How would you like to answer your front door from any telephone in the house? See who is at the door before opening it? Talk to one or all members of your household with the press of a button? Wake the kids up for school or tell them dinner is ready without leaving the room you're in?

For those working at home and keeping an eye on small children, home systems allow you to listen to and even watch a child's room or play area through the computer or television. If however, after a hectic day, you're in need of some quiet time, you can make use of the do-not-disturb function.
