The audio detection tool is now enabled.
Setting General Parameters of Audio Detection
To set the general parameters of audio detection tools, you must perform the following steps:
1. In the detection tool list, highlight an Audio Detection object (1) which offers a means of
analyzing the audio signal from a microphone connected to the desired video camera.
2. In the Period field (2), enter the time in milliseconds after which the next section of the
audio stream will be processed by the audio detection tools. This value should be in the
range [0, 65535]. If the value is 0, each section of the audio stream is processed.
3. Click the Apply button.
Setting the general properties of the audio detection tools is now complete.
Settings Specific to the Signal and Noise detections
To configure the Signal and Noise detection tools, you must perform the following steps:
1. In the Detection Tools list, highlight a Signal or Noise audio detection.
2. Enter the following values in the Level field:
a. When configuring the Signal detection tool, enter the audio signal level in standard
units above which the detection tool will be triggered. You should select a value
empirically in the range [0, 1000].
b. When configuring the Noise detection tool, enter the noise level in standard units
above which the detection tool will be triggered. You should select a value empirically
in the range [0, 1000].
3. Click the Apply button.
Configuration of the Signal and Noise detection tools is now complete.
