For audio detection, the device (ex. DirectIP camera) calculates the average power of audio signal that is transmitted for specific times (6.5 seconds).<\/p>\n

If current audio signal\u2019s power is much higher than the power threshold of audio signal (based on the average power of audio signal), then audio detection is enabled.<\/p>\n

That is,<\/p>\n

    \n
  1. Gather audio signal for 6.5 seconds<\/li>\n
  2. Calculate the average power of audio signal<\/li>\n
  3. Compare current power of audio signal with the power threshold of audio signal<\/li>\n
  4. Decide whether audio is detected or not.<\/li>\n<\/ol>\n

    The threshold of power level is determined by the audio sensitivity level.<\/p>\n

    * Sensitivity level 1: two times (6dB) higher than the average power of audio signal<\/p>\n
