AXIS Q6052 PTZ Dome Network Camera
Video and Audio
There is no echo cancellation; if feedback loops appear, try moving the microphone or the speaker.
•
Half-duplex – Audio can be transmitted to and from the Axis product but only in one direction at a time. To transmit
audio using the Live View page, use the Talk and Listen buttons, see AMC Audio Controls on page 12.
•
Simplex – Network Camera speaker only - Audio is transmitted from a client to the Axis product and can be played by
a speaker connected to the product. To transmit audio using the Live View page, the Talk and Microphone on buttons
must both be active, see AMC Audio Controls on page 12.
•
Simplex – Network Camera microphone only - Audio captured by the product microphone is transmitted from the
Axis product to one or more clients.
To set the audio mode, go to Video & Audio > Audio Settings and select the desired mode from the Audio mode drop-down list.
Audio Input
An external microphone or a line source can be connected to the Audio-in connector. Configure the audio input settings under Video
& Audio > Audio Settings.
Note
An Axis multicable is required when connecting external audio equipment to the Axis product. See Axis multicable on page 63.
Use the Input gain to control the volume of the audio input. If the sound is too low, choose a higher dB value, to amplify the
sound. If the sound is too high, choose a lower dB value. 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.
Use the Encoding option to 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 is an unlicensed standard codec that is useful when integrating audio into a VoIP system
•
G726 is an unlicensed speech codec that is most commonly used within the security industry.
Note
The Sample rate defines 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.
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 Audio-out connector (an active speaker with built-in amplifier is required for this). The
output can be connected to another amplifier with speakers. A stereo connector must be used for the audio out.
Configure the audio output settings under Video & Audio > Audio Settings.
Note
An Axis multicable (see Axis multicable on page 63) is required when connecting external audio equipment to the Axis product.
