Audio Hardware and audio data requirements for the operation of the Audio classification IV

Note

Attention!

The Microphone object must be enabled (see The Microphone object).

To configure the Audio classification IV, do the following:

  1. Submit to the technical support the MAC address of the Server server where the detector will be used.

    Note
    titleAttention!

    The detector will not work on the Server server with a different MAC address.

  2. Copy the license received from the technical support into the C:\Program Files\Common Files\AxxonSoft\DetectorPack\LicenseFile_AudioIV.txt file.
  3. Restart the Server server (see Shutting down a Server Stopping the server, Starting a Serverthe server).

  4. On the Detection Tools tab Detectors tab, below the required camera, click Create… → Category: Production Safety → Audio classification IV.

By default, the detector is enabled and set to recognize and detect all sounds specified in the settingsthe following types of sounds:

  • the sound of aggressive behavior,
  • the sound of a gunshot,
  • the sound of a smoke alarm,
  • the sound of a child crying,
  • the sound of breaking glass,
  • the sound of a siren,
  • the sound of a dog barking.

If necessary, you can change the detector parameters. The list of parameters is given in the table:

Note
titleAttention!

Recommendation for the sound detection threshold parameters: start with a value of 0.99 and gradually lower it if the detector misses target events, or increase it if there are too many false events.

  • A high value (close to 1): lower sensitivity, fewer false events, but a higher risk of missing an event.
  • A low value (close to 0.01): high sensitivity, better detection, but more false events.
