SELECTING AUDIO CONFIGURATION SETTINGS
To use audio with the camera if it does not have built-in audio support, you must connect an audio device to the accessory port. Once the device
is connected, audio can only be enabled through the primary stream.
Audio and video may not be synchronized when viewing and listening to the primary stream through a Web browser. You may experience a
three-second delay in video when viewing the primary stream with audio.
NOTE: Improper use of audio/visual recording equipment may subject you to civil and criminal penalties. Applicable laws regarding the use of
such capabilities vary between jurisdictions and may require, among other things, express written consent from the recorded subjects. You are
solely responsible for ensuring strict compliance with such laws and for strict adherence to any/all rights of privacy and personalty.

5. Select the sample rate from the Sample Rate drop-down box. The sample rate is the quality of the audio stream (rendered in hertz per

8000 Hz.
6. Select the encoding method for the audio device from the Encoding drop-down box. Available encoding methods are PCMU, PCMA, and

Mute located on the Audio Configuration page.
9. Set the sensitivity of the input level by moving the Input Level slider. Move the slider to the right to increase the sensitivity level; move it to
the left to decrease the sensitivity level. For example, if the camera is installed in a noisy environment or the connected microphone has a
built-in line amplifier, set the sensitivity to a low setting. The setting range is 0 to 100.
