Audio

“Transmission mode” There are five options to select. For all the modes, only one client can talk to the server at the same time.

“Full-duplex (Talk and listen simultaneously)” In this mode, the User can talk to the server while listening sound from the server simultaneously.

“Half-duplex (Talk or listen, not at the same time)” In this mode, the User can talk to the server or listen from the server, but not at the same time.

“Simplex – Talk only” In this mode, the User can only talk to the server. “Simplex – Listen only” In this mode, the User can only listen from the server. “Disable” In this mode, the audio is disabled in both directions.

“Send audio from the active client to all the other clients” In half duplex transmission mode, select the option to talk to the server and broadcast your voice to all the other clients.

“Improve audio quality in low bandwidth environment” If the Network Camera works in versatile or low network bandwidth environment, the User can check this option to improving audio quality by sacrificing some real-time synchronization.

“Audio source” Select source from external or built-in microphone.

“Acoustic echo cancellation” In full-duplex mode, the server can play sound from the client and receive sound from the environment and send to client. Since the sound from the client is played by server, it will also be received by the server’s microphone and send back to client. That is the client will hear its echo. Select this option can prevent echo by sacrificing the video frame rate.

“Bit rate” There are three kinds of bit-rate for audio. 32Kbps and 24Kbps are suitable for both music and speech like audio while 8Kbps are suitable for only speech like audio.
