18.9 Advanced Settings > Audio Alarm
Some encoders can create alarms on the basis of audio signals. You can configure signal
strengths and frequency ranges in such a way that false alarms, for example due to machine
noise or background noise, are avoided.
Note: First set up normal audio transmission before you configure the audio alarm (see
Advanced Settings > Audio page).
Audio alarm
Select On if you want the device to generate audio alarms from the input in question.
Name
The name makes it easier to identify the alarm in extensive video monitoring systems, for
example with the VIDOS and Bosch Video Management System programs. Enter a unique and
clear name here.
CAUTION!
Do not use any special characters, for example &, in the name.
Special characters are not supported by the internal recording management and may
therefore result in the Bosch VMS Archive Player being unable to play back the recording.
Signal Ranges
You can exclude particular signal ranges in order to avoid false alarms. For this reason the
total signal is divided into 13 tonal ranges (mel scale). Check or uncheck the boxes below the
graphic to include or exclude individual ranges.
Threshold
Set up the threshold on the basis of the signal visible in the graphic You can set the threshold
using the slide control or, alternatively, you can move the white line directly in the graphic
using the mouse.
Sensitivity
You can use this setting to adapt the sensitivity to the sound environment. You can effectively
suppress individual signal peaks. A high value represents a high level of sensitivity.
