Webserver Software

Each AVN-TB talkback unit has a built-in web server for setup and configuration. The web server is responsive, and resizes depending on the size of your screen, meaning that it can be used on large monitors or small handheld devices such as smart-phones. Help information is shown on the right-hand side of the screen so it’s a good place to go to find out how the unit operates.

Key Features

  • 20 illuminated key-cap Talk buttons plus Listen & Page buttons.
