Having an intercom system designed into your home or business can save a lot of time and frustration trying to find someone or to individually speak to someone. With an intercom installed you have an all call button so all stations are accessed, individual room call for private conversation, hands free access, listen in for example a baby’s room, do not disturb for privacy and phone access for your outside doors. This will ring the phone if someone is at the door which also gives you audio access to the door.
