It also adds to your security by letting you identify guests before you open your home to them. Know Consider using an intercom doorbell system if you feel unsafe opening the door before you know who is on your doorstep. Intercoms also make answering the door easier for those who have difficulty walking. With an intercom, you can greet your guests immediately, but take your time getting to the door. Some intercoms even have a special feature that allows you to remotely unlock the door from inside the house.
Intercom doorbells consist of an outdoor unit and an indoor unit.
A visitor uses the outdoor unit to ring the doorbell and then respond to you when you inquire about his or her identity. The indoor unit chimes when the doorbell rings and allows you to talk, listen to, and sometimes even see the visitor. These intercoms let visitors and homeowners talk to one another, with the touch of a button, through speakers that are mounted outdoors and indoors. The more indoor speakers you install, the more convenient it will be to reach a speaker quickly. You can also use indoor intercom speakers to communicate easily with family members and guests who are inside the house.
