At what volume does the Lyric C2 camera recognize the sound of a baby's cry?

It depends upon the level of background noise in the baby room. To accommodate different levels of background noise in different residential homes, C2 can be configured to operate in three different levels of listening sensitivities: Low, Normal, and High. When setting Audio Sensitivity to Low, only loud crying sounds from older babies (such as 12 or 18 months old) may be detected by C2. On other hand, when setting Audio Sensitivity to High, a very soft crying sound may be detected as a baby crying act.

Using a strict technical measurement, the loudness of a baby crying sound is defined in a term known as signal to noise ratio (SNR). This can be measured using a high-fidelity microphone connected to a computer placed next to the C2. If the SNR measurement of a baby crying sound recorded by such a sound recorder is 15dB or greater, the C2 should detect the crying sound if it lasts longer than 6 seconds.
