Great question HorizontalMike. The DVR has four RCA audio inputs to which microphones can be connected. The cameras included do not have microphones built in, you would need to purchase them from another manufacturer. Audio recording can be turned on or off as needed. Be sure to review local laws regarding audio recording.
