Through the use of a central station and a speakerphone, the monitoring centre can communicate with the home's occupants or an intruder. In case of a medical emergency, this could be helpful for the owner. When an actual break-in has occurred, the central station can use the speaker phones to ask the invader to leave while they provide help. In the United Kingdom, "listen-in" alarm monitoring goes by a few different names: "Immediate Audio-Response monitoring," "Speaking Alarm Systems," etc.
