This setting is used by the DIR911t to decide if there is enough voice activity on the
telephone or auxiliary line to start recording. If at any time the voice level on the
telephone line is above this value and the “line” setting in the line activation mechanism
screen is enabled the DIR911t will activate the line and start recording. If at any time the
auxiliary level is above this value and the “aux” setting in the line activation mechanism
screen is enabled the DIR911t will activate the line and start recording.
