex - Talk
Simplex - Talk mode means that only the web-client end of the connection can transmit
audio (that is, to the AXIS 2191). This could be used, for example, to provide spoken
instructions to a person seen in the network camera. This mode also requires you to use the
Push-to-Talk button.
Simplex - Listen
Simplex - Listen mode can only receive audio from the AXIS 2191 to the web-client. This
can be used in remote monitoring, web attractions etc., to provide live audio, as well as
video, of a monitored situation.
