4.5 Audio Page
The Audio page provides configuration settings for the camera's audio input and output.
The On/Off buttons affect all audio input and output. Turning audio off immediately turns off all camera
audio.
Audio In
When audio is On, the following audio input settings appear:
· Encoding—G.711.
· Bit Rate—The camera supports an audio input bit rate of 64 kilobits per second (kbps).
· Sampling Rate—The camera supports a sample rate of 8 kHz.
· Enable Multicast—Can be set to On (default) or Off. When On, specify the destination address and
port, and the time-to-live (TTL).
Audio Out
When audio is On, you can adjust the audio line output gain from 0-100 percent. The default gain is 80
percent.
Tips
· Test whether the camera's audio output is functioning properly by clicking Play.
· If you are monitoring the audio IP output with a video stream and change any of the audio
configuration settings except gain, restart the stream. For example, if you are monitoring a video
stream and turn audio on, you need to restart the stream to hear the audio with the stream.
4.6 I/O Devices Page
The I/O Devices page provides configuration settings for external I/O connections and the device
managing those connections with the camera.
