AXIS P3301 Fixed Dome Network Camera Video and Audio Input gain - Control the volume (dB Full Scale) of the audio input. If the sound is too low, choose a higher dB, to amplify the sound. If the sound is too high, choose a lower dB. The Level bar gives a visual representation of the audio signal level in dB relative to the full-scale input level. • Green — the signal is at a good level. • Yellow — the signal is becoming distorted. • Red — the signal is distorted. Encoding - Select digital audio encoding format. • AAC requires a license for both encoding and decoding. AAC is the least complicated and most widely used codec. If achieving the best possible audio quality is a priority, AAC is the recommended codec to use. An AAC license is included in the Axis product. • G711 • G726 Sample rate - The number of times per second the sound is sampled. A higher sample rate will provide better audio quality, but also requires a greater bandwidth. Bit rate - Set the required bit rate depending on the selected encoding. A higher bit rate will give better audio quality. A lower bit rate may have latency or delay, but will require less bandwidth. For more information about these settings, please see the online help . Audio Output An external speaker can be connected to the product’s Audio-out connector. The output can be used with high impedance headphones or connected to another amplifier with speakers. Configure the audio output settings under Video & Audio > Audio Settings. Output gain - Control the volume (dB Full Scale) of the line audio output. If the sound is too low, choose a higher dB. If the sound is too high, choose a lower dB. Audio Clips An audio clip is a sound file that can be played either when an event occurs or manually from the Live View page. Audio clips can be uploaded to the product or recorded by a microphone connected to the product. You can add, play, download, modify and remove audio clips from Video & Audio > Audio Clips. For more information see the online help . Note Audio clips cannot be used if the product’s audio functionality is enabled.
