6.6.6 Audio Alarm
Create alarms based on audio signals. Configure signal
strengths and frequency ranges so that false alarms, for
example, machine noise or background noise, are avoided.
Set up normal audio transmission before configuring the audio
alarm.
Audio alarm
Select On for the device to generate audio alarms.
Name
The name makes it easier to search for or identify the alarm in
extensive video monitoring systems, for example with the
Bosch Video Client and Bosch Video Management System
programs. You can also use the name in the Forensic Search
program function as a filter option for quick search in
recordings. Enter a unique and clear name here. (Do not use
any special characters, for example &.)
Signal Ranges
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 Set the threshold using the slide control or,
alternatively, move the white line directly in the graphic using
the mouse.
Sensitivity
Use this setting to adapt the sensitivity to the sound
environment and effectively suppress individual signal peaks. A
high value represents a high level of sensitivity.
