Clicking on Go to device settings will take you to the settings tab of the device to which the channel directly belongs.
To configure the video channel, click the Video button.
The Audio channel settings window is divided into several areas. In the middle of the window you will see a oscilloscope representation of the audio coming from the camera's microphone.
In the Audio Parameters group of settings, you can set the volume level and quality of the audio stream. When you move the sliders, the new settings are sent to the device, so changing the position of the sliders may not change the sound from the camera immediately, but with some delay. If the Leave defaults flag is set, the volume and quality of the audio stream are defined by the parameters set in IP camera's web interface.
If the audio stream of the device is of meager quality, the sound is muted or absent, choose a channel from the Default Sound dropdown list to play its audio stream with the video. If the channel chosen as the sound source has Archive recording enabled, the audio stream will play with the archive playback. Nevertheless, there will be no sound after the Archive export. Apart from that, if the channel archive chosen as the sound source contains no video, the audio stream will not be available for playback.
Tip
Make sure that the flag Audio is checked in the device's settings for the audio channel to appear in the list of the available audio sources. Read more in Configuring device settings.
In the Software Detectors settings group, you can enable and configure the detector in the Sound Detector:
- Disable - Turns off sound detection on this channel.
- Any sound - Enables detection of any sound.
The activation threshold is depicted on the oscilloscope diagram in the form of two horizontal lines. When the sound level exceeds these lines the oscilloscope representation changes from green to red. Use the slider to adjust the Threshold. The sound detector will only be activated when the sound level exceeds the specified threshold. In other words, if there is a source of constant sound, such a road, near the camera's microphone, then in order to avoid activating the detector when a car passes by, set the activation threshold above the sound level of a passing car.
Set the Record on Sound to start recording to the archive when sound is detected.
If the Generate Sound events checkbox is set, each time sound is detected a new event will be written to the database. It may be necessary to disable this feature to reduce the load on the database.
Tip
Depending on the device being used, one or more settings may be unavailable.
