AXIS 215 PTZ/AXIS 215 PTZ-E - Setup
16
If Microphone is selected - set the Input sensitivity to:
• High if the connected microphone is an ordinary (unamplified) microphone, e.g. a computer mic or
clip-on mic.
• Low if the connected microphone has a built-in line amplifier.
Enable microphone power - microphone power should only be used with an electret microphone without a
battery. This setting should not be enabled when using a dynamic or battery powered microphone.
Input gain - volume control of the audio input. The Input sensitivity levels High and Low are volume settings
made earlier in the audio path (see above).
Note: Low Input sensitivity should never be compensated by a high Input gain, as this may cause unwanted
noise.
Encoding - select the digital audio encoding format to use.
Bit rate - depending on the selected encoding, set the required bit rate (audio quality). The higher the bit rate,
the greater the bandwidth required.
Alarm level - event types in the AXIS 215 PTZ can be set to use this level as a trigger. Each individual event
type can be configured to trigger if the sound level rises above or falls below the set value.
The alarm level can be set in the range 0-100%, where 0% is the most sensitive and 100% the least sensitive.
Audio Output
If the sound from the speaker is too low or high it is possible to adjust the output gain for the connected active
speaker.
When satisfied with the settings, click Save, or click Re set to revert to the previously saved settings.
