The sound activated audio trigger recording mode is the a mode , in which audio signal recording starts at the moment , when the volume of the audio signal power exceeds a preset level and is shutdown ends at the moment , when the volume of the audio signal power becomes lower than the preset level that has been previously exceeded earlier.

To set up the sound activated recording, Axxon PSIM™ software uses the settings:

  1. Level - When audio signal power exceeds a threshold value (Level setting) during a preset interval (Delay), audio signal recording starts automatically(alarm’s registration).
  2. The Delay setting defines the  time interval, during which audio signal is prerecorded after the end of alarm.

Sound activated recording is adjusted separately and independently for any microphone. It is recommended to select the optimal settings by trial and error to avoid malfunction.

By default, sound activated audio signal recording is disabled.

audio trigger recording in Axxon PSIM, you can use the following parameters:

  1. Audio trigger level determines the threshold level of audio signal power above which audio recording (alarm event registration) is automatically started.
  2. Audio trigger delay determines the time during which the audio signal is post-recorded after the end of an alarm event.

You must configure the audio trigger recording separately for each microphone. We recommend selecting the optimal values of the audio trigger recording experimentally to avoid false positives.

By default, the audio trigger recording is disabled.

To configure the audio trigger recording, do the followingEnabling and setting up the sound activated recording option for a selected microphone is done in the following way:

  1. Select the disk(s) to store audio trigger recordings in the sound activated mode (see . Selecting the disks for audio archive storage).
  2. Set Configure the Audio player object to operate with the selected microphonesmicrophones, the audio signal from which must be recorded by audio trigger (see Configuring audio signals playback using the Audio player object).
  3. Go to the settings panel of the Microphone system object settings panel.

  4. Set Move the slider Audio trigger to level slider to the position , corresponding to the required level of video signalaudio threshold power. The current threshold level in conventional units is displayed in the field on to the right of the slider.Image Removed
  5. Set Move the Audio trigger delay slider to the position , corresponding to the required delay time of audio signal audio post-recording time after the end of an alarm event. The current delay audio post-recording time in sec seconds is displayed in the field on to the right of the slider.
  6. Click the Apply button to save all the changes.
  7. With Use the help of Audio player object to check if the sound activated audio trigger recording is initialized , when the sound an audio signal of the required volume is fed to the microphone. If notrecording isn't initialized, reduce the value of Level the Audio trigger level parameter by moving the Level slider some points a few divisions to the left (see step 4-5 steps).With
  8. Use the help of Audio player object to check , if the sound activated audio trigger recording is initialized , when the sound signal of lower volume, an audio signal with a volume level lower than the required one is fed to the microphone. If yes, move the Level slider some points recording is initialized, increase the value of the Audio trigger level parameter by moving the slider a few divisions to the right (see step 4-5 steps) to increase the setting value.
  9. Repeat steps 7-98. If the sound activated recording is properly set upaudio trigger recording works correctly, complete the set up setting procedure.
