Audio Detection
The measurement unit of the SVG's digital audio is dBFS（dB Full Scale）. 0dBFS is the
maximum audio level, corresponding to +24dBu of analog audio.
Audio Overload
The SVG alarm will prompt a warning picture (text or icon) as soon as the audio level
overloads the threshold you have settled. It provides 4 audio channels detection. And
there is a box in front of each audio channel. This detection will take effect only if the box
is checked. The threshold and duration of detection can be configured for detection of
each audio channel. The threshold means a maximum audio level. When the actual
volume is above this threshold, the system will prompt with a warning of audio overload.
Audio in Silence
The SVG will prompt a warning picture (text or icon) as soon as the audio level lowers the
threshold you set. It provides up to 4 audio channels of detection with a check box in front
of each audio channel. This detection takes effect only if the box is checked. The
threshold and duration of detection can be configured for detection of each audio
channel. The threshold means the minimum audio level.
When the actual volume is below this threshold, the system will prompt warning of audio
in silence.
