Audio Clips - Axis Q1910 User Manual

Note: The Talk/Listen button is configured from the Audio tab in the AMC Control panel (see AXIS Media Control
(AMC), on page 17).
Simplex - Thermal Network Camera speaker only. Audio is transmitted from the client to the camera and played by
•
the speakers connected to the camera. To send audio, the Talk and Microphone buttons in the AMC toolbar must both
be enabled. Click either button to stop audio transmission.
Simplex - Thermal Network Camera microphone only. Audio captured by the microphone connected to the camera
•
is transmitted from the camera to one or more clients.
Audio Input
An external microphone or a line source can be connected to the Audio in connector. If an external microphone or line source
has been connected, the internal microphone is automatically disconnected. The audio source must be set to Microphone or
Line depending on the connected device.
Notes:
• To prevent unauthorized listening, disable the internal microphone by inserting a plug in the Audio in connector.
• The internal microphone on AXIS Q1910-E/Q1921-E/Q1922-E cannot be used.
The Enable microphone power option provides DC power for an external microphone. If using a small electret condenser
microphone such as a clip-on microphone or a PC microphone, enable this option.
Notes:
If Enable microphone power is unchecked (disabled), the internal microphone is also disabled.
•
• To use a high impedance dynamic microphone, do not enable DC power. DC power will not harm the microphone;
if you are uncertain, try switching it off and on. The default value is DC power enabled. To use a professional
microphone requiring 48V phantom power, you need an external power supply and a balanced-unbalanced
converter (audio transformer) in between.
If the sound input is too low or too high, adjust the input gain for the microphone attached to the network camera.
Select the desired audio Encoding format, G711 μ-law, G726 or AAC.
Select the required Sample rate (number of times per second the sound is sampled). The higher the sample rate, the better the
audio quality and the greater the bandwidth required.
Changing the Bit rate affects the audio compression level and hence audio quality. A higher bit rate can improve audio quality
but requires more bandwidth.
The network camera can be configured to trigger an event if the incoming sound level rises above, falls below, or passes the
set Alarm level.
Audio Output
If the sound from the speaker is too low or too high, adjust the output gain for the active speaker attached to the network
camera.
Note:
To receive synchronized video in H.264 and audio, it is recommended that the time settings in the camera and client
computer are synchronized with an NTP Server. This is enabled in the camera under System Options > Date & Time.
Please refer to the help pages for more information.
